Paving O’Farrell Street.

Since our last construction update, Central Subway contractors have continued to make progress, completing the following work:

  • Drilling operations around Union Square to collect information about the chemical conditions of soil and groundwater
  • Installation of a decorative wrap at 933 to 949 Stockton Street, the future site of the Chinatown Station
  • Installation of a high-pressure water line on Geary Street at Stockton Street
  • Demolition of sidewalk and basement floor on the west side of Stockton Street between O’Farrell and Market streets (see above photo)

Here are some photos of our crews at work around Union Square:

In the next three weeks, crews will continue to relocate utility lines around Union Square to prepare the area for construction of the Union Square/Market Street Station. We expect all utility relocations around Union Square to be completed by June 2012. Construction is scheduled seven days a week from 7 a.m. to 7 p.m., although night work may be necessary.

The complete, current three-week construction schedule for Union Square utility relocations is available here (PDF). We also post construction, auto detour and Muni impact information on our project Google Map.

Muni Service Impacts:

While utility relocation work is in progress around Union Square, the following Muni routes may experience delays:

  • 8 Shuttle/8X/8AX/8BX Bayshore Express
  • 38/38L Geary

The 30 Stockton and 45 Union/Stockton lines have been rerouted around the Stockton Street construction site, effective Jan. 21.

Traffic Detours:

While the utility relocation work is in progress, only Muni buses, taxis, tour buses and delivery trucks will be permitted on Stockton Street between Post and Market streets.

Two traffic detour options are in place to allow for better access to the Union Square area and to aid the flow of traffic:

We appreciate your continued patience while construction is in progress.
