Asphalt paving is underway at the Cave Rock tunnel extension project, and drivers should expect changes in the flow of traffic through the eastbound and westbound tunnels.

“Near Cave Rock the focus is all lighting and aesthetics with some final paving work to be completed,” said Nevada Department of Transportation’s Devin Cartwright.

“Work zones will be changing rapidly as we clean up the Glenbrook area and begin moving traffic back and forth between the eastbound and westbound tunnels at night for paving and lighting work. Please use caution through our work zones.”

Roadway trenching for electronics and wiring around Cave Rock is complete, and work is underway to install lighting in the tunnels.

Additionally, aesthetic work on the new tunnel has begun to blend it in with the rest of Cave Rock. This will continue through September.

The water quality improvement aspect of the project is wrapping up as well.

“Most of the new concrete barrier rail near Glenbrook has been constructed, the small remaining sections will be completed shortly,” explained Cartwright. “The drainage pipes beneath the roadway up near Glenbrook have been newly installed or if existing, repaired with pipe liners.”

Asphalt paving has begun on the shoulders near Glenbrook, as well as installation of the concrete blocks that protect drainage channel bottoms from erosion.

With three upcoming bicycle events in September, Cartwright noted that drivers should take extra caution when driving through the work zones.

On Sunday, Sept. 11, roughly 1,800 cyclists will be pedaling around the lake as part of Tour de Tahoe. A week later on Sunday, Sept. 8, another 200 bikes will be on the move for Edible Pedal. Lastly, on Sunday, Sept. 25, drivers will share the road with 50 bikes as part of OATBRAN, a week-long cycling ride across Nevada.
