The Tobin Memorial Bridge was erected in 1948-49 and opened to traffic in 1950. It connects the Charlestown section of Boston with Chelsea. The bridge provides three travel lanes northbound on its lower level and three lanes southbound on the upper level. The 36-foot-wide roadway is bounded on both sides by safety walks (2’7″ wide) with steel-pipe railings on each side.

The main structure over the Mystic River is a three-span, cantilevered truss 1,525′ in length. Its center span is 800′ and the maximum truss height is 115′. It provides a navigable waterway opening 700′ wide by 135′ high. A smaller, simply supported warren truss spans the Little Mystic. It reaches a maximum truss height of 65′ and is 439′ long. Its navigable waterway opening measures 340′ wide by 100′ high.
