Hayden Bridge, a Howe truss structure, spans the Alsea River about 2 miles (3.2 km) west of Alsea, Oregon, United States. Constructed in 1918, the 91-foot (28 m) span is one of only seven remaining covered bridges in Oregon that were built before 1920. Similar spans such as the Mill Creek Bridge crossed the Alsea or one of its tributaries in the same vicinity, but only the Hayden Bridge has survived.
