Description 

from the 2002 survey: "The skewed 3-panel Pratt half hip pony truss bridge is pin-connected with cast iron connectors. The west abutment is stone encased in concrete. The east abutment and wingwalls were rebuilt in concrete in 1955. The bottom chord is stamped eye bars with shop numbers. Many welded alterations, including plates on the top chord and the cast connections, additional diagonals, and outriggers."

2012 note2: east abutment also has a 5 foot diameter bypass tunnel in it. Skew angle is minor. Truss parts are numbered with marker pen; should we be concerned? Bridge parts appear to be in good, low rust condition.
