Lightest traveled 4 lane road in your state.

[jeffandnicole]

If I had to guess...and this is probably a really bad guess...there's a section of US 130 in NJ below the Commodore Barry Bridge (and more specifically, below High Hill Rd) that's 4 lanes with very little traffic.

Looking up NJ's classification/volume counts, this section of roadway has an ADT of around 6,000 vehicles weekdays ( https://www.njtms.org/map/tms_reports/reports/DV03S_7-4-246_8-16-2018.pdf ; they list the road as E/W rather than N/S).  While fairly high compared to a few of the others mentioned, it's very low for a NJ 4 lane roadway.  Go 3 miles to the north on the section of 130 between 295 & 322, and daily volumes jump up to around 27,000 vehicles!

It looks like the winner for Maryland is US 113 on the Eastern Shore near Snow Hill - lowest AADT I found was 6,162 just south of the MD 12 intersection.

(Although I wonder if US 301 just before the DE border could take over depending on how much shunpiking occurs - last time I drove up that way, most of the cars I could see in front of & behind me turned off at Sassafras Road.  Most recent AADT is 11,462 south of Sassafras Road, and 11,393 north of it.)

DelDOT's traffic count simply shows 21,244 AADT for the entire toll road.

When I drove it this summer, it appeared to have the same amount of traffic roughly as was on US-301 in Maryland.

AL 62 near Guntersville AL. It leads to and abandoned industrial facility. This ain't my state, but I feel its worth noting here https://www.google.com/maps/@34.4330391,-86.2036825,5683m/data=!3m1!1e3

Yup, that was my guess for Alabama. ALDOT shows a steady 150 per day, though that's bumped to 190 as of 2018. There's a few homes near the end of the route.

Daily counts under 800 for anything on the state system are uncommon for 2-lane sections, but AL 62 takes the boondoggle cake. I'm trying to find much of anything else carrying under 2000/day which has four lanes, although the ALDOT map also includes some random locations that are not on the state system.

I’m sure its some part of the IL 110 CKC in Western IL/Forgottonia, but no numbers data

Numbers data for IDOT?
http://www.gettingaroundillinois.com/gai.htm?mt=aadt

IL-336/IL-110 sees at least an AADT of 3,000.  That's still more than I-180, which sees less than 2,000 across the Illinois River Bridge, and no more than 4,000 on the north-south section.

[jemacedo9]

PA 61 just west of Centralia shows an AADT of 1,500...

[3467]

Brandon's right. There are only a few expressway projects alive downstate. Small sections of IL 127 and US 34 and US 67 . There are a couple of sections of 67 that come close. 180 is a wild story maybe warrants a thread in Midwest sometime.

For some reason my iPad doesn't like that site

Haven't played around with it on my MacBook in awhile. It does work better on the MacBook, tho

Thats pretty incredible, that 110/336 gets more traffic thru Forgottonia than I-180 gets, tbh. Then again, 180 is the Interstate to nowhere. IDOT should go ahead and use "Nowhere"  as the 180 South Control

[webny99]

180 is a wild story maybe warrants a thread in Midwest sometime.

Not sure if it's ever had it's own thread, but it's been discussed ad nauseam in other threads, especially threads about least-important, least-used, and otherwise useless interstates.

I can't even zoom in on the IDOT AADT map for US 51 between I-57 and the River Bridges in Cairo. It is 4 Lane in town, but I can't imagine it sees much traffic

I don't head down to Cairo that often, but the times I have, it is pretty much a ghost town

[3467]

Actually Cairo is 3700 to 5000. 180 still Champ.

[3467]

I think there is some sort of perception issue 5000 can look busy on a 2 lane especially the older substandard ones Illinois has but make it Any kind of 4 lane expressway undivided urban or rural it looks pretty empty.

Must be more truck traffic using the Ohio River Bridge than I would have thought. Interesting. Most truck traffic going across the Mississippi will stay on I-57

Next I'd check Packers Ave in E St Louis

[gonealookin]

US 50 gains third and fourth lanes for about a half mile through the town of Eureka, Nevada.  AADT in the center of town is 1100.

I also found an 1100 on NV 223, which serves as Business Route I-80 through Wells, NV, part of it being old US 40.  Despite being alongside I-80 there's very little business on that Business Route, particularly after a 2008 earthquake which severely damaged a number of the buildings in town.

After ten days in Cairo, I can confirm there's a heckuva lot of truck traffic passing through, but not much local traffic.

Ridge Route Alternate AKA Golden State Highway (former US 99) comes to mind in California.

Were you thinking roads like Ralphs Ranch Road, part of the 1933-era Ridge Route through the Grapevine?

I think this could actually be the winner. There seems to very few businesses along this particular stretch of the Old Ridge Route.

A decent percentage of the daily traffic on the US 51 bridge is trucks. A news release went out today about a work zone that's going to include a significant width restriction. Those releases usually include the percentage of truck traffic, but this one didn't. However, the traffic count map indicates it's around 35 percent truck traffic of an ADT of a little less than 5,000.

Looking at rural 4-lane arterial highways vs. urban examples, US-58 in Virginia near Meadows of Dan carries 1,400 AADT.

I found another 4-lane divided highway with a lower count in Virginia.

When I-95 was constructed through central Virginia, it took over most of pre-existing 4-lane US-301, reducing it to a 2-lane frontage road. In a couple areas however, I-95 diverged onto new alignment and the old 4-lane road was left in place. South of Carson, VA, where I-95 diverges to bypass the town and US-301 expands to its original 4-lane section, it carries only 780 AADT.

The lowest I could find in Louisiana is US 165 near Georgetown: 1816

Nice find, did not think of that.

Aha! The Virginia example above suddenly reminded me of another one for NY. Why I didn't think of it sooner, I don't know.

There's no street view, unfortunately, but the southern end of South Pkwy on Grand Island is four lanes divided and has an AADT of 808. That's quite possibly the only four lane road with an AADT under 1000 in the entire state (excluding examples that are inside state parks, like Hamlin and Fort Niagara).

[DandyDan]

The lowest I could find in Iowa is 3040 (in 2017) for US 63 on the New Hampton bypass north of US 18/IA 24.

The western end of the LOSP shows an AADT of 551 in Traffic Data Viewer.

Doh!  And to think that I was the one that originally mentioned that segment in the other thread.

For some reason, I was thinking only of non-freeways in the context of this thread, and completely whiffed when composing that post. It would be weird, though, if the freeway answer for NY ends up being lower than the non-freeway example, which is how it's looking right now.

Probably Whitney T. Ferguson, III. Road in Vernon.  That whole interchange is overbuilt TBH, but heaven forbid they widen Bolton Rd.
