Heads up – 4th and King Track Work http://www.centralsubwayblog.com/blog/2015/11/heads-up-4th-and-king-track-work/ http://www.centralsubwayblog.com/blog/2015/11/heads-up-4th-and-king-track-work/#respond Thu, 05 Nov 2015 22:22:32 +0000 http://www.centralsubwayblog.com/blog/?p=7086 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

4thandKing_Flyer_FNL

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.

Labor Day Weekend Trackwork http://www.centralsubwayblog.com/blog/2015/09/labor-day-weekend-trackwork/ http://www.centralsubwayblog.com/blog/2015/09/labor-day-weekend-trackwork/#respond Thu, 03 Sep 2015 20:51:36 +0000 http://www.centralsubwayblog.com/blog/?p=6952 Location of future track configuration work over the Labor Day weekend.  Switches and additional tracks will be installed to prepare for construction of the surface portion of the alignment up 4th Street.

Location of future track configuration work over the Labor Day weekend

The summer of 2015 is coming to a close with a brunch of activity! The San Francisco Municipal Transportation Agency (SFMTA) is focused on projects that will make transportation safer and more reliable. In addition, BART will be shutting down the Transbay Tube for weekend track repairs. And Billy Joel is in town for a concert on Saturday, September 5 at AT&T Park.

For the Central Subway project, crews will be installing track and making infrastructure upgrades at the intersection of 4th and King Streets this Friday, Sept. 4 through Tuesday, Sept. 8. This is planned as a two phased project, with the second phase scheduled for early 2016.

Work will begin at 10p.m. Friday, September 4 and continue ‘round the clock through early morning Tuesday, September 8. Construction on Friday September 4 is anticipated to cause a significant amount of noise due to jack-hammering from 10 p.m. to 2 p.m. on Saturday as crews break into a 16-inch thick pavement at 4th and King to prepare for replacing tracks and switches.

The road work will impact Muni travel as well as people driving, walking and biking in the area. Here’s what to expect:

Muni Metro

  • Traveling Downtown from Sunnydale:
    • Daytime: Disembark from the T Third at 4th and Berry streets. Walk to the 4th and King platform and board the N Judah outbound
    • After 9:30pm: Disembark from the T Third at 4th and Berry streets. Walk to the 4th and King bus stop and board the early shutdowns bus shuttle
  •  Traveling to Sunnydale:
    • Daytime: Customers board the N Judah toward the Caltrain station between Van Ness Station and Embarcadero Station:
      • Disembark at the temporary platform at the mid-block crosswalk on King Street between 3rd and 4th streets, then
      • Connect to the southbound T Third train toward Sunnydale at 4th and Berry streets OR
      • Customers may be dropped off at the 4th and King Platform; then
    • Connect to the southbound T Third train toward Sunnydale at 4th and Berry streets
  • Americans with Disabilities Act (ADA) passengers can always choose to disembark at 4th Street. However, there will also be an ADA ramp at the temporary platform.
  • After 9:30pm: Customers board the early shutdowns bus shuttle toward the Caltrain station
    • Disembark at the 4th and King bus stop, then
    • Walk to the southbound T Third train toward Sunnydale at 4th and Berry streets
  • Traveling to Balboa Park:
    • Daytime: Board the N Judah outbound at the 4th and King Platform toward downtown:
    • Disembark between Embarcadero Station and Van Ness Station, then
    • Connect to the outbound K Ingleside toward Balboa Park
  • Customers waiting for the T Third Line between the Embarcadero and the 4th and King stations should board an N Judah train
  • After 9:30pm: Board the early shutdowns bus shuttle stops and transfer at St. Francis Circle for the on-surface M-Ocean View or K-Ingleside trains
