> Interestingly, in all cases urban roads are worse quality than rural roads, presumably because they see higher traffic than rural roads.

There's more infrastructure under urban roads. Crews come in to fix some utility, shred a section of a lane, patch it poorly with dissimilar materials, and leave.

burnte5 hours ago

This happens CONSTANTLY in Atlanta. They'll spend a bunch of money fixing a road, then a month later Public Works digs a huge hole and leaves a steel plate on it for a year, then patch it with either concrete that is an inch or two below the rest of the surface, or they don't pack the earth they put back and in 3 months the patch has sunk into a new pothole in a brand new road. The city has been trying to force public works to go do those things BEFORE road projects, but it's an uphill battle.

This happens in other countries too. Some people theorize that it's done because of internal rivalries between dependencies/political factions, but I suspect local governments are just inept at logistics.

jakjak1235 hours ago

Its also a difficult problem. They need the right digger and the right crew at the right time and possibly the right weather to get the job done. Many times there will be weeks of juggling around schedules and suddenly the digging started three weeks after the road was finished

Here, the gov gives time windows for utility owners to dig and do maintenance, after which it'll be repaved. If you want to do maintenance on your infra, you request a timeslot and the gov groups the maintenance (eg sewer and gas). You best not miss your window.

We were getting our roads redone in my town and the county commissioner ordered an asphalt miller to run on one singular road, when we needed it (and said for it to run) on all of them. It cost us the same to run it on one road or all of them, because most of the costs were transport of machinery. So I definitely lean towards ineptitude.

LeanderK2 hours ago

interesting. I noticed something similar in the UK but not in Germany. Maybe some simple change in the way these utility repairs are regulated is to blame?

While interstates are nice, cities are where people live, so the quality of urban roads matters and is maybe the reason for the perception of US roads?

Probably everywhere frankly, but Dallas is terrible, too. My wife and I took up skateboarding recently and it became much more obvious. Go out to the suburbs or a running trail or nice park and it's smooth sailing. You can push and coast. Where we live near downtown, it's cracks, rocks, discontinuities, metal plates. The gas company also dug up a bunch of bedrock 7 years ago, left a huge pile of it on the corner, rain came a few days later, and for the last 7 years, our sidewalks have been covered in dirt and the houses and cars all get a thin yellow film on them because there is so much dirt in the air all the time.

That's before considering what regular construction crews do. Most of the sidewalks are closed most of the time. They're routinely torn out and never fixed. There are nails and other debris in the roads all the time. When we first moved to our current address, my wife had all four of her tires go flat within the first year. I didn't own a car until two years ago, but both front tires have gotten nails in them already. That's also on top of the city's contracted out private dump truck crushing my rear windshield and smashing the hatch and leaving a business card with a claim number on one of my front wiper blades. That was nice to walk out to.

Then there was the crew across the street stealing all of my power tools when I accidentally left my garage open one day.

I'm not a NIMBY, but experiencing this makes me weary of the Hacker News zeitgeist railing against communities that don't want their neighborhoods turned into constant construction. There are entirely non-evil reasons homeowners might want that because building where people already live is incredibly disruptive.

In New York, companies doing road work are required to leave a small plastic circle embedded in their patch that can be used to identify who did the work. They seem to most often be blue though I’m not sure the color is a requirement. Once you see it, you’ll notice them everywhere.

It's kind of maddening how often blogs like this will make motions towards developing an educated opinion (citing multiple reports, researching stats from public datassets, etc.) but don't seem to have bothered to actually talk to any of the people who are invovled in the practice they describe in their post (in this case, building roads).

bluGill8 hours ago

Rural roads are often unpaved. The local authority has to come by regularly with a grade to redo things or they become unusable quickly. Overall this is by far the cheapest way to have a road, but it doesn't scale to high use and city folks demand something that makes less dust. Rural roads also includes minimum maintance roads which demand 4wd (real 4wd, many SUVs will have trouble) when the weather is nice and a winch is a must when things get rainy or snowy.

Though given his definition of quality I expect he is actually ignoring all the real rural roads and only talking about major roads which while they get less traffic than urban roads are maintained to similar standards.

> Rural roads are often unpaved.

