One & half miles west of the town of Alsea, off Hwy 34. Hayden Bridge spans the Alsea River. It was built in 1918 and is currently in use. The span was either partially or totally rebuilt in 1945. Its portals, once rounded in design, have been enlarged to a more modern design to facilitate larger loads. Vertical board and batten siding flares out at the base, similar to Lincoln County covered spans. A daylighting window strip below the roofline on both sides of the bridge illuminates the interior.
