There's a small, unnamed ditch on the west end of town that empties into Hickory near the RV park.
Stream width based on streetview seems to fit the bill, although the house in the background no longer seems to exist.
Hopefully the tunnels don't catch on fire as easily as his cars :')
1) All 5 of the NBI entries refer to it as a tunnel (As does everyone from the federal, state, and local governments to news outlets to highway fanatics.), and as I already stated, stringer is the typical roof construction method for cut-and-cover tunnels, but I guess paying attention is hard.
2) This tunnel passes under a park built upon the backfill used to bury the it.
3) And now you're being willfully obtuse and willfully ignoring the actual engineering/design differences between cut-and-cover tunnels and overpasses.
Literalism and pedantry don't trump actual engineering.
Most recent NBI says it was replaced in 02.
I've found several references to this being a "cut-and-cover" tunnel project , which is how most tunnels are built nowadays, especially when being built in already-built-up metropolitan areas
Citing sites that refer to it as cut-and-cover:
Based on this aerial image from 1963, it was usable up until 1965.
Based on the 70s/80s GIS views, my I agree that the bridge was relocated here in the late 70s/early 80s
Additionally, the NBI gives "Winding Road" as the generic name for several roads in the Sierra National Forest.
A two-span bridge will have a gap between spans to allow for thermal expansion.
There's no gap, so it's more than likely a single span with additional support.
Looks more like a single-span Bailey-pattern truss with a support pier at the midpoint.
A half-through truss would sort of fit the bill: https://bridgehunter.com/ca/nevada/17C0024/
Reiterating a comment from below, that's a different bridge: http://bridgehunter.com/co/conejos/costilla/
According to http://phorum.dallashistory.org/read.php?2,92080,92088, a through truss, and based on https://books.google.com/books?id=zo5MAAAAYAAJ&pg=PA414&dq=M..., built 1923.
M.C., do you know the GPS coords for the actual bridge over Mountain Creek?
