1-Lane Underpass

[7/8]

I got a few photos of a 1-lane underpass on Crewson's Line just north of Hwy 7 west of Acton, ON:

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.

This one is even more compounded by the fact that Clovercroft Road is "multiplexed" onto TN 252, if you will, through this area, which is an important east-west road linking Franklin to Nolensville.  Almost worthy of a state route designation itself.

TN 252/Wilson Pike pretty much parallels the CSX railroad for most of its length and, I believe, used to have a total of (4) of these one-lane underpass crossings, and is now down to two.  The one b/w TN 253/Concord Road and Crockett Road in Brentwood was replaced sometime in the mid-80's I'm guessing.  And the one further south near Ravenwood High School was replaced (and Wilson Pike realigned from west to east of the railroad) I'm thinking in the 00's, which replaced a wooden one-lane underpass as I recall.

The other one that remains is about a couple miles south of the one mentioned above, and can be found here:

Not a strictly-speaking-one-lane bridge, but this one is narrow enough to where I've seen cars stop to let vehicles through one at a time:

Another tight one:

I don't think this one has been posted yet, but there are two on US 9W near the Ulster/Greene county line.

Second: https://goo.gl/maps/Jf18ZTFVgEJ2

While the first one is technically 2 lanes, signals on either side only allow one direction under the bridge at a time. Second one is definitely one lane. And yes, these are on a US route in a state that typically keeps their stuff to pretty high standards.
