Title: Highest & Lowest AADT by State and Route Type
Post by: JayhawkCO on February 19, 2021, 03:41:13 PM
For each type of route (interstate, U.S. highway, and state highway), I have the highest and the lowest listed.  The data includes the route number, the actual AADT, and the mile marker where you can find that traffic level.  If it is at the end of the highway, I either put 0 or the total mileage (rounded).  If it's between two mile markers, I took the average of the two.  You can also follow the link attached to the mileage marker for a Google Street View of the location.

Title: Re: Highest & Lowest AADT by State and Route Type
Post by: SkyPesos on February 19, 2021, 04:03:18 PM
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.

They picked up the emergency vehicle on M-185 responding to stuff on Mackinac Island.

Similarly, I don't see any data at all for New Mexico U.S. highways. I put a request out to NMDOT, but haven't gotten the data back, so if someone can track down that info, that would be awesome as well.

I found a site for the "Mid-Region", but that's only one piece of the state.

For Indiana you list highest interstate as 80/90 at MM 6. At MM 6, 80 and 90 are separate roads and not together. My guess is that you mean 80/94.

Yep.  I found that too.  I found state highways; I found interstates; I found nothing for U.S..  Frustrating.

For Indiana you list highest interstate as 80/90 at MM 6. At MM 6, 80 and 90 are separate roads and not together. My guess is that you mean 80/94.

The entry is listed as "I 80/I 90, MM 6.0", so it must be the sixth mile of them being concurrent.  Is the Indiana Toll Road mileposted as one of either I-80 or I-90?  From the Wikipedia page, it doesn't look like it.

Similarly, I don't see any data at all for New Mexico U.S. highways. I put a request out to NMDOT, but haven't gotten the data back, so if someone can track down that info, that would be awesome as well.

I found a site for the "Mid-Region", but that's only one piece of the state.

Yep.  I found that too.  I found state highways; I found interstates; I found nothing for U.S..  Frustrating.

Then I'm sure you also found the maps with AADT ranges.

80 does not have its own mileposts. It uses 94 when concurrent with it and 90/Toll Road when concurrent with it. The 6th mile of them being concurrent would be at MM 27 of the toll road and there's no way that has the highest AADT. I'm pretty confident it's supposed to be 80/94.

MN contexts:

I-35W: this is the stretch near the downtown freeway stub merge/split and the I-94 junction in Minneapolis.
I-90: rural farmland east of Worthington.

US 212: the duplex with MN 5 just outside I-494 leading up to the Prairie Center Drive exit in Eden Prairie, one of the main commercial hubs of the southwest metro.
US 75: the dead-end section at Noyes

MN 100: the 394/100 interchange in Golden Valley, the main traffic shift point between the affluent southwest suburbs and downtown, also where the reversible express lanes on 394 end.
MN 89: Canadian border crossing west of Roseau, in the middle of nowhere, in an area well served with other border crossings.

As posted above, anything that is clinchable on Travel Mapping, so basically signed in the field with the exception of interstates.  I guess I should specify that I'm only using primary state highways.  Also, with your example above the AK7 listed as the lowest AADT is the one near Petersburg.

I'll give some context for the Utah extremes listed here:

I-15/80: this is within the Spaghetti Bowl interchange in Salt Lake City between SR 201 and I-80. That traffic is spread across a maze of ramps but there's no doubt this is the busiest place in the state road-wise.
I-70: halfway between Green River and Salina, way out in the middle of nowhere, between the two paved roads that go north to serve the only population in the area
US 89: freeway segment south of Ogden just south of I-84
US 6/50: west desert, basically an eastern continuation of Nevada's "Loneliest Road"
SR 201: major Salt Lake freeway, just outside of its interchange with I-215
SR 124: random spur to a now-abandoned mine, branching off another spur state highway well off the beaten path to anywhere

And I like the idea of the contexts for states.  This will also help to "validate" the data I pulled.  I already realized one of my numbers for CO was wrong as the Highway Explorer counted a frontage road as part of US24.