Like the other replies have indicated, I'm not so sure this is the case? I live in very rural northwest Iowa, and while there are certainly plenty of gravel roads around here, I'm only driving on them if I'm intentionally trying to go "off the beaten path." You'll take a gravel road if you live on a farm, or you're trying to get to somewhere secluded such as a lake, campground or maybe a county park; but (imo) it's rare for the average person to drive down a gravel road just going from Point A to Point B on their daily commute.

bluGill6 hours ago

I'm not sure we disagree. You use the gravel rural roads to get to the nearest paved road. So rarely are you going more than a few miles on gravel, then you hit a paved road which you travel for the many miles to where you are going. Most of the roads are still unpaved, but you spend most of your driving time on the paved roads.

Yeah I definitely agree with that. I imagine if you were to look at my county's roads from a satellite, it'd be something like the (grid-shaped) veins of a leaf — the thick, prominent veins are the paved roads, providing the structure, while the thinner, branching veins are the gravel roads that run between them.

Montana here. Most of the dirt roads (county roads) have been paved in the 25 years I've been here however there are some left where you can drive 20 miles unpaved. Also recently in Iceland I found a few unpaved roads (or rather "the Google Lady" did. Sorry whichever rental company I used there..

Do most people in rural areas not live on a farm? Excuse my ignorance but genuine question.

bluGill5 hours ago

That is a tricky question to answer. Farms need small towns scattered all over - that is where many of the teachers, accountants, mechanics, hired hands, other services, and owners of the stores that serve all of the above live. Often small towns have factories that are not farm related and those employees live someplace. Do you count those small towns as rural? Many of the above have also realized that they can buy some build a house on marginal farmland cheap and so live rural but they are working a small town job - they may have a few goats or something but it isn't how they earn their money - hard they farmers? There are also people who retire to the country, hunting cabins (not residents), camp grounds (the owner lives there), and other non-farmers living in rural areas. Parents generally transfer the farm to the kid who will inherit it over decades, and part of that is the parents move to a small house off the farm but still rural - are they living on a farm?

Depending on how you count the above you can say that most people in rural areas are not living on farms. Even if you don't count small towns residents, there are a lot of people who are not farmers living out there.

I don't have any real numbers to back this up, but I don't think so. Even in my quite rural area, most people live in towns despite the relatively vast, open farmland. My town's population is between 3-4000 people, but some are as small as 500. It'd take a lot of farms to spread all the people in my town out.

In my area the rural roads are typically asphalt. This part of the country receives a lot of precipitation and cold weather and our soils are pretty soft.

They stay in good shape for years, with little maintenance. There aren't many patches because there aren't many utilities. Truck traffic tends to gravitate to the highways, and car and ag traffic are low impact.

rwiggins8 hours ago

Maybe area-dependent? I grew up in an extraordinarily rural area in Tennessee. Most roads were paved (asphalt). Even ones out in the middle of nowhere.

The conditions of some of the remote roads might not have been great, mind you... and some seemed "thinner" almost, maybe paved a long time ago?

wnc31417 hours ago

Of course there are political factors. I have always heard that in Wisconsin many rural roads were paved to better serve dairy farmers beginning in the 1890s - and continued through the WPA program. While in Minnesota, similar rural roads remained unpaved.

Best link I could find to substantiate such a claim

https://www.uwlax.edu/currents/biking-in-the-driftless-regio....

Of course in contemporary times the high maintenance cost has many Wisconsin towns/counties considering returning to gravel.

I think it's a snow thing - asphalt seems to wear down really fast in rural PA, probably from freezing at nights and snow and ice, so you can't do paving as cheaply out in the mountains or so on. The county dumps gravel down once a year and let's passing traffic wear it smoother over time, but it sucks to drive on fresh.

A lot of that is the road profile. Western NY has notably better county highways than PA because they tend to have wide shoulders that mitigate plow damage and frost heaving on the he edges.

shkkmo6 hours ago

Absolutely. The freeze thaw cycle is brutal on asphalt in many ways. Surface cracks expand, frost heaves distort and the material itself weakens. This is before any additional damage caused by plowing or ice scraping.

Rural around here in the PNW, the vast majority of rural roads are paved, except for forest service roads and the odd road here or there. I do a lot of countryside cycling and it's rare that I encounter a gravel road.

What they don't always have is the smooth surface found on highways; it's paved but of a bit of a rougher type (don't know all the technical differences, but it's noticeable on a road bike).

At the very beginning he separates into:

You're probably also going to have far fewer massive vehicles on those rural roads. More things like pickups yes, but probably considerably fewer semi-teicks and busses and fire trucks and cement mixers what not. Those big trucks passing through are going to stick to interstates far more often when going through rural areas.

This is a reason why buses are not as cheap as they seem at first glance.

Often times, buses are favored because they require low capex (adding lines is easy, politically palatable, etc).

But in practice, on really busy bus lines with high throughput, it shreds the roads, to the point where you really need to re-pave the whole road every 10 years -- in which case, why not just put a rail line in and use a train!

In the mid-90s, Seattle started excavating its bus-stops-on-a-slope and pouring a new concrete foundation, because the busses were warping the asphalt so badly.

I was just back there this last weekend, and you can no longer see any of the concrete - it has all been coated with asphalt. However, I assume its a rather thin layer because none of the bus stops I checked show the signs of damage that were becoming common in 90-96.

We have large farm machinery though.

jgeada7 hours ago

Large machinery, but typically very low ground pressure. After all, that same machinery is designed to operate on arable soil without sinking or bogging down. It is my understanding that it is ground pressure more than absolute weight that correlates to road surface damage/erosion.

potato37328423 hours ago

At some point axle load starts mattering more than ground pressure because whatever's below the pavement itself starts being extruded. I don't think that matters in most cases though.

amatecha5 hours ago

tcmart147 hours ago

There is large machinery. But does it go down the same stretch of road 20 times a day all days of the year though? May also depend on location. You ain't taking the combine down the road several times a day in the middle of winter. So you do get the wear and tear of large farm equipment, but its still probably less than an urban road and not year round.

My grandma used to live close to a road servicing an oil derrick, back in 90's Romania (so 0 infrastructure investments for probably 10 years).

At one point my family was in a Dacia 1310 (crappy and very cheap Romanian car) and we literally went very slowly (probably 10kmph) through a section where the road was basically sunk, there was a "pothole" probably 10-15m long and 80% of the road wide (both lanes), about 1m deep, I think.

The funny thing is that there were potholes inside the uber-pothole :-)))

They put in new pavement in my neighborhood explicitly to fix some sewer issues. They ended up redoing several sections as the contractors paved over 3 access points (manhole covers). I'm not sure how you pave over a man-hole cover when it's sticking up 6 inches from the rest of the street.

amanaplanacanal5 hours ago

Part of it is funding. Highways are for the most part federally funded, and the feds can print money at will. Urban roads have to be repaired from the city budget, and user fees (fuel taxes) are nowhere near enough to keep them maintained properly.

leetcrew5 hours ago

I thought the feds pay a large portion of construction but the states pay most of the maintenance. some states clearly do a worse job of highway maintenance than others. it's like night and day crossing the MD/PA border on I-95.

salynchnew3 hours ago

Hence why U.S. roads are not built to last in the long term.

Spooky233 hours ago

That’s part of the reason. The other is that rural roads are mostly county or state funded (often through large Federal appropriations), and draw in a larger tax base and in-house professional engineering.

That’s why you can drive around rust belt areas of Upstate NY on nice roads - NYC Finance bonuses pay for that.

City roads are usually maintained by the city, which has much more limited access to capital. Because of that, in-house work is usually limited to mill and pave work and there’s not enough throughput for an appropriate staff of engineers. Big projects are usually task focus (safety, multi-modal) and are funded by Federal grants and use outside design and build contractors.

For the shared utility work, there is some coordination. My wife worked for a municipal water utility and ran the metering and infrastructure division. They received notice of paving or other jobs and prioritized proactive maintenance to happen while the road was under construction. The city would fine entities for digging up the street for non-emergency purposes for 6-12 months after the project completed. It helps, but broken mains or transformers necessitate the street cut.

potato37328423 hours ago

This trope that rich cities pay for everything needs to be taken out and shot. Yes, there is a cash flow there but it's nickels or dimes on the dollar, not a huge amount compared to variances in budget and expenditures. Buffalo would not turn into Mogadishu without NYC paying for the privilege of ordering it around by proxy of Albany.

