This notice provides a construction update and a look ahead for what to expect in the areas where we are building four new stations along the alignment. You’ll find information about work activities, traffic and transportation impacts taking place over the next two weeks at SoMa, Yerba Buena|Moscone, Union Square and Chinatown.

The second phase of trackwork installation and transit signal priority upgrades at the intersection of 4th and King began on Friday, November 6th and will be completed on Saturday, November 14.  The completion of this work is an exciting milestone in the construction of the Central Subway.   Looking down 4th Street, the first tracks that will accommodate the Central Subway’s alignment from 4th and King to Chinatown can now be seen.   This eight day project had impacts on traffic and Muni travel.  We are grateful for the public’s cooperation during the construction.  Future track installation on 4th Street will occur after utility relocation has been completed.

Construction schedules, bus routes, and stop locations are subject to change due to unforeseen conditions. Signs will be posted at affected stops to advise of service changes.

Our thanks goes out to the businesses, residents, shoppers, commuters, and all those who are touched by the Project, for their continued engagement as we work to extend the city’s public transportation system.

Heads up – 4th and King Track Work

Starting at 10pm tomorrow Friday November 6th work will begin at the intersection of 4th and King to install a new track configuration for the future surface portion of the T Third Line extension through South of Market.  Starting November 6, work will last for eight days, finishing on November 14.  This work will temporarily affect both pedestrians and motorists through the area, but also light rail operations.  Here are some major points to be aware of:

  • Light rail vehicles for the T Third Line will be replaced by buses for the duration of this work.  These buses will not be loading passengers at the existing light rail platforms along the T Third alignment, but will instead be loading nearby.  Boarding near the Caltrain Station will be located on 3rd between King and Berry.  Please be aware of signage.  Community ambassadors will help communicate proper boarding areas.
  • The E Line will be temporarily shut down.
  • The N Judah will not be boarding at the Caltrain platform.  Instead, boarding for the N Judah will be located at a temporary platform constructed at 3rd and King.
  • Bus shuttles will replace subway service every night after 9:30 pm

Motorists coming down the King Street offramp from I-280 will need to take a right turn at 5th and a left on Berry to travel through the area.  Once on Berry, drivers will be able to go through to 3rd Street, where they can make a right or left turn.  Vehicles traveling south on 4th Street will not be able to travel past King to Berry.  Both lanes on Berry will be converted to go eastbound between 5th and 3rd.  Motorists traveling west on King will not be affected.  Please take these temporary detours into consideration when traveling through the area.

A large concrete structure for the Yerba Buena/Moscone Station has been constructed under 4th Street between Folsom and Howard.  This structure, called the “station box” will eventually become the platform area where subway riders will board and depart waiting trains.

A large-diameter ventilation fan keeps the work site safe while workers maneuver temporary steel supports into place.  These supports are called “walers.”

Eventually, floors and finished walls will replace the temporary steel supports you see here.  After construction is complete, riders will begin using the station in 2019.

The second phase of track work installation and transit signal priority upgrades at the intersection of 4th and King begins Friday, November 6th at 10p.m. and continues through Saturday night November 14th.  The first phase of work was completed over Labor Day Weekend.   The completion of both phases will be a major milestone in the construction of the Central Subway.

The work will overlap with other major construction projects and have ripple effects across the city’s transportation network.   We are doing everything we can to minimize customer inconveniences but plan ahead for delays.  Avoid the Mission Bay area during construction if you can.  If not, transit, walking or biking are your best options.   Ambassadors will be onsite to direct the public as needed.   For more information, visit sfmta/4th-King.

Construction schedules, bus routes, and stop locations are subject to change due to unforeseen conditions. Signs will be posted at affected stops to advise of service changes.

Our thanks goes out to the businesses, residents, shoppers, commuters, and all those who are touched by the Project, for their continued engagement as we work to extend the city’s public transportation system.

Workers prepare track work at the 4th and King intersection over Labor Day weekend as part of the Central Subway project. The project will construct a modern, efficient light-rail line that will improve public transportation in San Francisco.

Heavy construction along the alignment, which features stops in the South of Market area, or SoMa, Yerba Buena, Union Square and Chinatown began in 2012. With 54% of the work done, and two tunnels for the trains completed, the project is currently focused on building stations and installing track and signal equipment.
