As Linn County's newest and longest covered span, the Shimanek Bridge offers an exception to the usual open-sided structure with rounded portals.
Red paint, portal design and louvered windows are features similar to the former span, which was built in 1927, and found on no other bridge in Linn County. Rods in the truss are grouped into a series of four instead of the usual three at each compression joint. The bridge shares the white painted interior of other Linn County bridges.
