Southern portal of Hill Street Tunnel (Double Bore)

The Los Angeles-Pacfic Railway petitioned the City in 1906 to construct two single-bore tunnels; one ran up Hill from roughly First to Temple, the other from just above Temple to Sunset. They opened in September, 1909.

September 1913 saw the opening of a second bore on the southern part of the tunnel, a municipal project for pedestrians and private vehicle traffic.

As part of the Civic Center expansion, the hill was removed, the tunnels were demolished in 1955, and Hill Street flattened.
