Due to upcoming construction activity, the bus stop for the southbound 8X/8AX/8BX Bayshore Express, 30 Stockton, 45 Union/Stockton, and 91 Owl routes on Stockton Street between Washington and Jackson streets will be relocated. The new bus stop location is on the northwest corner of Stockton and Jackson streets in front of Little Paradise.
The new bus stop will continue to service the following southbound routes:
Service for these bus routes will remain as scheduled.
Due to the construction of the Central Subway, the 47 Van Ness and 83X Mid-Market Express bus stop on 4th Street between Bluxome and Townsend streets is being relocated to Townsend Street between 4th and 5th streets. The change is slated to take place on Friday, March 13.
During the sewer upgrade work, drivers will be diverted to the outermost lanes of 4th Street, between Brannan and Townsend streets. The map to the right highlights the relocation of the bus stop. This bus stop is being relocated so buses will not impede the flow of southbound traffic.
For up-to-date construction related information and a ten day look ahead, check out our Construction Update posted to our blog on Fridays.
As the Central Subway Project builds four new stations, it also upgrades utilities along the alignment. A new water line and high pressure fire hydrant was completed recently across from the future Chinatown Station.
Also in the Chinatown neighborhood, Central Subway ambassadors increase safety by guiding pedestrians at intersections on Stockton and Washington streets adjacent to the construction site.
Fridays we post the most up-to-date construction information.
On Dec. 3, San Francisco Mayor Ed Lee, the Union Square Business Improvement District, the San Francisco Municipal Transportation Agency and the Central Subway officially kicked-off “Winter Walk SF” in Union Square – an open plaza for the public to enjoy. This festive, pedestrian-friendly holiday hub runs through January 1 on Stockton Street between Ellis Street and Geary Boulevard.
More details and scheduled events can be found here.
The Central Subway Project started deploying ambassadors to assist pedestrians. This is part of a pilot program to help keep Sunday foot traffic moving in the heart of the downtown area.
We thank the businesses, residents, shoppers, and commuters of San Francisco for their continued engagement with this significant investment in the extension of our public transportation system.
On August 12, House Minority Leader Pelosi was joined by Mayor Lee and SFMTA Director Reiskin near the future site of the Central Subway Yerba Buena/Moscone Station.
Each speaker emphasized the importance of investing in mass transit. It was also noted that by building infrastructure there is an investment in San Francisco’s future generation.
The Central Subway will significantly improve the public transportation network in San Francisco and provide connections to BART, Caltrain, Muni Metro, Muni bus routes, Muni cable car lines, and in the future, high-speed rail. The T-Line extension is expected to open in 2019.
Artist Tomie Arai met with some of the San Francisco community on August 7 about her art installation for the future Central Subway Station in Chinatown. More than thirty people attended the event produced in conjunction with the San Francisco Arts Commission (SFAC) and hosted by the Chinese Culture Center (CCC). The presentation was done both in English and translated into Chinese by Cathie Lam of Chinatown Community Development Center (CCDC).
Abby Chin, curator and artistic director of CCC, welcomed the artist Tomie Arai and introduced the SFAC public art representative Mary Chou.
Ms. Chou (SFAC) described the comprehensive public art program and how it will reflect the rich cultural and historical contexts within this area (see Central Subway Arts Master Plan). As explained by Chou, the purpose of this gathering was for the artist to receive input from the community.
The location of this installation will be a wrap around the outside top entrance of the station and two platform level pieces.
Arai took the group through a series of slides that represented some of her previous art work. Much of her work has dealt with cultural identities. Her work tends to highlight and celebrate a community’s shared history. Arai’s goal is to tell a story about San Francisco’s Chinatown and her concept for her installation is “Urban Archeology.” Her vision for this art piece is to represent both the past and the present of the Chinatown community. A commemorative group photo of this important gathering can be seen below.
Father John Takahashi and Central Subway Program Director John Funghi stand beside concrete blocks that once formed the foundation of a historic North Beach church.
Earlier this month, construction crews demolishing the Pagoda Palace unearthed a long-lost piece of San Francisco history: the foundations of a church that stood on these grounds more than a century ago.
The Holy Trinity Orthodox Cathedral, now located at 1520 Green Street, once stood in North Beach at the corner of Powell Street and Columbus Avenue. Built in 1888, the dramatic onion-domed structure was completely destroyed by the great San Francisco earthquake and fire of 1906. All that remained were five bronze bells – and they survived because they were off site at the time, being repaired. The church relocated to the Green Street location soon after, opening in 1909.
Last week a concrete block from the old church’s foundations joined the bells at the Green Street cathedral. After construction crews unearthed the foundations, we contacted Father John Takahashi, the senior priest of the Holy Trinity Orthodox Cathedral, to inform him of our discovery. We also invited him to visit the construction site and see the newly uncovered relics of his church’s past.
The Holy Trinity Cathedral on Powell Street, circa 1890.
Once on site, Father John spoke with Central Subway Program Director John Funghi, and the Central Subway team gave Father John a block of concrete from the old foundations. The block will now live in the garden of the Green Street cathedral.
Central Subway crews discovered the historic foundations while dismantling the thick concrete slab that formed the base of the Pagoda Palace Theatre. Once the slab was removed, the outlines of the foundation revealed themselves amidst dirt and rubble.
Archeologists and construction personnel examined the unearthed foundations and concluded that they were consistent with building practices in the late 19th century. The absence of rebar, the consistency of the concrete and the size of the aggregate in it helped support this conclusion.
With a piece of the old church now safely preserved, crews then broke apart what remained of the foundations to make room for the next phase of Central Subway construction, and the next chapter in the life of this storied North Beach site.
San Francisco Mayor Edwin M. Lee takes a look at tunnel boring machine Mom Chung in the excavation under 4th Street where tunneling will begin.
Yesterday, Mayor Edwin M. Lee paid a visit to the construction site where tunneling will begin and saw Mom Chung, the 350-foot-long tunnel boring machine currently being assembled underground.
Speaking to reporters in front of the digging cutter head of Mom Chung, Mayor Lee said he was excited about the Central Subway, calling the T Third Line extension “one of the most important projects for the future of San Francisco.”
SFMTA Board Chairman Tom Nolan, SFMTA Director of Transportation Edward D. Reiskin, Central Subway Program Director John Funghi, key city officials and members of Central Subway team accompanied Mayor Lee under 4th Street to show him the major excavation where tunneling will begin. Check out the photos below for more on the Mayor’s visit to this important construction site.

