The bridge was built in the late 1950s as part of the Route 3 connector between Interstate 91 and Connecticut Route 2. It originally terminated at Main Street in Glastonbury, rather than at Route 2. It was expected to be expanded to a double-decker in the early 1970s as part of the planned Interstate 491, a southeastern bypass around Hartford from Wethersfield to East Hartford. However, the project was cancelled in 1973. In the late 1980s, the expressway portion of Route 3 was extended to terminate at Route 2.
In 2013, the bridge underwent a $15 million rehabilitation project, which repaved the roadbed, repainted the girders, added new lighting fixtures and a new pedestrian walkway.
