Busiest 2-Lane Roads

[steviep24]

In my area, NY 286 is painfully busy, with an AADT of around 20,000 and a nasty lane merge to kick off the two-lane segment.
NY 404 (Ridge Road) has a slightly lower AADT, but the high volume and frequency of stoplights makes the congestion equally bad, if not worse.

The 2 lane section of NY 441 is nasty as well and may be the busiest in Monroe and western Wayne County. The 2 lane sections of NY 104 (especially in Wayne County) is very busy and due to Thruway shunpiking NY96 and US20/NY5.

In Delaware County, PA, the two-lane section of US 322 between US 1 and I-95 maxes out at 27000.

According to the 2016 map, that section is down to 24000.
PA 23 in Phoenixville (around the corner from me) is at 25000
US 222 east of Kutztown is 27000

US 222 east of Kutztown is 27000

I think this is the winner for PA. Even US 30 from Lancaster to Coatesville barely exceeds 20,000 on the two-lane portions. Interestingly though, PA 501 north of US 30 gets 24,000. I think it's about time they consider a Lititz Bypass for 501 connecting over to 222. :P

[US 89]

After a quick look through the UDOT AADT numbers, it appears that the Utah winner is 1300 East in Salt Lake City between 1700 and 2100 South with an AADT of 30,000. I've never seen that road not congested. Thing is, it has exactly zero chance of getting widened. It used to be State Route 181, but it was given back to Salt Lake City in 2007. The city then did a road diet on everything between 500 S and 2100 S, just so they could put in bike lanes.

NY 31 has several segments (both west near Brockport and east near Macedon) that are busier. You can find AADT for anywhere in New York here. I wish other states did interactive maps like this one. *cough* PA

That is a really neat tool!  Any state besides NY do this?

Also, WA (WSDOT traffic data geoportal): http://www.wsdot.wa.gov/data/tools/geoportal/?config=traffic

WSDOT recently updated their numbers, putting the section of 522 north of Paradise Lake Road at 29k AADT (up about a thousand from last year).

^ I'm having trouble with that link. I can see "layers", "legend" and "tools" pages, but not the map itself. Maybe just a mobile device thing.

What I like about maps like these is that the roads with the highest AADT are easy to spot, and from there it's relatively straightforward to identify the busiest two lane roads (and four lane, and so forth).

I'd like to see what every state has to offer in the way of an AADT map. I'm intersted enough that I'll be forgiving of maps less user-friendly than the NY map

Works on my Galaxy S8+, but the map is extraordinarily small...