My favorite are the leaky man hole and other infrastructure covers which allow rain to wash the road bed into the pit. Then a void forms and a pothole forms. Then the muni fills the hole only for it to reappear as more road bed is washed away. Then repeat ad nauseam. I sometimes imagine a snake of asphalt all the way to the sewer plant.

jameshart11 hours ago

This is a great analysis but it does focus exclusively on ‘roughness’, which is obviously important but isn’t the be-all-end-all of road quality.

One area I notice in particular that roads in the northeast US subjectively feel worse than Europe is in quality of road markings. Constant plow scraping and harsh salting seems to destroy markings.

I think it also shows up in the overall fit and finish of road infrastructure - edging and barriers, signage, lighting, maintenance of medians, how curbs and furniture contribute to junction legibility… and of course bridges.

One major reason is that European countries typically have national road agencies and consistent standards across the country (because, generally, smaller and less federal). US’s patchwork of federal, state and local road maintenance leads to vastly different budgets and department priorities across the network.

CoopaTroopa9 hours ago

You have a good point. I live in Michigan and recently traveled down to Austin, Texas. The roads didn't seem all that much better but all of the road markings really stuck out to me. Reflectors in all the lines separating lanes, soft bollards surrounding cross walks and parking areas, extra curbs built in for bike lanes. It makes things look a lot nicer but my first thought was, "could you imagine trying to plow around those bollards, or those reflectors would get ripped up on the first pass."

Etheryte6 hours ago

Northern Europe gets more than enough snow and bollards and reflectors are a thing all the same. It's not a problem if you plan for it ahead of time and design and build things with that in mind.

Austin didn't even have snow plows until 2022, the year after snowmageddon. If I remember correctly, they tried using road graders and sand. Even then, it's generally ice, not snow in central tx, even after removing snow in 2021 there isn't/wasn't much to do about all the ice.

Just FYI, at least germanies rods are also a patchwork. E.g. there are the Autobahns, which are financed by the federal state. Than there are Bundesstraßen (Yellow markings, typically something like B56) which are also financed by the federal state.

Then there are Landstraßen, which are financed by the Bundesland (state, LXXX). Followed by Kreisstraßen, financed by the Gemeinde (county?`).

Finally there are Gemeindestraßen, financed by the city or town.

There are lots of norms and regulations on how to build these roads, so there is not that much variance except layout. E.g. a bike friendly city like Münster has a dfiferent layout than say Cologne.

I think your last paragraph is the key one. AFAIK in the US a lot less is regulated on a federal level. Like in Oregon you'll rarely see reflectors on the lane markings whereas they are omnipresent in some other states.

The reflectivity of the road markings in North Carolina—where plows are rarely used—is terrible, to the point that they are almost invisible on a rainy night, even on freshly painted roads. It's the worst of anywhere I've lived or driven in the U.S.

Relatedly, recently my wife mentioned seeing a vehicle with large boxes on each side and wondering what they were. From her description, I tracked down that they are a fleet maintained by a small company that measures road marking reflectivity:

So who knows, maybe NC is finally doing something about the road markings here.

sumtechguy8 hours ago

In NC it really depends on where you live. With some of them looking very nice. While others it looks like it has not been touched in 20 years. I personally think they just have a set timeframe to refresh things and they stick rigidly to that no matter how good or bad they are.

js26 hours ago

I've driven NC from the mountains to the sea and haven't seen good reflective markings anywhere. Certainly all the road markings in and around Wake county are awful. Even at their best the markings don't compare to say Florida roads.

I think part of the problem is that NC counties don't maintain their own roads:

"North Carolina has the second largest state maintained highway network in the United States because all roads in North Carolina are maintained by either municipalities or the state."

I think NCDOT just doesn't use reflective paint. Maybe it's more expensive. I see folks complain about it frequently.

Same in Italy (and probably most other EU countries); there's (about 25.000km of) roads that are maintained by a state agency; others are managed by a region, a province or a city. There's also an entirely different agency that needs to take care of highways.

Yeah the UK is pretty similar. Devolution means Scotland and to a lesser extent Northern Ireland have some autonomy, but the big important roads are controlled by national government (albeit not necessarily the UK government) and your residential street is handled by much more local government, in my case the city where I live.

