Description 

"Construction of the Lexington and West Cambridge Railroad, running between the connection with the Fitchburg Railroad at West Cambridge and Lexington Center, was completed on September 1, 1846. The line was operated by the Fitchburg Railroad. An extension of the line from Lexington to Concord was completed in 1873. Passenger service on this line ended in 1977, and the track has been removed in many places. The right-of-way is currently being rebuilt as the Minuteman Bike Trail.

Ashlar stone abutments, originally built to accommodate a three track, single span bridge, now carry a single track, thru plate girder span. Bridge has riveted plate girders and floor beams and I-beam stringers, three beneath each rail. Bridge also has lower lateral cross bracing.

This is one of the bridges erected in 1905 to eliminate grade crossings on the Lexington line."
