Cave Rock tunnel and Highway 50 upgrades were finished one month ahead of schedule.

All travel lanes through Cave Rock are now open.

The $6 million project extended the westbound, lakeside Cave Rock tunnel entrance. The new approximately 60-foot long and 27-foot tall structure is designed to enhance safety by catching rock fall before it reaches the roadway.

Lighting and white paint were added inside each tunnel for better visibility. Two radar-activated overhead signs installed to automatically notify drivers of bicyclists or potentially icy conditions in the tunnels.