Actually Scotland bizarrely happens to have a road most similar to what most US folks would consider normal - a motorway (a multi-lane highway) named M8 going straight into the centre of a large city (Glasgow) on concrete stilts. This is not how the rest of the UK does it, but it so happens the M8 was conceived in that window of time where it was considered a good idea, some parts of my city were made in that era and I'm glad I don't live in them.

> focus exclusively on ‘roughness’

also, as a road cyclist I've found that there are different types of paved roads, some are very smooth (asphalt I presume), and others are less so (concrete?). Both are paved, but one is much more pleasant to ride on than the other. I don't know if there is a relationship between roughness and durability or quality, or those are just different techniques.

miles_matthias3 hours ago

Well then there's the overall experience using the roads, regardless of roughness. For example, Texas' under interstate turnarounds are super weird and make running a local errand feel like a cross country trip as an example. Areas without zoning laws between commercial / residential feel more stressful to me as a driver personally too.

mannykannot10 hours ago

While I agree on your additional criteria, I feel the roughness metric itself (at least as explained here) is not as informative as it could be: a generally smooth road surface with sudden discontinuities in level (e.g.potholes) seems qualitatively worse (and damaging) than would be a smoothly-varying one with the same roughness. Perhaps an alternative metric might be based on the maximum speed at which a typical car or truck could travel without experiencing vertical accelerations above a certain threshold? ('typical', here would be with regard to things like its mass, suspension travel and stiffness, and wheelbase.)

wubrr9 hours ago

The metric might already account for the scenario you bring up, since a road with potholes will be more 'rough' than a smoothly varying one based on my understanding of this metric.

mannykannot8 hours ago

I thought about that, but this is what I had in mind: take a section (say 100 M) of an undulating road, smooth it out, then put a ridge across it that restores its roughness to its initial value. My feeling is that the latter would be more of a problem (this opinion is colored by the fact that, in my neighborhood, road repair is creating bumps and ridges like this.)

wubrr7 hours ago

I guess it would depend on how big the ridge you add would have to be. I'm not at all an expert on this, but my thinking is that a ridge of size 2X would have an exponential effect on the travel of the suspension and resulting IRI value when compared to a ridge of size X. So a perfectly smooth road with a ridge of height 2X would have a higher IRI than the same road with 2 ridges of size X.

The wikipedia article has more details on how the measurements are done (there are multiple different ways/instruments used which can have different results) - https://en.wikipedia.org/wiki/International_roughness_index

> The IRI is based on the concept of a 'golden car' whose suspension properties are known. The IRI is calculated by simulating the response of this 'golden car' to the road profile. In the simulation, the simulated vehicle speed is 80 km/h (49.7 mi/h). The properties of the 'golden car' were selected in earlier research[12] to provide high correlation with the ride response of a wide range of automobiles that might be instrumented to measure a slope statistic (m/km).

I've driven in France, Iberia, and Central/near Eastern Europe (Stuttgart to Budapest, Krakow, and back). City streets can be small, but the highways are highways. Even smaller roads in Slovakia weren't bad. Honestly didn't seem that different from driving in the US except that obedience to speed limits was a lot higher (though their limits are generally higher, so there's no real need to speed - 130 km/h is just over 80 mph, which is usually as fast as I would want to drive anyway).

Yeah in Europe you want to head for the main train stations or Park and Rides if you're spending time in cities. They usually have large car parks and good public transport.

Outside of towns and cities the road networks in those countries are generally excellent. Especially in France and Italy with their toll roads.

If you're just going city to city, take the train.

I've driven extensively in Spain and to a lesser extent France, Italy and Germany and never found parking a "joke" except in cities or with a huge car. Of course, due to density, the free parking places are usually very busy and hectic. But there's always an option to pay/pay more

> Interestingly, I expected cold places to have lower road quality in general due to things like freeze-thaw cycles and the impact of road salting, but there doesn’t seem to be much correlation. Plenty of cold places (North Dakota, Wyoming, Minnesota) have good-quality roads

Not sure about those states in particular, but I have anecdotally noticed that some of the places with the harshest winters do some of the least road salting -- because salt is mostly usable for light to moderate snowfall and the people who live in the harshest climates are often better equipped to drive on hard packed snow.

alwayslikethis8 hours ago

The more obvious reason is that colder places do not get as many freeze-thaw cycles. It simply stays frozen for a few months. In contrast, much of the northeast experiences many more freeze-thaw cycles since even in the winter it is warm enough to thaw the ice on some days.

