The Nevada Department of Transportation is taking preventative measures to ensure the future safety of the traveling public within the Lake Tahoe Basin. As a result of large scale rock fall that occurred in early February 2015 and due to the threat of large diameter rock fall in the future, NDOT will construct a tunnel extension / rock fall shelter on the north side of the westbound Cave Rock Tunnel. This approximately 60′ long, 27′ tall, flat-topped structure will protect the traveling public by catching falling rocks all while blending into the natural surroundings with colors, patterns, and textures matching the adjacent rock faces.
Additionally, stormwater quality improvements will be made from approximately one mile north of Cave Rock at Milepost 8.4 through Milepost 11.4. Improvements include paved shoulders, new drop inlets, new sediment filtration systems, slope scaling, and barrier rail.
