Boston University Bridge

The Boston University Bridge, originally the Cottage Farm Bridge and commonly referred to as the BU Bridge, is a steel truss through arch bridge with a suspended deck carrying Route 2 over the Charles River, connecting Boston to Cambridge, Massachusetts. According to the American Association of State Highway and Transportation Officials route log, the bridge also carries U.S. Route 3 across the river to its southern terminus at U.S. Route 20 (also known as Commonwealth Avenue). However, the Massachusetts Department of Transportation does not consider the bridge to be a part of US 3; it continues the route along Memorial Drive in Cambridge until it meets Route 2A at the end of the Harvard Bridge.It was renamed for Boston University, which lies at the south end of the bridge, in 1949.ConstructionThe BU Bridge was built in 1928, on a design by Andrew Canzanelli, replacing an 1850s drawbridge known as the Brookline Bridge. Canzanelli also designed the Weeks footbridge and the first shell constructed on the Esplanade.
