Easily the Surekill Expressway section of I-76 in Philly. I was just on this road yesterday at the height of rush hour on my way from Philly to Allentown. I’m sure there are others.
Decommission 128 south of Peabody!

Lowest untraveled number: 56

What is currently the section of I-41 between Appleton and De Pere, WI with the highest AADT?  It is programed by WisDOT for upgrading from 4 lanes to 6 lanes in the mid to late 2020s.

I-41 AADT: 76,200 between STH 47 and CTH E. (2019)

Wisconsin traffic counts can be pulled from this map. It does contain a variety of traffic count types which means the data doesn't always mesh well. More data can be found at the links found here. Hope this helps.

76,200 - Short Duration - I-41 BTWN STH 47 & CTH E - HPMS
54,100 - Continuous - I-41 EAST OF CTH E - APPLETON
51,200 - Continuous - I-41 BTWN STH 441 & CTH N LITTLE CHUTE
58,400 - Short Duration Class - I-41 BTWN CTH N & STH 55 - HPMS
54,200 - Short Duration - I-41 BTWN STH 55 & CTH J
53,400 - Short Duration - I-41 BTWN CTH J AND CTH U HPMS
44,500 - Continuous - I-41 BTWN CTH U AND CTH S DE PERE
46,700 - Continuous - I-41 BTWN CTH F & CTH S INTERCHANGES HPMS
59,100 - Continuous - I-41 BTWN CTH F & CTH G DE PERE #2 (it looks like a lot of traffic is added north of Scheuring Rd.)

The reports of 140k ADT on a 4 lane highway are stretching the limits of capacity. Under ideal conditions, a single lane can support about 2,000 vehicles per hour, traveling at around 30 mph by experienced drivers traveling in a fairly well organized platoon. As soon as something out of the ordinary happens, a jam condition occurs upstream and the whole thing breaks down, and you are on the other side of the "capacity curve". Theoretically, the maximum 24 hour capacity of a 4 lane is in the neighborhood of 192,000 a day, which would be the perfect platoon 24/7, and obviously not happening anywhere in the real world. A 4-lane roadway with 140k has to be near or in jam conditions for probably 12+ hours a day.

That sure sounds like the Schuylkill to me. Luckily I have never had the misfortune of driving on the road, but I have often been a witness to heavy congestion on the six lane section between University and Girard from the nearby rail line at varying times and days of the week.

Ted Williams Tunnel in Boston.

Ted Williams Tunnel in Boston.
I went through it shortly after it opened, before it was connected to the Pike.  It was a breeze...especially compared to the mess that were the Callahan and Sumner Tunnels.

What's the busiest non-freeway four-lane?

OK-9 in Norman (an expressway with stoplights at each intersection) is at 34,300 with no plans to upgrade.

^^ Or a 4-lane city street:  29,500 (2018) on Claude Allouez Bridge in De Pere, WI. East approach is a 2-lane roundabout.  It replaced a 2-lane bridge in 2007.

The short stretch of NY 31 between I-590 and NY 65 is at 42k (data from 2019). Fortunately it's only a short stretch, but south/eastbound still backs up constantly. And it's still pretty busy beyond there, with 33,110 between NY 65 and French Rd.

The section with 42k AADT actually used to have a third lane south/eastbound, but the lane was removed because it became a right-turn only lane and traffic in that lane would be moving at speed while the other two lanes were backed up for the light at NY 65, creating a dangerous situation for anyone trying to enter/exit from any of the businesses along that segment (cars would think it was clear or that drivers were waving them through, only to realize too late that the third lane was still moving). 

That's definitely the highest in this area, as NY 104 in Greece was 6-laned about 10-15 years ago (AADT's roughly 30k-40k on the 6-laned segment). The closest now would be NY 441 where it transitions from expressway to surface street entering Penfield. That's at 32k, and thanks to the overburdened intersection at Five Mile Line, it often backs up a mile plus during the afternoon rush

MA 2 through Concord: 48,922.
Clinched, minus I-93 (I'm missing a few miles and my file is incorrect)

Traveled, plus US 13, 44, and 50, and several state routes

I will be in Burlington VT for the eclipse.

The BQE triple-cantilever section was at 144k before the lane reduction (and before COVID). Still, it's gotta be near the top if not at the top.

I don't know how busy the new four-lane Midtown Tunnel AADT is. But the old two-lane tunnel was the busiest two-lane road in Virginia at 46,000 AADT. I commuted through it twice daily and it was normal to wait 20-30 minutes on Hampton during the evening rush hour to enter the tunnel. It seriously needed that new second tube.

Really? Former first place is 37K, former second place is 34K, and former third place is 30K. This is across the entire country.

The Midtown Tunnel's second tube opened in 2016, before that thread started.

That's just what people reported on that specific thread that were paying attention to that thread. Nothing official about that list.

Bumping this to ask: I wonder what happens to traffic when you take one of the busiest four-lane surface streets and add a new Whole Foods Markets (the first ever in the Rochester area)?

I don't know yet, but we're about to find out: https://www.rochesterfirst.com/news/business/brighton-whole-foods-planned-to-open-by-february-2023/

I'd hate to see the hourly numbers on this road after a Packer game.

:wow:
