Located on the site of the 1793 West Boston Bridge or the Cambridge Bridge, this graceful steel and granite structure was completed in 1908 with architect Edmund M. Wheelwright and William Jackson as chief engineer, and renamed to honor Henry Wadsworth Longfellow in 1927. It's also known today to locals as the "Salt and Pepper Bridge" or the "Salt and Pepper Shaker Bridge", carries Route 3 and the MBTA's Red Line across the Charles River to connect Boston's Beacon Hill neighborhood with the Kendall Square area of Cambridge. It's one of the most architecturally distinguished bridges in Massachusetts. It carries motor vehicles, public transit users, pedestrians and cyclists.
The bridge today is 2135 feet long and consists of eleven original open-spandrel steel arch spans plus two later steel girder approach spans at the Cambridge end. The bridge's substructure is built of granite block masonry and consists of ten hollow piers and two hollow abutments. The two central piers carry the signature pairs of neoclassically inspired dressed granite towers that have given the bridge its popular nickname.
This bridge was intended to rival the great bridges of Europe. Take a walk along it yourself and decide.
