Central Subway: Slowed by COVID-19 But Still Making Progress
By Phillip Pierce
The Central Subway is a transformational transportation project that will extend the T Third underground to Chinatown through some of the busiest and densest parts of our city. While this mega-project is nearing completion, we are unfortunately delayed a few months due to COVID-19 and other complexities.
Before the pandemic, we anticipated that construction would be finished by the end of next month, with customers riding trains at the start of revenue service a year later. Our current projections put the completion of construction this spring and the start of service in the following spring of 2022.

The main reasons for this delay:
-
Moving to remote work and instituting necessary safety measures and procedures during COVID-19
-
Quarantining multiple contractor crews when, despite safety measures, some of the team tested positive for COVID-19
-
Difficulties and delays in getting materials from suppliers during COVID-19
-
Ongoing design changes throughout the project due to the differing site conditions discovered deep underground
These delays will likely have impacts on the overall project budget, and we are working closely with our construction contractors to get the project completed as safely and prudently as possible.
Highlights and Making Progress

Most importantly for our neighbors, the most disruptive construction is far behind us. The streets and sidewalks along Stockton Street in Union Square and Chinatown are reopened and most work is now deep underground. The last remaining closed street – one block of Washington Street in Chinatown - will be reopened around the end of the year.
The vast majority of the project is now completed. The tunnels and tracks are done with crews now working on the final finishes, installing art and systems like automatic train control cabling, traction power and communications.
We even added a ceremonial “Golden Spike” on 4th Street joining the new Central Subway railwith the existing T Third rail line. A golden spike was first used to celebrate when the rails from the east and west come together on the First Transcontinental Railroad – a tradition that many projects follow to this day.
The project is a finalist for two International Tunneling Association Awards. The Chinatown–Rose Pak Station is a "Project of the Year” contender. The Union Square/Market Street Station’s innovative design for the battered drilled shafts support system are also nominated.
Crews have installed some of the public art – including a kinetic sculpture at 4th and Brannon station, granite etchings inside Yerba Buena/Moscone (photo above) and a light installation at Union Square/Market Street.

Central Subway Facts
Once in operation, the Central Subway will greatly reduce travel times and increase capacity along the congested Stockton Street and 4th Street corridor while enhancing connections to BART, Muni Metro, Chase Center, Oracle Park and Caltrain.
The Central Subway route starts across from Caltrain at King Street, runs along 4th Street on surface, transitions into underground tunnels with a portal under the I-80 freeway, the tunnel crosses under the BART and Muni Metro tunnels beneath Market Street, and continues under Stockton Street to Washington Street. With an above ground stop in SoMa at 4th and Brannan, and subway stations at Yerba Buena/Moscone Center, Union Square/Market, and Chinatown – Rose Pak, the Central Subway will vastly improve transit access for the residents in areas of the city, such as Chinatown, that have limited transportation options.
By extending the T Third line, the Central Subway will not only make new connections, but will also increase overall service in Visitacion Valley, the Bayview, and Dogpatch neighborhoods.

New Bayview-Hunters Point Bus Express Route Alternatives: Vote by November 15
By Enrique Aguilar
In response to deep community engagement, the SFMTA's FY 2021-22 Muni Service Equity Strategy and the Southeast Muni Expansion Project recommended adding express service from the Bayview to Downtown. The disproportionate impacts of COVID-19 on people of color and low-income people has made fast-tracking this service even more important. We are asking for feedback to help us identify the future route of this crucial new service.
This new express bus service aligns with our transportation priorities as we respond to and recover from the pandemic. Adding capacity to routes that help San Franciscans make essential trips and prioritizing neighborhoods with high concentrations of essential workers and those most impacted by the pandemic are goals in SFMTA’s Transportation Recovery Plan (TRP). This effort also minimizes travel time to reduce how long customers are in our vehicles, which are goals in our SFMTA’s Transportation Recovery Plan.
The proposed route options are estimated to take about 36 to 45 minutes one-way from end to end. The new express route from Bayview-Hunters Point would improve access to downtown, provide shorter travel times and reflect the priorities of neighborhood residents.
Proposed route alternatives for Bayview Hunters Point Express
How We Came Up With the Options
Due to the pandemic, the SFMTA project team formed a virtual Working Group that was instrumental in shaping the three route options. Members of the Working Group were:
-
Alyssa Jones Garner (CCSF)
-
Earl Shaddix (Economic on Third, EDoT)
-
Emily Rogers-Pharr (PUC)
-
Frank Martinez (BMAGIC)
-
Juanita Washington
-
Lyslynn Lacoste (BMAGIC)
-
J.R. Eppler
-
Nicole Christian (SFMTA)
-
Raina Johnson
The Working Group identified key priorities, downtown destinations customers wanted access to and providing other critical information to help the project team engage the greater Bayview Community to make a final decision.
Signs posted at neighborhood businesses and Muni bus stops on 3rd Street.
Please take our survey and vote on your preferred route alternative. The survey will be open until Sunday, November 15. Project staff will review feedback from the Bayview community and a final route identified.
