The Derby-Shelton Bridge is a road crossing over the Housatonic River in the U.S. state of Connecticut, connecting the cities of Derby and Shelton. It connects Route 34 in downtown Derby with Route 110 in downtown Shelton. The bridge and approaches are designated but not signed as State Road 712. The current bridge was built in 1918 by the Connecticut State Highway Department to replace a former steel-arch bridge built in 1891 known as the Huntington Bridge. Prior to that, an even older wooden covered bridge (built in 1857) was at this site.
