The Butts Bridge carries Butts Bridge Road over the Quinebaug River in the town of Canterbury, Connecticut. It was completed in 1937 by the Fort Pitt Bridge Works company using designs by the Connecticut State Highway Department. The bridge is a single-span steel Parker truss design that typifies truss bridges of the early automotive age. It was built as part of the Highway Department's emergency relief program after the Northeast Flood of 1936. The bridge is also known as Bridge No. 1649 and carries an average of 2,300 vehicles per day as of 2011.
