US 31–Island Lake Outlet Bridge, Bascule bridge in Charlevoix, United States.
The US 31-Island Lake Outlet Bridge consists of two 45-foot steel leaves spanning across the waterway connecting Lake Charlevoix to Lake Michigan.
The bridge opened in 1949 after construction delays during World War II, replacing a swing truss structure that had served the area since 1901.
The structure forms an essential link between the communities on both sides of the channel, supporting local transportation patterns and maritime activities.
During summer months, the bridge opens frequently for boat traffic, requiring vehicles on US Highway 31 to stop and wait for water vessels to pass.
Each leaf of the bridge contains a 73-ton concrete counterweight system that enables smooth mechanical operation when raising and lowering the spans.
