The Maurice J. Tobin Memorial Bridge (formerly the Mystic River Bridge) is a cantilever truss bridge that spans more than two miles (3.2 km) from Boston to Chelsea over the Mystic River in Massachusetts, United States.[3] The bridge is the largest in New England.[3] It is operated by the Massachusetts Department of Transportation and carries U.S. Route 1. It was built between 1948 and 1950 and opened to traffic on February 2, 1950, replacing the former Chelsea Bridge. The 36-foot (11 m)-wide roadway has three lanes of traffic on each of the two levels with northbound traffic on the lower level and southbound traffic on the upper level.