Colorado
I-25: Right between the main exit from downtown and the intersection with I-70
I-76: Between Ovid and Julesburg in extreme northeastern Colorado

US36: Boulder Freeway right after it exits from I-25
US160: Southeastern Colorado just east of the turnoff for CO389

CO470: Southwestern beltway of Denver between University and Quebec just west of I-25
CO78: The unpaved portion between Beulah and CO165
CO101: A random highway to nowhere (a non-town called Toonerville) in southeastern Colorado

Nope, that's a winner. Illinois is one of the states I couldn't download info for, so it was just zooming in and out on maps.  I'll update.

Also, I didn't realize that I-405 in California wasn't even the highest freeway in California, which is CA60 with 461,000 near the City of Industry.

More context for a state people rarely post about:

Wyoming
I-25: In Casper along the 20/26/87 concurrency.  This is probably one of the few cases of the highest AADT not being in the state's largest metro (or micro) area.
I-90: Northeastern Wyoming between I-25 and Gillette

US26/89/191: Between Jackson and WY22 which leads over Teton Pass to Victor, ID
US87: The northern stub of the landslide closed segment

WYO59: In Gillette just south of I-90
WYO28: In southwestern Wyoming about 20 miles NE of Farson on the way to Lander.

Context for Oklahoma:
I-44 MM 123 is in Northwest Oklahoma City, right at the interchange with other two highways that serve that part of town: SH-3 (Northwest Expressway) and SH-74 (Lake Hefner Parkway). Gateway to your upper-middle-class suburbia.
I-44 MM 31 is south of Lawton, just before the last free exit before the turnpike that carries I-44 to Wichita Falls. Useful, but not a direction most Oklahomans are traveling, clearly.

US-64 looks like it's somewhere in the Tulsa freeway system, possibly at the interchange between the Mingo Valley Expressway and the Broken Arrow Expressway. US-77 is kind of surprising, since it's in a fairly populated corridor its entire time in Oklahoma, but then again no, because I-35 does the same thing as US-77 and does it better.

The SH-3/74 concurrency is part of the aforementioned gateway to Northwest OKC; most of the traffic that passed through the segment of I-44 with the high count also passes through this section of 3/74. I was a little surprised to see SH-49 as the low, since I figured it would have been SH-87 or one of the spurs, but that segment of SH-49 is the back way into the Wichita Mountains Wildlife Refuge, so it makes sense there wouldn't be a ton of traffic there.

MM2 180 is just east of of I-82.

Technically speaking, US 30 should have top spot because of its overlap with I-84, but US 26 MM 73 is at the eastern Canyon Rd split just west of the tunnel.
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).

For South Carolina:

I-77- NC/SC state line going out of Charlotte, before Carowinds exit, a huge exit during the summer months with the amusement park, plus all the vacation traffic from OH/WV/PA/Canada heading south
I-185- little-used toll road that barely gets much use other than a cut-through to I-85 from 385, basically paralleling I-85 at this point, at SC 153.

US 17- Ravenel Bridge, pretty much the lifeline of the Charleston area, connecting Charleston to Mt. Pleasant and back.
US 301- north of Manning, between there and Florence, almost a ghost town, bypassed by I-95 40 years ago. Very few people live in that part of SC.

SC 277- Major road connecting downtown Columbia to I-77. This point is between I-20 and 77.
SC 901- At about the most non-descript terminus of two state highways (SC 200). No blinker even. Follows I-77 so all it gets is local traffic and not a lot of people live in that area at all.

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.

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.

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.

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.

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.

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.

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.

This is a fascinating table, thank you for pulling it together!

