The Zion-Mount Carmel Tunnel
Construction of the 1.1 mile Zion-Mount Carmel Tunnel began in the late 1920's and was completed in 1930. At the time that the tunnel was dedicated, on July 4, 1930, it was the longest tunnel of its type in the United States. The purpose of the building the Zion-Mount Carmel Tunnel (and the Zion-Mount Carmel Highway) was to create direct access to Bryce Canyon and Grand Canyon from Zion National Park.
Long landmark tunnel cut through red sandstone cliffs, the gateway to Zion National Park.
