How many numbered roads are there that only have 1 travel lane in each direction WITHOUT turning lanes for it's entire route? Seems like there shouldn't be that many, but I might be surprised how many there are. Preferably would like to find the longest route or a state route with only 2 lanes.
Example: FM 2185 in Van Horn, at 41.8 miles
https://www.google.com/maps/dir/31.0492629,-104.83149/31.4205144,-104.4539003/@31.2188837,-104.7352556,11.23z/data=!4m2!4m1!3e0
I'm sure there are others in Indiana, but IN 211 is the first one that comes to mind.
I'm going to say probably CA 127 in California at 97 miles. It looks like all turns at highway junctions are made from the two travel lanes in my photos:

Ontario Highway 599 in the remote northwestern part of the province is 292 km and does not appear to have any turn lanes.
M-185 :-D
Oh 288, Oh 203, Oh 656 to start with for Ohio.
There are many in WI but the longest one might be WI-131 at 79 miles. WI-80 is 176 miles long with only one four lane segment, which is in Platteville.
Without knowing any specific examples offhand, Northern New England, especially Vermont, seems like a good place to find some.
The only one I know of for sure right now is MO-103.
Since the supplementary system is lettered, I will leave those out..

The Arctic would also offer good choices, if you're not too fussy about calling unpaved highways with no lane markings "two-lane". The largely unpaved 416-mile AK 11 (Dalton Hwy.) would be a candidate.
Alaska's fully paved highways have higher traffic volumes, and usually have turn or passing lanes here and there.

I beg to differ on that one... (https://goo.gl/maps/TtJUGiToNYc7hDkt9)
Arizona's a tough one. Most routes run through a town or have something along their length that warrant multiple lanes, a passing lane or a turning lane.
Off the top of my head, State Route 97 is 11 miles and two lanes all the way. I'm open to other mentions if anyone knows any.
Was going to mention VA-40 at 219 miles ... if it weren't for a ~2 mile 4-lane segment near Rocky Mount.
VA-48 technically counts and is 323 miles long, but it's unsigned.

There are no paved roads that intersect with AZ 97, other than each end (US 93 and AZ 96). There's no turn lanes at either intersection.
I'm not sure if there are any on AZ 96, either.Edit: There are no turn lanes anywhere on AZ 96, from Bagdad to Hillside, where 96 becomes CR 62. However, CR 15 does have a left turn lane at its intersection with 96.
Minnesota's really good about turn lanes and bypass lanes, so this is going to take time to figure out.

96 has a climbing lane about 15 miles east of Bagdad where it snakes up some S-curves, so it's out.
I've visited Bagdad a few times. I was certainly impressed by the quality of county roads between Bagdad and Prescott, and the relative lack of state highways serving the area.

Actually, Skyline Drive and the Blue Ridge Parkway have extra turn lanes for short distances at many of the "interchanges". In fact, there is a short section of 4-lane Skyline Drive over the bridge crossing Lee Highway (US-211) just outside of Sperryville. Most of the "two-lane roads" that I last traveled now have these occasional or infrequent turn lanes.
I'm sure a bunch of the short rural roads in Illinois count, such as IL-147, IL-184, IL-152, IL-109, and IL-119. I wonder if a few longer roads like IL-108 also make the cut.
Off the top of my head in Vermont: 5A, 65, 102, 122, 215, 232.

VA 40 also has a very brief 4-lane segment near Stony Creek. The Virginia Highways Project mentions which of VA's primary highways is the longest with no multi lane segments, but I can't remember which one it is.
I would assume lots of the Kentucky state routes that don't connect to an arterial route would fail to have a turn lane.

This needs updating. FM 2185 was extended in 1968 SH 54 to FM 652, a little over 80 miles. About 41 miles was built on the south end, and 6 miles was built at the north end, but the middle part was never built. It's a series of unpaved county roads. For a long time, FM 2185 had a about a 30 mile gap in it. In 2006, the north end was redesignated as FM 3541. Last month, in August, the old designation was restored. FM 3541 is now FM 2185, and the unbuilt middle 30 miles is again designated. The former FM 3541 has a split intersection with FM 652, where the road has 4 lanes (two turning to or from the west, and two turning to or from the east). FM 2185 qualified until a month ago.

Here are some FM/RMs that qualify:
2886
1989
1312
864
2023
3078
1832
2119
2810
919
1437
1576
2249
Here are some more FM/RMs, but these are just a few miles long (or less):
2093
1706
3166
1859
3450
The easternmost I found is 3049. It runs 4 miles from FM 67 to FM 934, near Whitney Lake, almost as far east as I-35.
I found three non-FM Texas examples. One is Spur 77, if you consider the road as TxDOT has it mapped, which does not include the parking lot. Another is Loop 293, which has an intersection with FM 11 in the middle, but has no intersections at its ends. It simply converts to and from I-10 frontage roads. The other is Park Road 5, which runs through Palo Duro Canyon State Park. There are some other park roads that never have more than two lanes on a single roadway, but have a set of loops and spurs and are not continuous.
I really wanted a state highway example. The closest I got were 128 and 254, but they have at least one turning lane at the intersection on the east end of each.
I just remembered the special highway. TX 165, which runs to and through the Texas State Cemetery in Austin. It runs along Comal St. from Seventh St. to the entrance to the cemetery, and along the cemetery drives. The part in the cemetery has barely one lane, and has nightly closing hours. The Comal St. section has only one motor vehicle travel lane in each direction. It's very short, and is a special-use roadway, but it is a designated state highway.
I think I actually found a few in New England
MA 43
MA 78
MA 142 (VT 142 almost - it's northern end has a right turn lane to VT 119)
MA 148
NH 78
Probably others. They are the only ones I thought of looking at Google Maps and confirmed with it.
Amazingly, WV-501 (eastern end of Tyler Mountain Road) from North Charleston to Tyler Mountain is still two lanes for its entire route.
Tyler Mountain Road breaks off to the north of WV-62 (old US-35 from before the Silver Bridge disaster) then crosses back over to the south of WV-62 at aptly named Cross Lanes. However, the section west of Tyler Mountain is part of WV-622, which is routed up the Lanham Route (Rocky Fork and Martins Branch) to meet LSR-21 (old US-21) at Pocatalico. The Lanham Route is also two lanes all the way, but the suburban section of WV-622 has been upgraded to 3 lanes and 4 lanes through Cross Lanes back to I-64.

