So you come straight out of a tunnel onto this bridge? Looks cool.

A unique bridge with the floor beams mounted higher on the verticals causing the deck to be about in the middle.

I believe this was built in 1899, for the Washington Run Railroad, along with a tunnel and a railroad line to Star Junction, Pennsylvania.
