LAKE TAHOE, Nev. – The Nevada Department of Transportation (NDOT) will be performing a routine inspection at Cave Rock on Tuesday, May 20, from 8 a.m. to 3:30 p.m. They will need to periodically reduce and shift the traffic lanes on US50 as they inspect the tunnels.
Drivers should expect moderate travel delays and are advised to leave extra travel time. The work schedule is subject to change based on weather and other factors.
The first of two Cave Rock tunnels was bored through the rock in 1931, with a second tunnel created in 1957. A rock slide in 2015 led NDOT to retrofit the original tunnel with a concrete liner and a 60-foot extension of the tunnel to capture falling rock.
The lane reductions are for routine, federally mandated inspections. NDOT performs routine inspections on Nevada bridges and tunnels every two years.
In fact, NDOT’s dedicated bridge inspection and rehabilitation program has helped Nevada bridges to be named the nation’s best for multiple consecutive years.
