Shimanek Bridge is the only red covered bridge in Linn County. Built in 1966, this is Linn County’s newest and longest covered span. Shimanek Bridge is an exception to the usual open-sided covered bridge design with rounded portals. Red paint, portal design and louvered windows are features similar to the original bridge, which was built in 1927. The bridge shares the white painted interior of other Linn County bridges.
