September 2017 (39.3017, -123.7921)Big River Bridge |
The history of Big River is about entrepreneurs who built sawmills, railroads, and bridges along the river to harvest and sell the forest of redwoods that once covered this region. All of that activity has disappeared without a trace.
The Big River Bridge (10 0146) is a three span box girder structure on single column bents (built in 1962) with a 190 ft long center span. In 1994 the bridge columns were wrapped in steel casings to protect them from earthquakes. Unfortunately these casings soon began to rust due to the marine environment.
