When I-25 was built across southern Colorado in 1959, what is now Exit 108 was basically a ranch road exit. A concrete culvert was used to allow traffic to pass under the freeway. By the 2000s, this had been connected to Purcell Blvd., a 2-lane road connecting the community of Pueblo West - which didn't exist when the highway was originally built -  to I-25. The original underpass is still there, and I have heard of no plans to upgrade it at this location. Most of the traffic is eastbound, but there is a race track on the other side of the freeway, and when that lets out it can be difficult for eastbound traffic to find a gap to enter. It's also scary coming off I-25 southbound, since you can't see a car coming out of the culvert until you're in the roadway.

IIRC, US 9W has one or two of these somewhere north of Kingston, NY that are signal-controled.

The one I'm most familiar with, in Fairfax County, VA, is on SR 611 near US 1 and the Occoquan River, though there are several others in the state of Virginia.

I believe it is in Saugerties.  It's where the old NY Central Westshore Line crosses over US 9W.  The signal is there because of a limited sight distance on both sides, if I remember it correctly as US 9W does an "S" curve at the crossing.
There are indeed two of them, on both ends of the one place where 9W is east of the tracks, following a very substandard route. It's as if NYSDOT intended to construct a new 9W on the west side to 55 MPH standards and never got around to it.

One I grew up with is Hobson Rd. in Wayne, NJ, also a candidate for lowest clearance.

There is a one-lane underpass under a railroad in Franklin, TN.  This is just outside the city limits on SR 252.  There is actually a blind 90-degree turn on both the southbound and northbound approach.  There is no way to know someone is coming until you get to the turn.  Yes I said that this is on a state highway with a county population of around 200,000 or so.

Great example!  Interesting how one side has an "UNDERPASS ONE LANE" sign while the other has a "ONE LANE TUNNEL" sign.

At one time there was a very inadequate railroad underpass near Cresson.  It was one lane and had a vertical clearance of about 10 feet.  That road was rebuilt elsewhere and has a normal grade crossing now.  The rail bridge is still there, but there's no road now.  http://goo.gl/maps/74C7j

Wow, I remember that one, from about the 1970's. Once we drove under it while a freight train was passing over - my mother was terrified. I, of course, thought it was very cool!

If we're talking state highways, NY 164 crosses under the Beacon Secondary line at a one lane underpass twice in rapid succession. Neither is signalized but traffic counts on the road do not warrant such.

Then there's this one under the Harlem mainline which is decidedly narrow but on a minor sideroad that's mostly not paved:


That was fun to drive through!
If you always take the same road, you will never see anything new.

Although striped for two lanes, the underpass itself is no more than 20 feet wide. I've seen enough 18-wheelers on 9W to know that this is effectively a single lane. Not even worth trying to get two cars under there, just because there's so little sight distance.

One I'm working on right now - look east from Bronx River Parkway Exit 9. The signal on the far side of the underpass is timed to coincide with the entrance onto the Parkway so there's never conflicting traffic.

There's one on the short duplex of CT 150/CT 71 near the Yalesville section of Wallingford, CT.  It's an Amtrak line, and a very low clearance for a state highway.

Va. 877 (Newington Road) has a one-lane underpass (under the CSX (ex-RF&P) tracks) in Newington, Fairfax County.

There's also one on Game Preserve Road not far outside the corporate limits of the City of Gaithersburg in Montgomery County, Md. under the CSX (ex-B&O) Metropolitan Subdivision.

Here's a tiny one off US 29 south of I-64.  Not a public road...

Here's a more modern 1-lane overpass, F182 over I-64 on Afton Mtn.

These are common all over the northeast of course, so here are just a couple that seem unique to me:

Actually that one's pretty standard, but I just like it. :-)

This one's very cool, because the one-lane footpath/private driveway shares an underpass with a creek.

Underpass of the Erie Canal (!). Looks like the Googlemobile couldn't fit under this one either, but you can step forward to read the plaque.

We've got a traffic-light-controlled one-lane underpass in Rockford, Illinois. While it's wider than one lane, the angle of the road and the Union Pacific railroad tracks was too acute (obtuse, if you're looking at it the other way LOL) for two cars to pass through at one time.  20th Street makes an 'S-curve under the UP tracks before crossing the Canadian National railroad tracks.

Here's approaching the underpass: http://goo.gl/maps/B0rPW

I think this might just take the cake for the lowest underpass on a public road. Sure as hell the lowest I've ever seen.

Maybe; here's what the inside looks like:

I do not know if this counts, but the tunnel under the front of the Philadephia Museum of Art, is one lane.  I do not know if you could consider it an underpass, but it is one lane.

I think the point of this thread is to list 1-lane underpasses that carry two directions of traffic, or are similarly sketchy. The tunnel at the Museum of Art seems (to me anyway) more like a freeway ramp - which there are plenty of.

I recently ran into a one-lane bridge over water when I was riding around in the Poconos with my friend Will a couple of months ago.  Unfortunately, it rained on our parade, so I didn't get any pictures.

And this early's 1900's one on Jim Cristal Rd (Old SH 24/39) in Denton County:
It predates the state highway, which was moved to the new alignment (now US 380) in 1930, which was around the time the number changed


That's a beautiful picture.