Cold places see a lot of freeze-thaw cycles in fall and spring - before and after the hard freeze. I don't know how they compare, but it isn't clear cut.

> Not sure about those states in particular, but I have anecdotally noticed that some of the places with the harshest winters do some of the least road salting

Salt isn't effective when it gets really cold so it tends to be applied more around freezing as opposed to below. It also depends on the road surface temperature as well, heat of the sun melts off snow and that freezes at night. So you'll find salt has to be applied intelligently to the conditions, on bridges for example, which I suppose would come from experience.

I also observe southern states seem to use more rubber instead of rock in their road surface. So that might be a factor on how robust they are to wear.

bluGill8 hours ago

0F is defined as the temperature that salt on ice reaches. Regular salt is used a lot in Minnesota because it works fine most of the time and is cheap. It doesn't work on the coldest days, so about 15F they start adding in salts other than NaCl. Below -15F they no longer have a salt that works at all - but those days are rare.

My Grandpa worked for the MN highway department until around 1995 when he retied, so my information is a bit out of date, but chemistry doesn't change that much so I doubt it is very different today.

This is somewhat true where I’m at in Canada. In the city, half the people have proper winter tires, the other half “wing it” with whatever they can afford/put-up-with.

Regularly see accidents all winter long from goofs sliding straight across multiple lanes of traffic or going off into the ditch. Only some of us are prepared.

We don’t salt, only drop sand grit and gravel sparingly. Our roads become ice rinks or snow piles for a decent portion of the winter.

Your comment about us being “better equipped” made me chuckle as I spent this morning watching my neighbours play slip-and-slide in the cul-de-sac cause they opted to not put their winter tires on.

As someone who grew up in the mountains, their behaviour is downright dangerous in my opinion.

Not sure when snow tires became more mainstream but I started driving in Michigan in the late 80s and didn't know a single family that used snow tires. Where I live now snow tires only make sense for those who live in or visit the mountains regularly. The valleys are mostly at or above temps where snow tires wear quickly or become less effective on wet surfaces.

devilbunny2 hours ago

I live in the southeastern US. I am aware that winter tires exist, but you simply can't buy them here off the rack. You have to order them. For our "snow", which happens once every 2-3 years, you don't even need them. In an ice storm, you just stay off the roads for two days. The heat from the sun is sufficient to melt it even if the air temperature never gets above freezing.

What you need here are tires that can handle huge amounts of rain. Which, in the western US, is not an issue.

Winter tires are not cheap. I'm in Alaska and recently paid $1400 for a new set of studded winter tires for my F-150. And the tires I chose were one of the lower cost options available.

So I totally understand why folks who can barely afford to put gas in their car are driving around on all-seasons year round (and ending up in the ditch frequently).

Very much so - WI and other northern states know how to clear their roads. While you will need to slow down a little more while it is snowing it doesn't really matter because someone else will not have winter tires and so force you to slow down to that speed even if you have them. And even if you have them they are better than summer tires, but they are not that much better, you still need to slow down on ice.

Winter tires are very important in places where they get bad weather but don't clear the roads. Those are not generally places people live though.

Perhaps more important - salt's effectiveness fades as the temperature decreases. Sand and gravel do not have that problem. So if you're running the Road Dept. in an area where serious cold ain't some rare event - why would you bother with salt?

EDIT: I know the "melt to pavement, solar heating finishes the job" tactic. Which can work with heavier snowfall, if you plow/shovel before salting. Colder weather inhibits both halves of the melt-&-heat. (Plus the further north you are, the shorter & slantier the sun's rays get, even on clear days.)

DCH341610 hours ago

Because the goal is to get the road surface exposed so it'll heat up and melt off the snow during the day. And then the residual salt will leave a residue which will help prevent refreezing.

kube-system9 hours ago

That only works in places with relatively milder winter climates. In harsher climates, salt stops melting snow, and the surface temperature of even exposed road may stay below freezing even during the day.

