Post it, please.
I have a picture of this bridge if you are interested.
I think that I have found this bridge and added the map location. This is the only place that shows State Route 660 passing underneath a railroad in the area, and the bridge type and dimensions match those shown in the information.
I have yet to find the bridge. I used to go to Collage in C-burg, although it was 20 years ago. The placement on the map shows nothing even close. However -- the Montgomery Tunnel is not far away from this location.
