History

The Longfellow Bridge was built in 1906 and was originally known as the Cambridge Bridge, but was later renamed in 1927 to honor Henry Wadsworth Longfellow, who lived in Cambridge and was a prominent figure in American literature, along with other notable authors such as Ralph Waldo Emerson, Nathaniel Hawthorne, and Edgar Allan Poe. The bridge was designed by Edwin L. Norris and Henry G. Pearson, and was constructed by the Boston Bridge Works company, with materials and labor provided by United States Steel Corporation and American Bridge Company. The bridge's construction was a significant engineering feat, requiring the use of caissons and cofferdams to build the foundation in the Charles River, and was overseen by the United States Army Corps of Engineers and the Massachusetts State Legislature. The bridge has undergone several renovations and repairs over the years, including a major rehabilitation project in the 2010s, which was funded by the Federal Highway Administration and the Massachusetts Department of Transportation.

Design_and_Construction

The Longfellow Bridge is a steel rib arch bridge with a total length of 1,746 feet and a width of 105 feet, and is supported by four piers and two abutments, which are founded on granite bedrock and concrete footings. The bridge's arches are made of steel and are filled with concrete, and the bridge's deck is made of asphalt and concrete, with a drainage system designed by Parsons Corporation and AECOM. The bridge's design is notable for its use of ornamental ironwork and masonry, which was crafted by skilled artisans from Italy and Greece, and features lamps and benches designed by Olmsted Brothers and Frederick Law Olmsted. The bridge's construction required the use of cranes, derricks, and winches, and was built using traditional craftsmanship and modern engineering techniques, with input from MIT and Harvard University.

Rehabilitation_and_Renovation

In the 2010s, the Longfellow Bridge underwent a major rehabilitation project, which included repairs to the bridge's structure, deck, and superstructure, as well as the replacement of the bridge's electrical and mechanical systems, which were designed and installed by Bechtel Group and Fluor Corporation. The project also included the installation of new pedestrian and bicycle facilities, including ramps and elevators, which were designed by Perkins+Will and Skidmore, Owings & Merrill. The project was managed by the Massachusetts Department of Transportation and was funded by the Federal Highway Administration and the Massachusetts State Legislature, with additional funding provided by the City of Boston and the City of Cambridge. The rehabilitation project was completed in 2018 and has improved the safety and accessibility of the bridge for all users, including commuters from Somerville, Medford, and Arlington, Massachusetts.