Looking at New Hampshire:

I-93 MM 20: In Manchester, the state's largest city, on the brief concurrency with NH 101, the main E-W highway across the southern part of the state
I-93 MM 118: Approaching the Vermont border north of the White Mountains, after splitting with US 3 but before picking up US 302

US 3 MM 43: Downtown Concord, literally in front of the State House. Though where US 3 follows the F. E. Everett Turnpike is much busier, at 124,820 between Exits 5 and 6 in Nashua as of 2015: PDF (search "FEET") (https://www.nh.gov/dot/org/operations/traffic/tvr/locations/documents/nashua.pdf). The US 4 portion of the Spaulding Turnpike is also busier than this at 67,673 in Newington as of 2015: PDF (https://www.nh.gov/dot/org/operations/traffic/tvr/locations/documents/newington.pdf)
US 3 MM 242: Canadian border crossing

NH 101: Just east of I-93 leaving Manchester, though there's actually a higher AADT of 58,000 between I-93 and Exit 1, rather than your 53,000 between Exits 1 and 2.
NC 16B: Loop off NH 16A in Jackson, serving a ski area and a lot of vacation homes

I assume you're not counting state highways without a posted route number? Because the portion of the Everett Turnpike that does not have a route number has an AADT of 91,000 between Exits 7 and 8 in Nashua, and it is a state highway that is clinchable in TM.



For Maine, I was surprised to see 295 higher than 95, but upon taking a look it seems the MaineDOT data does not include the Turnpike. It appears the Turnpike Authority does not publish detailed traffic data, at least that I can find, but I did find a consultant report from 2016 [PDF] (https://www.maineturnpike.com/MaineTurnpike2012/files/ca/ca96203c-3fb6-40a0-bf66-7f3ef7ef1521.pdf) that includes 2015 AADTs, and shows the highest as 74,006 between Exits 36 and 42 as of 2015.

Also note that MaineDOT splits volumes directionally on freeways. On I-95, if you add up the SB and NB 2019 volumes at the NH State Line you get 37,990+38,770=76,760 (down from 86,910 in 2017). Returning to I-295 in South Portland, north of Exit 3 you get 42,580+41,250=83,830. This would appear to be the most recent winner for Maine!

State route lowest: WI-55 between WI-32 and WI-70


An absolutely gorgeous, desolate drive.  Does not surprise me in the least that it has the distinction as the lowest.

This is a fascinating table, thank you for pulling it together!

You're welcome!

Looking at New Hampshire:

I-93 MM 20: In Manchester, the state's largest city, on the brief concurrency with NH 101, the main E-W highway across the southern part of the state
I-93 MM 118: Approaching the Vermont border north of the White Mountains, after splitting with US 3 but before picking up US 302

US 3 MM 43: Downtown Concord, literally in front of the State House. Though where US 3 follows the F. E. Everett Turnpike is much busier, at 124,820 between Exits 5 and 6 in Nashua as of 2015: PDF (search "FEET") (https://www.nh.gov/dot/org/operations/traffic/tvr/locations/documents/nashua.pdf). The US 4 portion of the Spaulding Turnpike is also busier than this at 67,673 in Newington as of 2015: PDF (https://www.nh.gov/dot/org/operations/traffic/tvr/locations/documents/newington.pdf)
US 3 MM 242: Canadian border crossing

NH 101: Just east of I-93 leaving Manchester, though there's actually a higher AADT of 58,000 between I-93 and Exit 1, rather than your 53,000 between Exits 1 and 2.
NC 16B: Loop off NH 16A in Jackson, serving a ski area and a lot of vacation homes

I assume you're not counting state highways without a posted route number? Because the portion of the Everett Turnpike that does not have a route number has an AADT of 91,000 between Exits 7 and 8 in Nashua, and it is a state highway that is clinchable in TM.

All adjusted.  Thanks for the good info.  I was unaware that the Everett Turnpike was considered a state route, so didn't bother opening that .pdf.

For Maine, I was surprised to see 295 higher than 95, but upon taking a look it seems the MaineDOT data does not include the Turnpike. It appears the Turnpike Authority does not publish detailed traffic data, at least that I can find, but I did find a consultant report from 2016 [PDF] (https://www.maineturnpike.com/MaineTurnpike2012/files/ca/ca96203c-3fb6-40a0-bf66-7f3ef7ef1521.pdf) that includes 2015 AADTs, and shows the highest as 74,006 between Exits 36 and 42 as of 2015.

I knew there were going to be some state intricacies that I wouldn't know, so again, thanks for the info.  I was surprised to have a number that low for the highest interstate, so that all makes a lot more sense.  That has been adjusted as well.

