Sutro Tunnel. Minority Report, Reviewed

The Sutro Tunnel is a landmark in San Francisco. It was built by Adolph Sutro in 1878 and it's one of the few public tunnels in the world. The tunnel's length is 3,000 feet and its height is 25 feet. It has been described as the “eighth wonder of the world for its time” by historian Charles A. Fracchia and architect Irving Morrow described it as "the largest and most remarkable engineering project ever undertaken west of Chicago." Adolph Sutro built the tunnel to help ease traffic near Ocean Beach. The tunnel was left abandoned until 1976 by an artist group called "The Diggers." This book chronicles the history of the Sutro Tunnel and offers an insider's look into this engineering marvel.
