State Route 49 Yuba River Washouts
Repair State Route 49 washouts at various locations along the Yuba River by installing retaining structures and rock slope prevention concrete embankment features.
PURPOSE AND NEED:
The purpose of the proposed project is to permanently repair the damaged river
embankment at four locations along the Yuba River. Temporary repairs were made to the river embankment by an emergency force account in August 2017. The sidehill viaducts will permanently restore the Yuba River washouts caused by erosion and will prevent the erosion adjacent to the Yuba River from impacting SR 49 for the foreseeable future. Currently, SR 49 is the main State highway for many neighboring cities in the Sierra and Yuba County, including Downieville and Sierraville. Construction of the sidehill viaducts will ensure that the communities surrounding the project location will have access to the state route during a significant storm event.
