The Lewis and Clark River Bridge was constructed in 1924 and is the only remaining single leaf bascule drawspan in Oregon. The 85 year old bridge’s wooden support structure is built out of untreated cedar. The timber is located in a severe marine environment and subject to tidal changes of up to 12 feet daily. As a result, the timber members are showing substantial deterioration and need replacement.
This project will replace both timber approach spans of the structure.