I have already said that the Arby's GSV was a mistake and I correctly posted the GSV that I wanted to post already.

I know, but I can go for a Smokehouse Brisket meal (sans mayo) right about now.
I don't mind Arby's. It's one of the fast food joints I frequent. I like local places though to be honest, I just had Tony's for breakfast this morning it's awesome.

PA's makes sense but with a question:

I-76 MP 342 is in Center City Philly between US 1 and I-676
I-86 is up in Erie County.

US 322/US 422 - is that a tie?
US 19 MP 28 puts that in SW PA, Greene County...that makes sense

PA 581 is in the Harrisburg area...I thought that maybe PA 309 or possibly PA 65 or PA 28 in Pittsburgh's North Shore might have been close.
And I'm sure there were several rural PA routes that were pretty low.

Yes, it was a tie.  I just forgot to format it.  It was the only U.S. highway combo that tied, and I only fixed it for state routes.  I'll get it updated. 

And re: other options, Pennsylvania was a "scan the map" state, so it's very possible I missed better candidates.  Please correct me if I'm wrong.

M-185 in Michigan shouldn't count.

D) In a couple of cases there were ties, so you'll see two rows.  I also included two rows for Michigan, as the state route winner is M-185 on Mackinac Island, but figured some of you would give me trouble for that, so I included the "mainland" winner.

Looks like I had a little clairvoyance.

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

And that short segment does have a count on the map:  over 2000 AADT every year since 2015.  Unfortunately, that's the segment no one here is interested in.

I did see that as well.  It's not like an AADT of 43 for TX349 is a traffic jam waiting to happen either. (https://www.google.com/maps/@30.1445513,-102.0741729,3a,75y,30.11h,85.13t/data=!3m6!1e1!3m4!1sw_ZBesn4_Uu-vlc5TaTgeg!2e0!7i13312!8i6656)  It's possible that would be lower than the cemetery.

I have clinched all of 34. Its very empty there. But it loses any through traffic left at 80 though most is lost at 74. It's about 12 miles shortcut over 74 and 80 or 110 but same amount of time. Though there is a secret bypass in Kewanee.
Also you can see traffic declines in 34 and 29 as you  approach 80 . Meaning little through traffic.
North of 6 it used to be 32 and merged with 6 to Omaha.
Also east of 39 there are some really empty stretches . It's really a dramatic change the Chicago 60 miles sign is meat Illinois 23 and it looks like middle of nowhere . A few miles down the road outside Sandwich it makes a dramatic switch tons suburban landscape and jumps to over 10000 .

For the PA routes, it's definitely PA 581 as you mentioned.  PA 28 is close but not quite.

But for US 322...I couldn't find the segment you found...MP 342 is in the eastern part of the state, and I can't find any standalone sections that high.  You might have the section concurrent with I-95?  I think US 422 is the standalone winner.

Great work! There seems to be an inconsistency between NY and NJ- NY's highest amount is 285,440 at I-95 mile 0, which is presumably the GWB, and thus should be the highest number for NJ. Yet NJ's highest listed amount is 194,158 on I-78 mile 52, the intersection with the GSP.

I'm also shocked that the lowest NY highway isn't NY 421, which apparently has an AADT of a mighty 124.

It probably is.  Traffic on NY 421 is measured just west of NY 30 and traffic likely drops a lot past Warren Point Road.  NY 344 was counted just west of the MA line - east of the parking lot for Taconic State Park.  I also wouldn't be surprised if these roads are highly seasonal (especially NY 421), and NY 421 was counted in August, and NY 344 in May.

Try removing https from the URLs. From what I understand with signatures, the character limit sees what you type in the text window, even if it gets formatted to go above the limit. You can also remove the closing [/url] tags safely, due to the way BBcode works. (This only brings you to 26.5K, but it's a start.)

I managed to get it postable, though without much room for comments. 24401 characters + 292 because the black boxes count as two each = 24693.

* Remove the closing [/td] before the [/tr] – but only those, or else it will break.
* Remove all tabs. They aren't showing as empty space, anyway.

