Longfellow Bridge Historic Rehabilitation

The Longfellow Bridge is a well-known Boston and Cambridge landmark. The structure, which carries both roadway traffic and rail, has recently been rehabilitated through a $305 million Design-Build Contract. Built in 1907, the bridge has become an emblem for the Commonwealth. The Rehabilitation of the Longfellow Bridge set out not only to re-establish the functionality of a critical piece of Massachusetts infrastructure, but also to preserve the original bridge aesthetic appearance. The paper below provides a brief overview of the project and a description of the steel detailing and fit up challenges which involved the installation of over 200,000 new pieces of steel.
