Linden Street Bridge

The Linden Street Bridge is a historic bridge on the abandoned Central Massachusetts Railroad over Linden Street (Massachusetts Route 60) in Waltham, Massachusetts. It is a riveted lattice through truss bridge, built in 1894 by the Pennsylvania Steel Company, and is one of only three such bridges left in the state. The bridge is 98 ft long and 17 ft wide, with an inside truss height of 21 ft, and rests on granite abutments. The design of the bridge was based on that of the Northampton crossing of the Connecticut River by the same railroad. This section of the Central Massachusetts Branch, and the bridge, have been out of service since the early 1990s when service to the last customer, a lumber dealer located on Emerson Road, ended.

The bridge was listed on the National Register of Historic Places in 1989. In 2022, the city was awarded a $500,000 state grant to restore the bridge as part of the Mass Central Rail Trail.
