Nevada County, California Bridges: South Yuba River Bridges (3)

December 2012 (39.2977 Degrees, -121.0890 Degrees) South Yuba River Bridges

The old South Yuba River Crossing is an open spandrel deck arch bridge. It has tiny abutments, short approach spans, and massive fluted pier walls that support the arch ribs. It looks like the rocks under the arch supports have eroded.

Spandrel columns are at the ends of the arch and shear walls are in the center. Drop caps support the deck and you can see the outline and grain of the falsework on the underside of the deck. Ballustrade railings on top complete a very classical look to this old, reinforced concrete arch that was well worth preserving.
