Highest & Lowest AADT by State and Route Type

[tdindy88]

Indiana

Interstates:
I-80/94 - The Borman Expressway between Cline Avenue and Burr Street in Northwest Indiana. Not a surprise at all being THE major non-toll freeway on the south side of Lake Michigan

I-69 - Between SR 58 and US 231 in northern Daviess County. This stretch is very quiet compared to all the other interstates in the state. But surprisingly INDOT's traffic count map has this stretch at 6,161, so it may have even less traffic than on the database

U.S. Highways:
U.S. 31 - This appears to be US 31 between I-465 and 106th Street in Carmel on Indy's north side. It is a busy stretch of roadway with several ramps connecting 465 with US 31 and 106th Street.

U.S. 136 - The lowest count here is along US 136 southeast of Crawfordsville, presumably around New Ross. With I-74 paralleling to the north there isn't much of a reason for traffic along this route.

State Highways:
SR 62 - The Lloyd Expressway in Evansville just east of Downtown and west of the interchange with US 41. Not a surprise given this is a six-lane freeway-like highway.

SR 158 - A very quiet stretch of state highway in western Lawrence County between one of the gates to the Crane Naval Warfare Center (not their main gate, likely for just a few vehicles) and Bedford.

I ended up on that highway when I clinched Lawrence County. I wondered where the hell I was at lmao.

Maryland, Missouri and Ohio with I-270 in the highest... That’s 3/4 the I-270 variants! Interesting seeing it 3 times on the list, as someone that lived in StL and Cbus in the past, and visited DC a couple of times.

For the mile markers, 14 for STL’s 270 makes sense, as a lot of drivers use that part of I-270 to change from I-64 (exit 12) to MO 364 (exit 16) or I-70 (exit 20).

33 for Columbus’s I-270 is different from my guess, which is 23 (the stretch between OH 315 and I-71), but I guess New Albany developed to a point that part of I-270 to change from OH 161 to I-670 is much more used, also the Easton Mall’s exit is 33. A project that added C/D lanes between I-670 and Easton also finished last year in that area.

Additional context for Ohio:

For most of 2019, 14 was the last exit on I-680. At mile marker 16, the only traffic remaining on I-680 are the ones coming from WB I-76 and going to EB I-76, so it was pretty much a glorified ramp at that point. A new exit 16 opened to OH 164 right before the merge with I-76, so that may change the AADT data a bit.

Mile marker 108 of US 33 is where its western interchange with I-270 is. A lot of residents in Dublin use that portion of US 33 to/from I-270 to one of the two Dublin exits on US 33, Avery-Muirfield Dr (107) and Post Rd (106). The Dublin traffic makes up about half of those on US 33 at that point, as the AADT drops to 40k west of exit 106.

US 52 at mile marker 127 is across the river from Quincy, KY (with no river crossing ofc), and the area within 5 miles from that point in both directions is pretty isolated, with very few outside road access. An intersection with OH 125 is 4 miles east of that point, at mile 131. OH 125 acts as a shortcut for US 52 between I-275 and that point, as it's a straighter route, compared to US 52 paralleling the Ohio River.

The freeway section of OH 315 is naturally busy, connecting downtown and Ohio State to northern suburbs like Powell and Dublin. It's in the backyard of Ohio State, which contributes to a good amount of traffic on OH 315. What I don't get is mile marker 4. It's between the Medical Center (3) and Lane Ave (4) exits, the two exits serving Ohio State. Guess it's the combination of people entering on the previous ramp and exiting off the following ramp?

OH 371 is one of the shortest state routes in the state, and it's pretty much a driveway to a rangers station for a nearby state park.

Doesn't Texas SH 165 run through a cemetery in downtown Austin? That one has to be really low.

And you're right again.  Highest is at 262.  And I somehow got the number way wrong for the AADT.  Adjusted.

Madison's Beltline is interesting because there's not a lot of thru traffic, and barely anyone drives it from beginning to end at any given time. I've probably been on it 500 times, and I've never driven more than two thirds of it at one time. And it's not that long either. Also, there are a handful of major exits where the vast majority of the travelers get on or off it (US-18/US-151/Verona Road, US-14/US-151/Park St, John Nolen, US-51/Stoughton Road, I-39/I-90). The rest of the exits just take up space in comparison. All of that leads to large changes in AADT over short distances.

[Bickendan]

I'm unclear about US 395 MM 64, as that can be on one of three distinct segments (Pendleton-John Day, John Day-Burns, Burns-California).

It's the Lakeview/Burns segment.  It shows an AADT of 220 from MM 37.28 to 90.02 as measured from Riley and US20 (because Oregon does things weirdly).  So, I think technically I should have it at MM70 as measured from the California border if I'm taking the average. (134 miles from Riley to California minus the average of 37.28 and 90.02)

Chris

Burns-Lakeview makes sense. MM 0 is at US 20, however, not at the CA/OR border.

[hbelkins]

I'm just going to say that KY 1679 is a fascinating road. Basically a double-track dirt path in some places that somehow got a state-highway designation.

KY 1679 is the Little Shepherd Trail. It runs along the crest of Pine Mountain between US 421 in Harlan County and US 119 in Letcher County. I drove it with my dad a long time ago; sometime in the 1990s. At the time, it was paved between US 421 and the next highway crossing (a four-digit state route that links KY 221 and US 119), gravel to KY 160, paved through Kingdom Come State Park, and then gravel on to US 119. Since that time, the rest of the route between Kingdom Come and US 119 has been paved. The route is around 40 miles long and it took us four hours to drive.

I'm really surprised that Kentucky's lowest ADT isn't either the gravel portion of KY 199 in Pike County (known locally as Dinky Road, and it serves no houses) or KY 666 along the Ohio River bottoms in the western part of the state. Kentucky's photolog viewer doesn't even cover that portion of KY 199.

Doesn't Texas SH 165 run through a cemetery in downtown Austin? That one has to be really low.

I hear that section of road is dead.

That's how it's marked?  I just assumed it was internally marked one way but actual mile markers were like other states.

Yes, because that's ORH 49, running from US 20 to OR 31.
OR 31 and US 395 from there to California is ORH 19.

Btw since I posted it here I'll have to say that this is one of the most ghetto Arby's I've ever seen in my life. They even have a door in the bathroom that goes into the kitchen, who knows if that door is locked or unlocked from the kitchen side.

What road is second-lowest? If that road has an AADT of more than several hundred, I think we can safely say TX 165 is the winner even without data.

[Flint1979]

TX-165 also covers an unsigned portion outside of the cemetery so that stretch probably sees some traffic.
