Four bridges have been enhanced and improved for earthquake safety and stability along Highway 395 in the Carson Valley south of Carson City, according to the Nevada Department of Transportation.
Two bridges cross the Carson River and two cross the adjacent Cradlebaugh Slough. The bridges were seismically retrofitted with approximately 20,000 pounds of reinforcing steel and other improvements as part of NDOT’s continuing effort to retrofit older bridges in the event of earthquakes.
Roughly 8,000 cubic yards of rock was also placed in the riverbed to reduce future erosion of the bridge supports, and other bridge rehabilitation and improvements made. During construction, crews placed a diversion in the river that diverted up to 2,000 cubic feet per second of river flow around areas of construction.
The $1.6 million project by contractor Granite Construction Company began in November.
