Description 

Stone arch culvert carrying Mill Brook under the former B&M Lexington Branch, now the Minuteman bike path. Only the west/south face is visible; at some point in the 1940s or 50s the culvert was extended northeast.

"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.

This stone arch bridge has filled, ashlar spandrel walls, stepped wing walls, and uniformly-shaped voussoirs. The base of the arch wall has been encased in concrete. Between the crown of the arch and the tracks is a layer of fill approximately 30 feet deep." -Charles Scott, MBTA Historical Property Survey Phase II, 12/1987
