NDOT Begins Second Season of U.S. 50 Tahoe Roadside Slope Improvements
Department Announces U.S. 50 Single Lane Closures Near Cave Rock, Tahoe For Finishing Slope Repairs
CARSON CITY, Nev. – Beginning Monday, May 7, single lane closures will be in place on U.S. 50 near Cave Rock at Lake Tahoe as the Nevada Department of Transportation completes roadside slope repairs.
In the winter of 2016-2017, numerous boulders the size of large passenger vehicles fell from a roadside slope onto eastbound travel lanes of U.S. 50 near Logan Creek Drive north of Cave Rock. Last summer, NDOT began construction of a roadside wall to reinforce and encase the approximately 60-foot high slope and help prevent future erosion. Anchor bars were drilled into the slope to secure heavy-duty mesh. The mesh was then covered with more than 1,000 yards of thick sprayable “shotcrete” concrete to create what is called a soil nail wall.
Beginning May 7, lanes will be reduced to one lane in each direction as construction crews apply the final aesthetic layer of concrete and finalize repairs to roadway surface and curbing damaged by the boulders. The concrete will be hand-sculpted to match colors and textures of nearby natural roadside slopes.
Construction is anticipated to complete, and the highway opened to two lanes in each direction, later this year.
The approximately $5 million project by contractor Road and Highway Builders will enhance safety for the more than 13,000 motorists who drive the road daily.With traffic safety as top priority, NDOT has dedicated approximately $15 million over past years to enhancing traffic safety by stabilizing roadside slopes to reduce rockslide and other erosion in U.S. 50 at Tahoe. The majority of U.S. 50 roadside slopes in the Glenbrook area have already been stabilized with rock fall netting or reinforced roadside slopes or have barrier rail/wall built at the bottom to contain and collect erosion-related rock fall. Last year, NDOT also extended the westbound, lakeside Cave Rock tunnel entrance to enhance safety by catching rock fall before it reaches the roadway.
