Central Subway daytime construction has been adjusted on Stockton Street in Union Square. Stockton Street between Ellis and Geary streets is open to pedestrians, but remains closed to vehicles. Union Square businesses remain open.
The Central Subway Project will construct a modern, efficient light-rail line that will improve public transportation in San Francisco. This new 1.7-mile extension of Muni’s T Third Line will provide direct connections to major retail, sporting and cultural venues while efficiently transporting people to jobs, educational opportunities and other amenities throughout the city. With stops in South of Market (SoMa), Yerba Buena, Union Square and Chinatown, 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 attraction.
Construction work will recommence in January 2018.
UPDATE: Fuel Tank Replacement at Muni Kirkland Bus Yard
Monday, December 4: The southern sidewalk on Beach Street will be reopen, the streetcar stop at Beach Street, west of Stockton Street, will resume serving the E Embarcadero and F Market Wharves lines.
Since May SFMTA crews have been working to replace two underground fuel tanks at Muni’s Kirkland Bus Yard in Fisherman’s Wharf. The work required the closure of sidewalk and relocation of the streetcar stop. This replacement project will bring the tanks up to code, improve safety and make fueling faster and more efficient. The overall construction is expected to be completed by the end of this year.
Saturday, December 2 and Next Saturday, December 9: Contractors from San Francisco Public Works will continue repaving work on Potrero Avenue between 17th and Alameda streets.
As part of the project, sewer pipes will be replaced at several intersections and overhead line infrastructure will be replaced along the corridor.
The goal of the Potrero Avenue Roadway Improvement Project is to replace aging infrastructure and to improve safety for people walking, biking, and to help beautify Potrero Avenue. This project will also revitalize public space adjacent to the San Francisco General Hospital with pedestrian safety improvement work such as sidewalk widening, new landscaping and new street lights.
This Saturday, crews will conduct repaving work on Potrero Avenue roadway between 17th and Alameda streets including the intersection.
Muni customers should expect service delays on Muni route 9 San Bruno during construction.
Crews will pave one block per day with work hours from 7 a.m. to 7 p.m.
UPDATE: Van Ness Improvement Project
The Van Ness Improvement Project is a civic improvement project that will bring San Francisco’s first Bus Rapid Transit system. To maximize the benefits of construction, the City will also be replacing major utilities including water, sewer and emergency firefighting water systems. Work will also be done to repave Van Ness Avenue, enhance streetlights and landscaping, and install new sidewalk lighting and rain gardens.
Traffic lanes on Van Ness Avenue have been shifted to create two construction zones for upcoming utility work. Because some of this work requires reducing Van Ness Avenue to one lane in each direction, some work is limited to nighttime hours. Neighbors will be notified of night noise 72-hours in advance of night work.
Sunday, December 3 through Monday, December 4: From 9 p.m., Sunday to 5 a.m., Monday, crews will work on the emergency firefighting system on Van Ness Avenue: between Vallejo and Union streets.

The Oak and Octavia Safety Project is improving safety and accessibility at the highly trafficked intersections where Octavia Boulevard meets Oak and Fell streets. Identified as a top priority through a community planning process, enhancements currently under construction include new center medians between Oak and Fell streets, as well as pedestrian bulbouts and ADA accessibility upgrades on Laguna Street. The construction project is expected to be ongoing through early December with periodic lane closures, with general work hours from 9 a.m. to 3 p.m., Monday through Friday.
For the next few weeks: 1) the center of Octavia Boulevard may be reduced to one lane in each direction as landscaping and lighting are added to the new center median; and 2) eastbound lanes on Oak Street approaching Octavia Boulevard and westbound lanes on Fell Street approaching Laguna Street may also be reduced due to sidewalk widening activities, resulting in possible delays.
Now until Further Notice: The SFMTA has resumed construction on 18th, 19th and Illinois streets, the project is expected to be completed in early 2018.
The Mission Bay Loop is a key component for San Francisco’s T Third rail line and is critical to operating the T Third Central Subway service plan. The loop provides turn-around capabilities for the T Third Street light rail line via a connection of trackway from 3rd Street to 18th, Illinois and 19th streets, which will allow the SFMTA to operate the necessary service levels needed to support current and planned growth within the eastern portion of San Francisco.
Traffic, including travelling by bike, may be affected by the construction work. All work areas will be clearly marked and there will be flaggers to help direct traffic. Traveling around and through the construction area should expect minor delays.
Since early April, the contractor has been working on the sewer infrastructure within the center of Illinois Street starting at 18th and Illinois streets. General work hours are from 8 a.m. to 5 p.m., Monday through Friday.

Traffic lanes traveling both north and south will remain open and there will be flaggers posted to help direct traffic. The northbound bike lane will be converted to a shared roadway. Expect minor delays when traveling around and through the construction area.
Local access to properties along the project site will be maintained. Sewer work is scheduled to be completed by December 2017.