You can save about 300 by replacing the state names with their 2-letter postal code and about 200 by writing e.g. 115K instead of 115123 for 6-digit numbers. If you can manage to replace the black boxes with anything in the Basic Multilingual Plane, that will save 292 (this forum uses UTF-16 to determine character count).

Adding the Streetview links is a nice touch. Looks like some of them aren't quite in the right location though.

For I-93 in NH you list the lowest volume at MM 118 but your streetview link is around MM 110. Here's MM 118: https://goo.gl/maps/z3vWe8iiqPWZjcNt9

For US 3 in NH the highest volume is on the Everett Turnpike, but your streetview link is to the Burque Hwy after US 3 exits the Turnpike. Here's the correct location: https://goo.gl/maps/78dfUGSean2AowBc6

You also mistakenly put the same URL for both highest and lowest on US 3 in NH.

Your links for the FEET and NH 16B are correct though!

I also looked into some of your MA data, and your highest volume location on US 3 is correct, however, it's just after the Lowell Connector splits off. Thus adding that volume to the Lowell Connector volume (25,973) yields an even higher total of 157,042 between MA 129 and the Lowell Connector. Unfortunately there's no counts from between those interchanges, but we can extrapolate.

Thank you.  I'll update this afternoon. 

Edit - Got a jumpstart.  All done.  I also adjusted the MM for MA-US3 since it looks like the AADT log was using old exit numbers instead of actual mileage or new exit numbers.  I defaulted to mileage.

Finally received the data from NMDOT so I could fill in the rest (and update the data with more recent (2017) stats).  All Google Street View links are added in the OP.

New Mexico
I-25 (Highest): Just north of I-40 interchange
I-25 (Lowest): In Socorro in between the northern exit for BL25 and before US60 merges

US70: Just east of I-25 in Las Cruces
US64: Just east of the end of US84 concurrency near Tierra Amarilla

NM423: The bridge across the Rio Grande in Albuquerque
NM1: Old US85 south of San Antonito

And this, then, makes NM the only state on your chart whose lowest SR AADT is on its SR-1.

It has an interesting history.  The road was NM1 (and much longer) but replaced by US85.  When they made US85 concurrent with I-25, they used the NM1 number again just for the segment between Truth or Conesquences and Socorro.  For a good chunk of that route, it's just a frontage road.  Also, when it branches off from I-25, it's not even signed from the interstate.  There are shields as soon as you get to the top of the ramp.

Having driven both stretches, I think the CA 60/I-215 multiplex is much more heavily traveled than CA 60 in Industry - and a contender for the world's busiest highway. Is there an AADT measured value for that part of Riverside?

Looks like new data is out for California. I'm going to ignore 2020 data, since that was obviously a weird year. But, according to 2019 data, the highest AADT in California is I-5 between 17th and Grand in Santa Ana, with an AADT of 504,000.

The highest AADT on I-215 anywhere is 253,000 between University and Pennsylvania in Riverside.

I'll update my chart for California at least tomorrow. If anyone else has states that they know have changed, let me know and I can update when I have time.

Edit: Here's the highest and lowest (still not reflected in the chart as that takes some work):

Interstates
Highest: I-5 in Santa Ana, 504,000
Lowest: I-5 north of Yreka, 7,500

US Highways
Highest: US101 in Los Angeles, 318,000
Lowest: US395 at Oregon Border, 760

State Highways
Highest: CA60 in Diamond Bar, 350,000
Lowest: CA299 at Nevada Border, 75

Yes Illinois is updated to 2021.
On the getting  around Illinois maps they did include 2020 to see how off it was. Though traffic is back here transit is not. It seems people will just drive and deal with traffic when its just 2 to 3 days a week in the office.
Thanks for this . It would be nice if there was a page to link to all the state traffic maps.

Link to the new traffic census data?  I’m interested to see where CA 62 east of Amboy Road to CA 177 is after driving it yesterday.

Interesting commonality between CA and WA: factoring the recent 2019 data in from JayhawkCO, I-5 is both highest and lowest for interstates, and US-101 is highest and US-395 is lowest for US routes.
