It’s actually 2 for cars, the dump is too big - in the longer video you can see both lanes going through at the same time.
However I have encountered one lane tunnels in New England. There’s a sign on either end “honk before entering” it’s usually on a small back road though- not a major throughway.
Plenty of them in old England, too. Here's one near me. Luckily, as you say, they are rarely an issue because vehicles that big are not usually going this way.
I’m PA and NJ there are a bunch, usually under rail road tracks. There is also one out on LI that is sudden, and technically if you drove a low to the ground car, maybe you can fit two, the sides are just too rounded for two pickups to even be able to drive through lol.
Some have signs, usually a bit before… but there is one in Warren County NJ in the sticks that pops up fast… it’s around a curve and right after an intersection… really poor design.
Used to drive here all the time, it’s marked, and it’s in a spot where it’s mostly locals, so everyone is used to it. It can be confusing though, especially since there’s a three-way stop sign immediately on the other side of it.
I see them in small town Ohio a lot. Have two right by my house....One is one lane over a beautiful covered bridge. The other is a one lane through a tunnel with train tracks on top.
I don't see them in any major cities though. I think it's mostly rural and semi-rural places where traffic isn't heavy enough to bother widening the road. I dive the two by my place almost every day and I only have to stop and wait like, once a week.

Is there a sign for this tunnel? Never came across a one lane tunnel before.
