4th Street Tunnel, Of The Central Subway, SFMTA MUNI Metro, Forth Street Extension, San Francisco, California
|
The tunnel entry emerged from under the Central Freeway. It supported two tracks so was wide enough to reduce the roadway by
two traffic lanes. Street lights had already been erected, but there was no sign of track or overhead electric wires yet.