Many fmr routes are like WI-84 WI-99 WI-109 WI-123 WI-184. As far as current routes WI-68 WI-75 WI-101 WI-102 WI-105 WI-106 WI-111 WI-112 WI-118 WI-127 WI-134 WI-137 WI-155
NJ59, NJ163, Maybe NJ413 if you don't count the toll booths along it and the turn lanes onto US130.
NJ 140 just misses the qualifications due to a 300 foot section of 4 lane roadway. This is all the more incredible because the road has intersections with 2 US routes and interchanges with 2 highways, yet all but 1 of those ramps don't have accel/decel lanes nor turning lanes.
The closest to me is PA 341, but it's only 10 miles long. PA 17 also qualifies at 35 miles long. I'm sure Pennsylvania has more examples, but these are the two I've found so far.

Similarly, WV-66 in and out of Cass remains two lanes.
There are not a lot of New York examples. NY 262 (17 miles in length) is the only one I can find, but it qualifies in style, complete with a multiplex (https://www.google.com/maps/@43.066503,-78.1892261,3a,25.3y,37.26h,89.28t/data=!3m6!1e1!3m4!1sq6KQSzTzaaMYkPNPwjj9jA!2e0!7i13312!8i6656!5m1!1e1)!
Any other examples that qualify even with a multiplex?
Another candidate: ~ 100 mile-long Nevada 375 (Extraterrestrial Highway), passing near Area 51. No turn lanes at either end, or its one community/tourist trap Rachel, or the Alien Research Center near the south end.
Oklahoma may have a higher number of these than other states, since they have a tendency to use slip ramps for right-turning traffic, rather than turn lanes, at major highway junctions. We also have a lot of short connector highways. Just sticking to McClain County, OK since I know those: SH-74B, SH-130, SH-24, SH-133.
If any examples exist in Pennsylvania, I assume they'll be relatively short, low volume state routes in rural areas that do not serve a significant purpose as through routes.
On a hunch, I checked out a route that I mentioned in the Signed state routes that dead-end (https://www.aaroads.com/forum/index.php?topic=27292.msg2519142#msg2519142) thread: PA 660, which primarily serves to connect US 6 to Leonard Harrison State Park. It appears to qualify. Through PA 660 is signed along Wellsboro's Main Street, it avoids having any turn lanes, at least in part due to the width of the street and its function as a pedestrian-oriented shopping street. PA 660 very narrowly avoids having a turn lane, too, as the section of Main Street immediately north/east of Queen Street (https://goo.gl/maps/KqcBHavvFWs2Ny6y9) (which is part of US 6) has multiple turn lanes–befitting the more auto-oriented business in that stretch (supermarket, motels, gas station). Traffic volumes are low enough that where PA 660 makes a 90-degree left turn (https://goo.gl/maps/EczUbekZWj58B4FKA) west of town diverging from PA 362, no turn lane is provided.
Quote from: webny99 on September 23, 2020, 12:05:04 PMAny other examples that qualify even with a multiplex?
From the example above, PA 660 is co-signed with PA 287 in Wellsboro.
Another that appears for work is PA 554 (https://goo.gl/maps/rrE3vTvqVZGmm41c9), a winding mountain road that connects US 15 in South Williamsport to the sparsely populated valley south of Bald Eagle Mountain. Traffic volumes are low: AADT is about 1,100 near South Williamsport and only 600 at the southern end (before it makes a 90-degree turn onto Elimsport Road to make the connection to PA 44).

That must be outdated imagery. MoDOT installed a bunch of them along MO-13 between Springfield and Clinton a year to a year and a half ago. I use the J-Turn at MO-123 every month or so.
This is harder than I ever imagined. Given the coal truck traffic, even some tiny roads in West Virginia like WV-97 have been upgraded with truck lanes in a few places.

Well then the base map (https://www.google.com/maps/@37.764038,-93.5592403,17.59z/) doesn't have it right either.
Technicality: the various sections of WV-102 are only two lanes, but Virginia's sections of VA-102 include several sets of truck lanes and the southern terminus of College Avenue at US-460 in Bluefield (Virginia) is multilane divided. Even WV-161 along the Virginia line west of here has several sections of truck lanes.

MA 142 (VT 142 almost - it's northern end has a right turn lane to VT 119)
At one time, there was a marked left turn lane on MA 142 SB at Bennett Brook Road. It now appears to be unmarked, though the SB lane remains extraordinarily wide approaching the intersection. More Massachusetts weirdness.
Add to the list:
VT 25A
VT 25B
VT 26
VT 35 (maybe? Two two-lane legs at VT 30)
VT 44A
VT 121
VT 123 (again maybe, with two two-lane legs at US 5)
VT 244
Forgot Arizona SR 366, and it's right in my back yard. (d'oh!)
34 miles, not a single turn lane or passing lane along its entire length. Thankfully it does have the occasional wide spot in case your passengers are prone to carsickness.
Arizona 78 and its NM counterpart, NM 78, similarly cover a length of about 34 miles between US 191 and US 180.
The only part wider than two lanes is at the western terminus, where it has a turn lane to match the other three legs of the intersection.
