I think it's interesting that here in California we never use the term interstate.
For a state the size of California, all the long distance interstates just end here (I-5, I-8, I-10, I-15, I-40, I-80) and are relatively short (with the exception of I-5). There's a lot of auxiliary routes (especially here in the Bay Area and the x80 series), but more often than not, the freeways here are state highways (like hwy 4, 24, 13, 85, and 87 in the Bay Area) maintained by CalTrans and our taxpayer dollars without federal money.
Its weird because people up here are weirded out whenever I put "the" next to the highway number. As if hearing "the 80" or "the 880" is weird.

I-95 (travels through Westchester Co., The Bronx, Upper-Manhattan, & New Jersey, it's almost always on the news and constantly at a stand still, it contributed to high astma rates in The Bronx as well.
I really think it's I-95 (New England Thruway, Cross Bronx, New Jersey Turnpike).
Some of the numbers you guys are throwing around are just off the charts. No way does a single interstate or highway carry half million cars a day or more.
Most of the busiest freeways in the country are in LA, some in Houston, Atlanta etc and as listed on the first page of this thread, they max out at about 400k in LA.
A very very busy 8-10 (4-5 each way) lane freeway will max out at about 225k cars a day. Some very wide freeways will get a little more like the 405 or 5 in CA, but after 4 lanes each way, each additional lane adds little additional capacity because of loss of efficiency (too much lane change etc). So a 10 lane freeway might get 250-275k max, but a 16 lane freeway will only get about add 75-100k to the capacity.
Anyway.
The busiest freeways in KS and MO are in the KC an StL areas.
435 on the south side of KC in MO and KS (8-10 lanes) gets about 150-200k a day.
270 in StLouis near 70 (10-12 lanes) is slightly higher at 160-220k a day.
I don't know. Phoenix Metro is a tossup between I10 and loop 101. I wanna say loop 101 because it's a nightmare 24/7 but I think 10 is busier, just better designed
I-70 in downtown Indianapolis has 175,000 a day. On the north side of Indianapolis the freeways are probably higher.
