US 31–Island Lake Outlet Bridge The US 31–Island Lake Outlet Bridge is a double-leaf bascule bridge in downtown Charlevoix, Michigan, that carries U.S. Route 31 (US 31, Bridge Street) across Island Lake Outlet (also known as the Pine River Channel). It is the fifth bridge to cross the channel there with the first being a pedestrian-only structure that was built in the nineteenth century. The bridge was planned in 1940, but World War II delayed the acceptance of bids until 1947. Construction finished in 1949 and the bridge opened to traffic in late June of that year. The bridge is part of the National Highway System.
