Central Subway 4^th & King Track Installation: Nov. 6 – Nov. 14

We wanted to update you on the upcoming construction work at 4^th Street and King Street for Muni’s Central Subway.

This is the next phase of the T Third Line, which will connect the fast-growing eastern side of our city to SoMa, the Moscone Center, Union Square and Chinatown.

This extension is going to make the transit system work better for everyone. But first we have to build the tracks. That’s what we’ll be doing for about eight days starting Friday, Nov. 6 and continuing through Saturday, Nov. 14.

The SFMTA is doing everything possible to minimize customer inconveniences during construction. However, the work will temporarily cut access to an entire Muni rail storage facility. Because of that, we’ll be replacing T Third Line trains with buses and adjusting how other trains reach their dedicated routes.

Here’s what you need to know:

• This is the best time to do the work. It’s after the Giants’ season, before the holiday rush and over a weekend when people leave town. It will keep the subway on track to open in 2019.
• During the eight days of construction there will be major detours for automobiles in the SoMa and Mission Bay area.
• Delays and changes to Muni service will ripple across the transit network.  Plan ahead. You’ll need extra time.
• The work will coincide with several ongoing construction projects, including nightly early closure of Muni subway stations to install a new radio and emergency phone system, weekend track work in the Sunset Tunnel and a private hospital construction project that will close a portion of Van Ness Avenue over one weekend.
• You should avoid the Mission Bay area during construction if you can. If not, plan ahead for delays. Transit, walking and biking will be your best options.

WHAT TO EXPECT:
Construction is scheduled to start at 10 p.m. on Friday, Nov. 6 and continue through Saturday, Nov. 14. We’re working through Veterans Day to make transit better for everyone.

Work will include round-the-clock jackhammering and saw-cutting, which will cause construction work to be louder than normal. Ear plugs will be distributed to the surrounding neighbors.

MUNI SERVICE:
Muni

• There will be delays in start times for some service
• Buses will replace trains on the T Third Line between the Sunnydale and Embarcadero stations. Boarding and exiting will be curbside along the route. Stop near 4th and King streets will be at 3rd and Berry streets about one block from existing T Third platform.
• The E Line, which runs on weekends, will not run Nov. 7-8 or Nov. 14-15
• The F Line towards Fisherman’s Wharf will start about 45 minutes later
• The N Line will stop at a temporary platform on King Street between 3^rd and 4^th streets. Some delays are likely.
• The K line will operate between Balboa Park and Embarcadero only. It will not continue on to become the T Line at Embarcadero Station. Customers traveling to destinations between Embarcadero Station and 4^th and King Streets will need to transfer to the N Judah or the T bus shuttle at Embarcadero Station. Customers heading to destinations south of 4th and King should transfer to the T bus shuttle.
• Bus shuttles will replace subway service every night after 9:30 p.m. because of an ongoing construction project installing a new radio and emergency phone system. Buses will run between the Embarcadero and St. Francis Circle until the end of service at 1:30 a.m. Regular rail service will still operate at outer stops.
• Bus shuttles will replace N Line rail service between Ocean Beach and Church & Duboce from 5 a.m. Saturday until end of service on Monday on the weekends of Nov. 7 and Nov. 14 because of Sunset Tunnel construction.

Caltrain

• Caltrain customers heading downtown are encouraged to take the 10, 30, 45, 81X or 82X Muni bus lines
• 81X, 82X ( which operate during peak hours) will be running from a new temporary stop on Townsend Street between 3^rd and 4^th streets

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 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.
