Does this include all dual carriageway roads?

No, freeway-grade roads.

Urban areas are defined as areas with a population density of over 1000 inhabitants per square mile, hence it deviates from the MSA definitions.

In that case it seems that Anchorage has quite a lot of freeway miles. Weird.

To put things in perspective. I've just calculated the Dutch Randstad (7.1 million in metro). It would rank between 1 and 2 worst, at 0,260 miles per 1000 inhabitants. This would make the Randstad almost twice as bad as Los Angeles.

I don't trust the "highest 35" list since Wichita isn't in it.

Population: 361,420

Land area: 138 square miles

Mean population density: 2618 persons/square mile

Freeways: I-235 (64 lane miles), I-135 (66 lane miles), US 54-400 (72 lane miles), K-96 (40 lane miles), I-35 Kansas Turnpike (44 lane miles) = 286 lane miles

Freeway lane miles are measured within the city limits (i.e., many will have substantial lane mileage outside the city limits but only lane mileage within Wichita is counted).

Wichita should be right in the middle of the "highest 35" list (0.79 lane miles per 1000 head of population), but is nowhere to be found. (BTW, it has much less traffic congestion than other cities which place higher in terms of lane miles per 1000 head of population, because it has a lower population overall, is geographically more compact, and the freeways are laid out efficiently in a grid.)

No data for Wichita. Odd indeed, since places like Laredo and Pensacola are present. I also miss Des Moines and Knoxville

Not too weird when you consider Anchorage's settlement pattern. It is very sprawled out, with dozens of subdivisions over many square miles having very low lot occupancy rates. There are mountains within the city limits, including one which is a popular hiking park (I tried to scale it in flat-soled shoes and almost broke my head open). As a result of its lack of geographical compactness, Anchorage has a very large land area with a very low population, and has long lengths of the New Seward Highway and the Glenn Highway within its city limits.

Meanwhile, Anchorage suffers greatly from congestion because its arterial system is rudimentary (mostly two-lane when cities of its size in the lower 48 will have four-lane or better), the concentration of businesses in the downtown area results in a traditional in-out commuting pattern with long journeys handled on low-capacity infrastructure, and none of the three freeways interchanges directly with any of the others. (The third freeway is O'Malley Avenue/Minnesota Drive, which functions as an airport connector and interchanges with the New Seward Highway at a signalized diamond.)

This is why the locals cynically call the town "Los Anchorage."

I wonder if the choice of cities for data-gathering purposes is based on estimates of congestion. For example, Kansas City might be chosen while Wichita and Des Moines were ignored, because KC has much worse congestion than both. (I last passed through Knoxville in 1995 and so have no recent information, but at that time it had no congestion to speak of, while Nashville was fast approaching gridlock.)

I think wide medians on freeways are great. I don't want all those headlights right in my face. Plus the U.S. has so much land it doesn't matter how wide the median is.

Look at that beautiful wide-open space.

That's true, if the next parallel Interstate is like 200 miles to the north, it doesn't matter much if the median is 9 feet or 900 feet wide.

True. Plus I think wide medians are great because you can always expand the freeway by filling in part of the median. If there is a narrow median freeway expansion will take a lot more work because exits and overpasses have to be reconfigured.

Aside from that wide medians are just great. I'm surprised to see most of the rest of the world using narrow medians even on new highways.

I consider this a narrow median.

Many motorways around the world have center barriers that are tall enough to prevent headlight glare.

You can read some more about the freeway lane mileage list on my blog (in English);

Sometimes with those tall walls they become annoying because it blocks the view of the landscape on the other side of the highway.

I suppose that could be the case- but I don't think that's all that important when measured against safety standards. If one wants a nice Sunday drive they can exit and take local roads.
