Central Subway Construction has begun

Central Subway Construction has begun at the southeast corner of Geary and Stockton. The Central Subway will be the new line connecting Chinatown, Union Square, Moscone Convention Center, the Ball Park and the south east sector of the City together. The construction will move a block at a time along the east side of Stockton street down to Market. The construction crew will then cross the street and continue up the west side from Market to Geary. When that work is done, construction will continue on the east side of Stockton between Geary and Post Street where Maiden Lane starts. It is expected that the work will take 2-3 months on each block.


ABOVE: Looking down Stockton from Post Street. The right lane allows a right turn on Geary to enter the Union Square Garage.

One lane down Stockton for buses, taxis and delivery vehicles


Construction will proceed 7 days/week, 7:00 a.m. to 7:00 p.m. One lane of traffic will remain open to buses, taxis, tour buses and delivery vehicles only.

There are two detours around the work.

Drivers will also be allowed to turn right off of Post Street onto Stockton to get to the Union Square Garage Entrance. But, others coming down Stockton from the tunnel and Chinatown will be directed down Post Street.
