The Waldo Grade Tunnel is currently unofficially named for William Waldo, a Whig politician who unsuccessfully ran for governor of California in 1853.
The tunnel is famous for connecting the Golden Gate Bridge to Marin County and because of its iconic rainbow paint outline.
In addition, Williams’ film Bicentennial Man features a futuristic look at the Golden Gate Bridge with the tunnel in view (albeit a far-off view), still intact.
