Across Town in 7 Minutes? 4th & King Work Makes Key Central Subway Link

Friday, November 20, 2015

Thanks, San Francisco! After more than eight days of around-the-clock construction, track installation at 4th & King streets for the Central Subway was completed on time last weekend.

This is a critical link that allows us to extend the existing T Third rail line up 4th Street and then underground to the Moscone Center, Union Square and Chinatown.

With the Central Subway extension, the T Third Line is projected to be the city’s most-used Muni Metro line by 2030. Starting in 2019, riders should be able to get from the Caltrain Station at 4th and King streets to Chinatown in seven minutes. How’s that for an answer to traffic congestion? 

Here’s a glimpse of some of the many faces that were part of this recent “all-hands” effort.

The work on a key connection piece for the San Francisco Municipal Transportation Agency’s Central Subway extension of the T Third Light Rail Line started the night of Nov. 6 and went through Nov. 14. Crews worked non-stop to put in track and infrastructure that will ultimately link the northern and southern quadrants of the city’s transit system.

It was an “all-hands” effort to get the word out about the work to customers, drivers, neighbors, pedestrians and visitors to the city.

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 more than 50 percent 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. When open to the public in 2019, the Central Subway will vastly improve transit options for the residents of one of the most densely populated neighborhoods in the country, provide a rapid transit link to a burgeoning technology and digital-media hub, and improve access to a premier commercial district and tourist attractions.
