Cave Rock Tunnel

The Cave Rock Tunnel is a dual bore highway tunnel on U.S. Route 50 along the eastern shore of Lake Tahoe approximately seven miles north of Stateline, in Douglas County, Nevada, United States. It passes through Cave Rock, a volcanic stone formation. To the Washoe Indian Tribe, Cave Rock is considered a sacred place and the tribe has placed restrictions on recreational activities in the vicinity of the tunnel.

The tunnels carry U.S. Route 50 through Cave Rock, a mountain along the eastern shore of Lake Tahoe. There are numerous small caves adjacent to the south portal of both tunnels which give the rock its name. The tunnel is located between the towns of Zephyr Cove and Glenbrook along the US 50 corridor. This portion of US 50 is a National Scenic Byway, part of the Lake Tahoe - Eastshore Drive. The westbound bore is 153 feet long and features exposed rock; the eastbound bore features a concrete liner and is 410 feet long. The tunnels are an elevation of at approximately 6,360 feet , about 80 feet above the level of the lake.