DCH34169 hours ago

Yeah. I'm familiar with the harsher climates aspect.

The salt isn't really for the snow, it's for ice. Temperatures above like 10F, the sun will still cut through an untreated road surface and glaze over. Even with snow, because the top layer will still freeze, that nice crunch you get. The hazard is you have a smooth surface that your tires can't grip onto well when the sun goes down. I know it sounds counter intuitive but snow will still melt on very cold days because without wind you get a localized heating effect from the sun.

The nice thing is, ice gets increasingly grippy the further down you go. It's the around freezing temps that get you. And bridges since rather than the ground holding temperatures, now you've got an air conditioning going on under the road. That's why salt is so useful over say grit because it changes the freezing point of the water.

There is more than one kind of quality.

When I drove from New Mexico from New Hampshire I thought roads in the US South were remarkably good. I settled in New York where major roads seemed pretty good but go to Pennsylvania and it seems there are two kinds of roads: bad roads and roads under construction, you never seem to find a good road that was just constructed. A lot of people thought it was frost heaves but this article say it isn’t.

My quality problem in NY is that atlas maps and GPS maps show numerous roads that aren’t really passable or if they are passable are too risky. I never saw ‘minimum maintenance’ or ‘abandoned’ roads before I came to NY and I wish they were so marked in GPS maps. There is a road near me which is sometimes passable in the winter if you have the right kind of vehicle and if you know the road goes downhill and won’t require that much traction… People who don’t have the right kind of vehicle will get led by GPS down this road and think it is OK because there are tracks but halfway through they panic and try to turn around now they are in trouble. That road is passable in the summer except for when it gets washed out.

Also NH is in a class by itself with its motor-oriented infrastructure (in 1980 they rerouted route 93 to go around Manchester and nobody goes there anymore) which is tree-structured as much as possible so you have many levels of hierarchy which can and will jam up. Want to walk? You can’t get there from here. I can go for years in NY without updating my GPS maps but if I drive to NH I will see the road I am got rerouted and there is a shopping center where there used to be a road. And this is in a state that doesn’t have income taxes so I don’t know how they pay for it.

I say this as someone who owns an EV; I should have to account for the higher road deterioration my heavier vehicle causes. If someone's income is too low you fix that other ways than trying to subsidize their externalizing behaviors.

Oregon has tried to implement a miles tax multiple times but failed to pass it. Instead they've opted for a surcharge on vehicle registrations for EVs and also on any vehicle that gets better than 20 mpg.

Counterproductive from a climate change standpoint for a "green" state but it preserved the road money.

surfaceofthesun5 hours ago

I think a miles traveled tax that accounts for vehicle weight would probably less regressive than the current gas tax.

EVs save substantially in running costs. I’d imagine it would charge those using 3/4 and 1-ton pickups as family cars the most.

People being too poor is a separate issue from bad tax systems incentivizing unsustainable behavior.

Tax liabilities that are a function of consumption are the right way to tax.

If the tax burden is deemed too high for poor people, then give them cash.

Two different problems, two different solutions, and it keeps the incentives aligned properly.

I'm from South Carolina, pretty close to the border with North Carolina. All my life i've heard that South Carolina's roads are terrible, especially compared to North Carolina's _amazing_ roads.

Looking at this data though, it seems while NC edges out SC by a small margin on interstate roads, SC actually beats NC on local roads.

Take that, North Carolina!

How does Hawaii have interstates?

kube-system9 hours ago

Because "interstate" doesn't refer to the function of the particular road, it refers to the federal program that created them: the "Dwight D. Eisenhower National System of Interstate and Defense Highways".

There are a ton of interstate highways which do not go between states, even in the continental US, and especially the auxiliary (i.e. 3-digit) interstate highways: https://en.wikipedia.org/wiki/List_of_auxiliary_Interstate_H...

The US already previously had (and still has), a national road system that traversed across states other than the Eisenhower system. But nobody calls these roads "interstate" because they're not in the Eisenhower system: https://en.wikipedia.org/wiki/United_States_Numbered_Highway...

"Interstate" has always specifically referred to Eisenhower system roads only.

