• Nehalem River Bridge - Seaside OR
    Completed in 1939, the biggest bridge on what was then the newly constructed Wolf Creek Highway (now the Sunset Highway) spans the 600-foot-deep Nehalem River gorge. It eliminated a three-mile detour on this major highway between Portland and the northern Oregon coast. The concrete arch bridge cost $130,000 and was built in a cooperative effort between the US Bureau of Public Roads and the Oregon State Highway Commission. Mountain States Construction Company, a Eugene firm, built the bridge.
