LOL, true!
And don't forget that American cars are overall larger and with some stupid drivers, it is very likely that he/she is occupying two lanes.....

It's not lane occupancy that is a problem. Most traffic jams are caused by illegal or otherwise dangerous lane changes. An illegal lane change causes everybody behind that vehicle, in both lanes, to slam on the brakes. Americans also have bad habits such as passing on the right.

That's Asia's problem. But it is compensated by daring. Drivers in Shanghai pay attention, as opposed to eat and talk on the phone simultaneously while driving. It allows for some very fast reflexes among veteran drivers. By Chinese standards, America doesn't even have veteran drivers outside of New York. We've only been through boot camp, not war.

They might have a couple like Cleveland, but I doubt they have that many. Also, if you take a close look at them they might not even be 4 level stacks.

Of the ones you posted above, look at how horizontally spread out the ramps are. That's to minimize the length of the bridges, and minimize the need for having multiple bridges all flying over eachother. They all look like 3 level interchanges tops.

cool pix, that stack in LA is definitely the most impressive, although that one in Shanghai is pretty sweet.

I think that older stacks are slower but newer ones like the Dallas high 5, the 190(35E, DNT, 75, 635) interchanges, 35W/30 and the BW8 stacks are probably as fast if not faster.

They also have interchanges where the service roads create 5 level stacks. The 635/75 interchange is levelled like

Golden Glades in Miami is an obsolete disaster built back when Florida was still the American equivalent of a third-world country, its government gave thanks daily for Mississippi's existence so it didn't have to be last at anything, and FDOT was insane enough to think having 3 freeways and 2 major highways collide within the same square mile area was actually a good idea.

The big flyover for I-95's HOV lanes is fun to drive south on (one of Miami's two "postcard" vantage points... the other being northbound I-95 right after it splits off from US-1 and makes a hard left to the north, leaving the downtown skyscrapers laid out in front of you), but was a horrible waste of money. For what FDOT spent building it, they could have widened the mainline by TWO lanes in each direction AND built proper ramps from eastbound 826 to northbound 95, north and southbound 95 to westbound 826, and a few other directions.

I'm not 100% sure, but I think the I-75/I-595/Sawgrass Expressway interchange in western Broward County is the geographically largest interchange east of the Mississippi river. Not number of lanes, just total square meters of ramps and right-of-way. It's huge. From first split to last merge, it's more than a mile both east-to-west and north-to-south.

according to Texasfreeway.com the ramps going west on 635 at the high five are 1.4 miles and that is just one side

I thought that the Dallas hi 5 is the largest interchange in the world. But Pegasus will be much bigger than that just to the south of that. Ill try to find pictures.
