The Putnam Bridge is a bridge in the state of Connecticut carrying the Route 3 Expressway over the Connecticut River, connecting Interstate 91 in Wethersfield and Route 2 in Glastonbury. It is the southernmost crossing of the Connecticut River in the Hartford Area and carries an average of 50,800 vehicles per day.[1] 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.
