Central Subway Construction Look Ahead
February 21, 2011 to March 6, 2011
(PDF available: Contract 1251 Feb. 21 Look Ahead)

Utility Relocation for the Union Square/Market Street Station

• Geary Street (east and west side of Stockton Street): Continuation of sewer installation
  
• O’Farrell Street (east and west side of Stockton Street): Continuation of sewer installation
• East side of Stockton Street (Geary to O’Farrell streets): Continuation of basement demolition
  

Construction is scheduled for seven days a week from 7 a.m. to 7 p.m., although night work may be necessary. Noise and dust will be kept to a minimum and the construction team will work to maintain a clean streetscape during and outside of construction hours.

The businesses along the construction route will remain open. The contractor will always maintain safe pedestrian access to all stores during business hours. Those traveling or working in the area can expect an increase in noise, dust and traffic as a result of the construction.

Standard traffic signs will be used to detour pedestrian and vehicle traffic and variable message signs have been placed on Geary Street, O’Farrell Street and Stockton Street to inform approaching traffic of detour routes. Detour signs will include directions to nearby parking garages.

Traffic Impacts

• At all times only one lane of traffic will be available on Stockton Street between Sutter and Market streets.

• The open lane of traffic on Stockton Street will be available for Muni buses, taxis, tour buses and delivery trucks only.

• All private automobiles going to 4^th Street and other SoMa destinations will be required to take one of two detours.

• Two traffic detour options will be in place to allow better access to the Union Square area and to aid the flow of traffic (see graphic at the bottom of this construction update):

o Option 1: Divert west on Sutter Street, south on Mason Street, east on Eddy Street, south on Cyril Magnin Street, continue south across Market Street onto 5th Street, east on Folsom Street and south on 4th Street or

o Option 2: Divert east on Post Street, south on Montgomery Street to New Montgomery Street, west on Howard Street and south on 4th Street.

• Parking Control Officers will be on hand to monitor traffic.

• Garages within the construction zone will be open and accessible.

Muni Service Impacts
During the utility relocation, the following Muni routes may experience delays, but will continue their normal routes on Stockton Street:

o 8X Bayshore Express
o 30 Stockton
o 45 Union-Stockton
