transportation planners in the United States are beginning to borrow an idea that's common in Europe to make the freeway corridor more livable: see-through sound walls.

@Chris: you're forgetting the A12 near Arnhem. Though that one is quite annoying. If the sun is standing on a wrong position you can get blinded by the reflection of it. (don't know whether these problems are elsewhere too?)

Which makes sense, you wouldn't expect to see a lot of extremely large freeways given just how many highways dot the La landscape.

This is funny, because LA doesn't have a large freeway system at all, counted to population. I did some research myself, and when counting to the number of residents per kilometer (or mile) of freeway, LA has about 11.890 inhabitants per kilometer freeway.

My list isn't finished by far yet, but i can already tell, that metropolitan areas like San Francisco Bay, San Diego, Denver, Jacksonville, Orlando, Tampa Bay, Baltimore have a much smaller share of people using 1 mile of freeway.

Metropolitan Orlando for instance, has 5.890 inhabitants per kilometer freeway. Denver has 6.691 inhabitants per kilometer freeway.

SoCal freeways are way out of this world but Atlanta GA freeways are totally wide especially the downtown freeway (I75-I85). I think its like 12 - 14 lanes. I went there last week and its way too cool at night (no traffic) but in the morning, it was a nightmare of traffic jam.

Not only that, concrete makes a great base for asphalt, i think most of the O.C. toll roads are asphalt, thru the cuts and fill areas, all the bridges are concrete, of course. ........to save costs.!!!

I wonder if they ever widen I-405 to 14 lane perhaps. The traffic is way too ridiculous.

What do you mean? to put asphalt on top of the concrete surface when it starts getting rough?
We do that in Portugal sometimes on your few concrete motorway stretches. But I guess that's mainly because the concrete surface was getting bad.

Well, there are actually only 2 routes from the southeastern suburbs to Downtown; the I-5 and I-405, serving millions. Almost the entire population of Orange County (3.098.121) has to use the Santa Ana or San Diego Freeways at some point to reach Los Angeles.

The 405 has a 390.000 AADT on only 2x6 lanes to 2x7 lanes (theoretical capacity 288.000 / 336.000)! That's pretty crazy between the Garden Grove & San Gabriel River Freeways.

To handle that much traffic properly, you need 2x9 lanes for that amount of traffic. However, 9 lanes are highly impractical, so a different route is better. However, this area is densely populated, with backyards immediatly to the emergency lanes.

Rail-based mass transit only reaches Long Beach and Norwalk, so that's not an alternative either. Maybe they should extend some lines to the Santa Ana/Irvine region. It wouldn't solve everything, but it might be able to handle some of the growth in that region.

20 years, ago, Irvine was the most southern suburb. Now, there are already about 11 new suburbs totalling 531.000 residents, most of them living closer to San Diego then Los Angeles.

A better analysis would divide inhabitants by (expressway miles * lanes).