The Central Subway tunnels will end here, at the Pagoda Palace in North Beach, under a plan to relocate the retrieval site for the project’s tunnel boring machines.
In response to community concerns about Central Subway construction in North Beach, SFMTA staff and multiple city agencies have worked for the past few months to relocate the retrieval site of the project’s tunnel boring machines (TBMs) from Columbus Avenue to the Pagoda Palace (1731-1741 Powell Street).
As we complete the administrative steps required to finalize the site change, we would like to clarify the details of the plan and respond to questions that have been raised about it. These FAQs, posted on our website, include information about the Pagoda Palace construction plan, construction impacts, the reasoning behind the change and the community’s involvement in the process.
In addition, we have prepared a memo for the SFMTA Board and our partner agencies that describes our construction plan, the lease terms for the Pagoda site, and our process in pursuing the change. You can read the memo online here.
Should you have any further questions about the Pagoda Palace plan, don’t hesitate to contact our team at email@example.com or 415-701-4371. Thank you for your continued participation as we work to improve public transit in San Francisco.

We are excited to introduce Big Alma and Mom Chung, the tunnel boring machines (TBMs) that will excavate and construct the Central Subway tunnels. Named Big Alma, after “Big Alma” de Bretteville Spreckels, and Mom Chung, after Dr. Margaret “Mom” Chung, the machines will begin tunneling later this year, starting in SoMa and heading north under 4th Street and Stockton Street through Union Square, Chinatown and North Beach. A press release about the TBMs is available online here.
The first of the machines, Mom Chung, is expected to arrive in San Francisco in April. The 300-foot-long machine will be assembled within an excavation on 4th Street between Harrison and Bryant streets and will start building the tunnel for southbound trains about two months later. Big Alma will arrive soon after Mom Chung to construct the northbound tunnel.
As tunneling proceeds, updates about the TBMs, including photos of the machines and the tunnels, will be posted on Twitter at the usernames @BigAlmatheTBM and @MomChungtheTBM. You can learn more about them on our website, at www.centralsubwaysf.com/tbm-name.

