It was a republican who voiced that, not a democrat. The Democrats were the ones who gave speed limit control to states in the 1990s.

Well, last year the Swedish road agency Vägverket got fed up with all the Russian buses from the 70s that had no diesel particle filters (a requirement in the law here) and so the police forbade the buses from going anywhere. They had to be towed to the ferries as they were not allowed to run on Swedish territory. :p: However this was the only time this was ever done, you still see tons of buses (and trucks) all the time. It was just to make a statement, I suppose.

Well it does move a lot faster. But it's so strange - so many seem so against it. I was driving not long ago on the Bay Bridge in Maryland near DC and it seemed like 90% of drivers were going through the regular tolls. It was early morning and a huge number of those were surely commuters. So strange that they wouldn't get the pass...

If they really want to conserve gasoline they should

1) Change to more fuel efficient diesel
2) Buy fuel efficient cars
3) Avoid stop-and-go-traffic in cities
4) Resolve some of the worst traffic jams
5) Lower the speed limits for trucks to 50 / 55 mph.
Most cars have the best mpg's between 55 and 65 mph. Also I agree with stop and go traffic as most lights are poorly timed and this doesn't help that case.

I was really impressed with the highways in southern California... the I-5 is great.

With my 150 HP Honda I get 31 mpg at 60 mph and 29 mpg at 80 mph. Doesn't seem much difference to me.

What's really sad is that even with high gas prices, environmental consequences, dependency problems, etc., car commercials in the US still advertise huge cars and then brag about 20mpg or - a few here and there - 30 mpg being absolutely amazing.

My first car years ago before any of these crises started got 45mpg.

The dense grid-network they have in older urban area's in the US isn't really helping fuel economy too... Lots of stop-and-go's. I prefer the 1 by 1 mile grids, so you don't have to stop all the time. You usually see those in newer urban areas.

I-10 is now jammed near New Orleans due to people leaving the city because of Hurricane Gustav.

Maybe we get this kind of pics again:

Most suburban areas are built like that, but once they get more built up, more traffic lights get added to various businesses and shopping plazas that line the main roads. These areas will tend to have about 4-5 traffic lights each mile (maybe more) once they get fully built out.

It must be horrible to live in New Orleans right now. The pic Chris posted says enough.

What do you mean by 1 by 1 mile grids?

The city I leave in, called Bellevue, it's about 10 miles east of Seattle, has city blocks that are 600 feet by 600 feet, (183m by 183m), and those blocks are huge. For pedestrians, those are nightmares, because there is virtually nowhere to cross the street. Paddington's right, those "superblocks" may be there when density is low, but once the development and pedestrian traffic increases, signals will start to pop up.

Picture time. Here's a section of I-90 that is by far the best U.S. road I've traveled on. This is I-90 between milepost 13 and 18.

Road before I-90 on-ramp.










On-ramp









Highway













































Off-Ramp









If you look closely, those are leaves printed into the concrete







Road after off-ramp







Just for fun, some pictures of the major development project going on. It's an "urban village" development with 3000 new homes being built.

Nice pics! Is the I-90 actually at least 2×3 all the way from Boston to Seattle? Even in the remote parts in Montana and South Dakota?

Thanks! No it is not. In Washington, it kind of goes something like this:

starts out 2x4
Milepost 1: 2x3 with a middle reversible 2-lane HOV for about 8 miles
Milepost 8: 2x4 again
Milepost 15: 2x3
Milepost 20+: 2x4

Then past that section when you reach around milepost 50-60 or so, it drops down to a 2x2 for central Washington. In rural areas, there is really no need for a 2x3. I heard that in some areas, it's not even a dual carriageway, although I haven't confirmed it with anyone. I should go check out Google Maps when I have time.

Traffic volumes are extremely low in most of the northern States, sometimes even below 10,000 vehicles/day. Some parts of the I-90 are hundreds of miles away from the nearest place you can actually call a "city".
