Trinity River Corral Bottom Road Bridge

CLIENT County of Trinity

Location Trinity County

Shannon & Wilson provided geotechnical design services for the replacement of this existing four-span, 350-foot long bridge on the Trinity River. The bridge is located off State Route 299 in Big Bar, California, west of Weaverville, California.

The replacement bridge is a 450-foot-long, 42-foot-wide, slant-pier bridge, with two 12-foot travel lanes and four-foot shoulders. The new alignment is downstream of the existing bridge, requiring new embankments and cut slopes to accommodate the new roadway geometry.

Field services include coordinating with the US Forest Service, Caltrans, California Fish and Wildlife, the Wintun Nation, Trinity County DOT, cultural and biological resources monitors, and the local Trinity School District.
