How good are American roads?
American road quality varies sharply: interstate highways are generally smooth and well-maintained, while urban streets—especially in large cities like Los Angeles and San Francisco—are often riddled with potholes, poor markings, and patchwork repairs. Commenters tie these gaps to governance and funding structures, regional politics, climate, vehicle weight, and constant utility work under city streets, noting that cold regions like Minnesota or New Hampshire can outperform warmer states such as California. Many compare U.S. roads unfavorably with parts of Europe and Canada, and several argue that America’s car-centric transport model amplifies the economic, environmental, and safety costs of subpar infrastructure.
Road dust, metals, and weird “urban mining”
- Some mention road dust being unusually rich in platinum-group metals from catalytic converters and brake/tire wear.
- Small-scale experiments and anecdotes (e.g., shop-vacuuming freeway shoulders) suggest you can recover metal, but it appears uneconomic at normal scales.
- Parallels drawn to sewer “gold panning” in jewelry districts: technically real, but marginal returns.
Car-centricity and what “4.3M miles of road” means
- Large US network size is seen by some as evidence of entrenched car dependence, induced demand, and associated health/emissions costs.
- Others argue raw miles are misleading: the US is big, rich, sparsely populated; road density and usage mix (personal vs freight, rail vs road) matter.
- Several commenters say the real critique should target urban/suburban design, not the mere existence of many rural roads.
How road quality is measured and felt
- The article’s focus on “roughness” (IRI) is welcomed but seen as incomplete; people care also about lane markings, reflectivity, signage, drainage, and junction design.
- Night-time/rain driving highlights huge differences in marking quality between states and even counties.
- Some note that potholes and sharp discontinuities feel worse than what a single averaged “roughness” number captures, though others point out IRI already simulates a “golden car” suspension response.
Climate, winter practices, and salting
- Thread challenges the simple “cold = bad roads” story: cold states like Minnesota and North Dakota can have good roads, while warm places (California, Texas) often don’t.
- Explanations offered:
- Freeze–thaw cycles matter more than just low temperatures.
- Salt is only effective in certain temperature ranges and can destroy both roads and vehicles.
- Very cold or snowy regions sometimes salt less, plow more, or rely on sand/gravel.
- Canada and northern US see very different practices across provinces/states; some ban or minimize salt, others “brine the pavement”.
Regional and urban–rural disparities
- Strong perception of state-to-state contrasts: e.g., dramatic transitions at borders (Kansas–Colorado, Maryland–Pennsylvania, Arizona–California).
- Interstates are often praised while large-city streets (LA, SF, Dallas, Boston, Philly, Atlanta, etc.) are described as awful.
- Intra-metro gaps are big: affluent suburbs often have much better pavement and markings than poorer neighborhoods in the same region.
- Rural paved roads can be surprisingly good where traffic is light and there’s little underground utility work; truly unpaved or minimum-maintenance roads are a separate, often ignored category.
Governance, funding, and standards
- US patchwork (federal/state/county/city) leads to uneven standards and budgets; some places have sophisticated monitoring and tight maintenance cycles, others defer work for decades.
- Examples from Germany, UK, Italy and Scandinavia: similar multi-level governance, but more uniform technical standards; some EU-wide norms exist, though local variation remains.
- In US, choice of paint, reflectors, and lane design can vary widely by state DOT; some states appear to prioritize low cost over reflectivity or durability.
Underground utilities and road degradation
- Many argue that urban roads are rough less because of traffic volume and more because they are constantly cut open for gas, water, sewer, telecom, and then poorly patched.
- Repeated patching with mismatched materials, leaky manholes, and uncoordinated utility work accelerate potholes and settlement.
- Some cities try to coordinate: notifying utilities before big repaving projects or penalizing non-emergency cuts soon after resurfacing; effectiveness is mixed.
- Utility tunnels are proposed as an ideal solution in dense cores, but commenters note they’re extremely expensive and only plausible in limited areas or new-build cities.
Taxes, EVs, and how to pay for roads
- Several US states debate mileage-based road charges, partly to replace shrinking fuel-tax revenue from high-MPG and EV vehicles.
- Concerns: regressivity for poorer and fixed-income drivers; privacy and rent-seeking around GPS-based tracking schemes.
- Some prefer simple odometer-based systems; others push for weight×miles pricing to reflect actual wear, arguing that income-support should be handled separately from usage pricing.
- Registration surcharges on EVs and very efficient cars are cited as a common but climate-unfriendly stopgap.
Comparisons beyond the US
- Many personal reports say German and some other European highways feel vastly smoother and more consistent than US roads; lane discipline and intersection design also differ.
- Others note European city driving can feel stressful due to narrow streets and constrained parking but see that as a tradeoff for walkability and transit.
- Cross-border anecdotes (US–Canada, US–EU) often mention stark changes in smoothness, snow treatment, or maintenance style at national or provincial borders.
Meta: data vs perception
- Commenters appreciate the article’s data-driven approach but note that lived experience—noise, safety, legibility, driver behavior—often diverges from simple IRI scores.
- Some suggest weighting quality by vehicle miles traveled or population served rather than road-miles, which would likely make major metros look worse.
