Heavy excavation equipment performs work a large utility trench at Freelon and 4th, where dual sewer lines are being installed.

Workers lower equipment into an excavated trench at 4th and Freelon, where two sewer lines are being installed.

Heads up – 4th and King Track Work

central_subway — Thu, 05 Nov 2015 22:22:32 +0000

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.

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 4^th 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 4^th 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:
