Lechmere Viaduct, Arch bridge across Charles River in Boston, United States.
The Lechmere Viaduct stretches 1700 feet across the Charles River, connecting Boston's West End neighborhood to East Cambridge with ten concrete arch spans.
Pennsylvania Steel Company and Holbrook, Cabot and Rollins completed the construction of this transportation structure, which opened to streetcar service in June 1912.
The bridge forms an essential part of Boston's public transportation network, carrying thousands of Green Line passengers between Cambridge and downtown Boston daily.
The viaduct underwent an $87.4 million rehabilitation project in 2020, receiving carbon fiber reinforcement and 3,500 feet of new track installation.
This structure contains a rare Strauss trunnion bascule span, which pivots upward to allow boat traffic passage through the Charles River waterway.
