Traffic Alert: US50 to be reduced to single lanes at Cave Rock tunnel

Lighting repairs will be made inside the Cave Rock tunnel at Lake Tahoe on Tuesday, June 25 and possibly continuing into Wednesday.

Traffic on US50 at the tunnel will be reduced to one lane in each direction between 7:00 a.m. and 3:00 p.m. Repairs will be made to tunnel lighting damaged in prior traffic crashes. Motorists are advised of the potential of similar lane reductions taking place on Wednesday, if needed, to complete lighting repairs.

Westbound lanes will be rerouted to travel one lane in each direction through the eastbound Cave Rock tunnel, with reduced speed limits and some limited travel delays to be expected. While bicyclists and oversize and over-dimensional semi-trucks will be allowed through the work zone, alternate bicycle and truck routes are advised if possible.

The tunnel underwent a major renovation in 2016 when a $6M NDOT project was completed to extend the tunnel and stabilize the rocks above the entrance after boulders found their way onto the road.
