Description 

The twin tunnels were built in 1916 by blasting through solid granite. The interior was lined with timber to protect trains from falling rock. The 75 feet between them was protected by a timber snowshed. At the other end of each tunnel, a concrete arch was built as a permanent snowshed to keep snow from building up and blocking the tunnel entrance.

Tunnel 15.1 is 1,213 feet long. Tunnel 15.2 is 819 feet long.
