Alsea Bay Bridge

The bridge extends 2,910 feet across Alsea Bay, featuring a 450-foot main span with a vertical clearance of 70 feet above the water.

Constructed in 1991 to replace the original 1936 structure, this modern bridge incorporates advanced engineering methods to prevent corrosion in the coastal environment.

The bridge maintains the transportation legacy of the Oregon Coast Highway, connecting communities and supporting regional economic development since its construction.

The structure includes wider lanes and enhanced safety features, allowing vehicles to cross Alsea Bay while maintaining maritime traffic underneath.

Engineers designed the bridge with thicker concrete piers and latex-modified materials to achieve a projected lifespan between 75 and 100 years.