I watched this YT video [1] about the interstate system recently, I found it informative and entertaining

To me, the Eisenhower Tunnel in CO [2] is noteworthy. It crosses the continental divide at altitude. From what I've read and watched, they don't allow HAZMAT trucks to go through, because the risk is simply too high (well equipped fire/rescue departments are hours away, among other factors)

Anecdotally, it seems like a ton of projects got started as a result of this bill, but it doesn't seem like many of them are getting worked on or finished.

A good comparison point would be Germany. It has a very large network of roads too, some designed for very high speeds, and a strong driving culture (perhaps stronger than the continental US).

I'm an American, I lived in Germany for several years around the turn of the century. German roads that I encountered were far superior to American roads. Their construction is far more robust, the roads last much longer. And with German lane discipline (passing someone on the right is practically a cultural taboo, it's a prohibition that's taken quite seriously) they are usually a joy to drive on.

PaulDavisThe1st6 hours ago

I found the autobahn utterly nerve-wracking to drive on.

In the US, on an interstate, the MPH spread around the speed limit is probably -20 to +20 (i.e. limit is 75, slowest cars are at 55, fastest at 95)

In Germany, on autobahns, you have speed ratios of up to 2x. You have to constantly be 110% aware of every vehicle within 1/4 mile of you, because you could either be closing in the much slower vehicle in front of you, or suddenly approached and passed by a much faster vehicle from behind.

bluGill10 hours ago

I'm guessing not maintained. Minneapolis is forced to spend a lot more on roads just to keep things acceptable. They also have a lot of voters with a memory of how bad things get after a bad winter and so politicians don't dare short road funding let they be voted out over a few potholes. (I've seen roads in Minneapolis that were more pothole than surface)

Maintenence. I grew up in the north (Michigan) and spent time in Massachusetts, living in Texas now it's very different how infrastructure is funded. I'd call it a result of the general politics, no one wants to spend money on infrastructure.

I believe the latest stat I heard was that over 70% of the roads & alleys in the city where I live are >40 years old. That also means all of the infrastructure under the roads (water, conduits, etc.) are also >40 years old.

My grandpa used to work for the MN highway department. That isn't a joke, it was reality for them. Either the plows are on the truck and they are plowing snow, or the plows are not on and they are fixing roads.

Roads are a tiny % of any government budget. St Paul could have the money to do more if they wanted, and it wouldn't be much of a total budget increase. However it would still increase taxes and so people should debate if it is worth the cost.

Some of that won't translate as well to road quality due to the fixed cost portion of road repair (because the OPM rate isn't the highest (though still quite high)), but some of it will due to the not fixed cost portion (labor, etc).

But it definitely affects prioritization. People won't care as much about road quality relative to other things.

This is insane. This just proves how entrenched this country is in car centric transportation. We spend trillions in building, subsidizing, and maintaining this infrastructure. Only for this cycle to repeat itself in 25 years as the roads/highways breakdown and people move further out (induced demand). Then there’s the billions in lost productivity due to traffic. Significant decrease in activity and increase in obesity.

Then the increased emissions from vehicles result in poor air quality. Then there is decreasing water and food quality as tire and brake particles make its way into the water and food supplies.

You're right that car centric transportation is entrenched, but this is the wrong statistic to prove that point. The US is a huge country and the overall density of roads (km/100km2) is lower than Europe.

For your critique, you'd want to break out urban+suburban road networks from regional and rural ones. The US was a frontier country that grew on top of continent-spanning trails with pockets of community cropping up everywhere there were agricultural, material, or strategic resources, or the need for a travel rest. It's to be expected that we have many miles of road and mostly a good thing that our communities are so well-connected and traversable.

It's what happens inside those communities, when they could be designed with better concern for local community or sustainability, that warrants the critique. And it's a good and fair critique. Just not one directly spoken to by the quoted statistic.

Couldn’t driving more be a sign of a strong and productive economy? Other large countries like Russia or Australia or something that drive less have smaller GFP as well.

Can we make a better comparison of how much Americans drive, plus total travel, vs total travel for other countries of similar density and size?

PittleyDunkin10 hours ago

I imagine you'd have to weigh this against alternative forms of transit. The freight rail industry is the largest in the world and directly represents (presumably productive) economic activity. Personal transit makes up a much larger percentage of road usage, even in metro areas with healthy public transit. It's hard not to see this as some form of inefficiency.
