National Register of Historic Places in Mendocino County
The Albion River Bridge opened to traffic in 1944. Because it was built during World War II when concrete and steel were in short supply for civilian use, the bridge was built of salvaged wood treated with a copper azole preservative. It is the only remaining wooden bridge on California Route 1.
The Albion River has been crossed by a bridge since 1861. Until the present bridge was built, the crossing was low, and could be reached only by treacherous grades up and down the bluffs on either side of the river.
In 2009, the California Department of Transportation proposed to replace the bridge. Albion residents had the bridge listed on the National Register of Historic Places in an attempt to preserve it.