The names were selected by the public in an online poll held in January. Participants could select up to two names, one for each TBM. Of the 1,453 responses, Big Alma was the top vote-getter at 682 votes. Mom Chung took second place with 487 votes, closely followed by Firebelle Lil (451 votes), Mary Ellen (437 votes) and Juana (148 votes).
In tunneling tradition, the custom of naming TBMs is believed to bring good luck to tunneling projects. The names will remain in official use by the SFMTA and the tunneling contractor throughout the duration of the project.
“Big Alma and Mom Chung will construct San Francisco’s first new subway tunnel in decades, bringing together neighborhoods of our city that have long been in need of improved public transit,” said SFMTA Director of Transportation Ed Reiskin. “We are happy to have included the public in this exciting part of tunneling tradition. We thank everyone who voted for contributing to this important project.”
Big Alma, shown here, is still being assembled. She will arrive in San Francisco after Mom Chung to construct the northbound tunnel.
Each TBM consists of a rotating cutter wheel (the cutter head), a cylindrical steel shell (the shield) and a 300-foot train of tunnel-building mechanisms (the trailing gear). The TBMs will arrive in several parts, to be assembled at the site on 4th Street between Harrison and Bryant streets where tunneling will begin.
About the Winning Names:
“Big Alma” de Bretteville Spreckels (1881-1968): Known as “Big Alma” (she was 6 feet tall) and “The Great-Grandmother of San Francisco,” Alma de Bretteville Spreckels was a wealthy socialite and philanthropist who, among her many accomplishments, persuaded her first husband, sugar magnate Adolph B. Spreckels, to fund the design and construction of the California Palace of the Legion of Honor at Land’s End in San Francisco. A model in her youth, Spreckels was the inspiration for the “Victory” statue atop the Dewey Monument in the center of Union Square.
Dr. Margaret “Mom” Chung (1889-1959) was the country’s first female Chinese-American physician, practicing in the heart of San Francisco’s Chinatown. During World War II she “adopted” more than a thousand “sons,” most of them American servicemen, mentoring them, sending them presents and sharing meals with them during and after the war. She was also one of the earliest supporters of women in the Navy. When one of her “sons” became a congressman, he filed the first legislation to create a female branch of the Navy in response to a phone call from “Mom Chung.”
The Central Subway tunnels would end here, at the Pagoda Palace in North Beach, under a plan to relocate the retrieval site for the project’s tunnel boring machines.
The Board of Supervisors today voted unanimously to pass a key component of the plan to relocate the retrieval site for the Central Subway’s tunnel boring machines (TBMs) to the Pagoda Palace. The Board’s vote authorizes a Special Use District that will allow the owner to move forward with a previously approved development project after the building is demolished and the TBMs are extracted. You can view a press release about the vote online here.
The Pagoda Palace is the preferred location to remove the TBMs. As a result of community objections to the original plan, which involved removing the TBMs on Columbus Avenue, the SFMTA initiated a review of alternatives. Removing the TBMs at the site of the Pagoda Palace, a building that has been vacant for nearly 20 years, minimizes local construction impacts and leaves no physical impediments to a potential extension of the T Third Line to North Beach and Fisherman’s Wharf.
The retrieval site change will also require National Environmental Policy Act (NEPA) clearance by the Federal Transit Administration. If all of the necessary legislative processes and approvals occur by early April, then the demolition of the Pagoda Palace site can commence.
We will continue to update the community as the retrieval site change moves forward. Thank you for your participation in this process.

Today the Board of Supervisors voted unanimously to support a key component of the plan to relocate the retrieval site for the Central Subway’s tunnel boring machines (TBMs) to the Pagoda Palace in North Beach. The item, an ordinance to create a Special Use District (SUD) for the Powell Street property, would allow the owner to move forward with a previously approved development project after the building is demolished and the TBMs extracted. A second and final vote to approve the ordinance is expected at next week’s Board of Supervisors meeting.
To relocate the retrieval site from Columbus Avenue, the SFMTA has signed a lease with the owner of the Pagoda Palace property. The two-year lease will allow the agency to demolish the building and extract the TBMs. The state-of-the-art tunneling machines are expected to reach North Beach in 2014.
The relocation plan is undergoing review by the Federal Transit Administration for compliance with the National Environmental Policy Act (NEPA). If all of the necessary approvals occur by April 1, then the demolition of the Pagoda Palace building can then commence.
We will continue to keep the community informed as we work to respond to concerns about the original retrieval plan. Thank you for your continued participation as we work to finalize the retrieval site change.
The Central Subway tunnels would end here, at the Pagoda Palace in North Beach, under a plan to relocate the retrieval site for the project’s tunnel boring machines.
Today the Board of Supervisors Land Use Committee voted 3-0 to recommend approval of a Special Use District (SUD) for the Pagoda Palace (1731-1741 Powell Street). The SUD, a key component of the plan to relocate the retrieval site for the Central Subway’s tunnel boring machines (TBMs) from Columbus Avenue, would allow the owner of the Pagoda Palace to move forward with a previously approved development project after the building is demolished and the TBMs extracted.
Tomorrow the full Board of Supervisors will consider the SUD. This meeting will be held at 2 p.m. at City Hall, Room 250.
Under the retrieval site relocation plan, the Pagoda Palace will be demolished this spring. Central Subway crews will then prepare the site for arrival of the TBMs. The state-of-the-art tunneling machines are expected to reach North Beach in 2014.
We will continue to keep the community informed as we work to respond to concerns about the original retrieval plan. Thank you for your continued participation and patience.

Today the SFMTA Board of Directors voted unanimously to approve key components of the plan to relocate the retrieval site of the Central Subway’s tunnel boring machines (TBMs) from Columbus Avenue to the Pagoda Palace (1731-1741 Powell Street). The Board’s vote authorizes a two-year lease to utilize the Pagoda property. It also allows for the increased construction costs associated with the site change, including demolishing the existing structure and extending the Central Subway tunnels past the original site on Columbus Avenue.
The two-year lease, capped at $3.15 million, including $800,000 in rent and up to $2.35 million in ancillary fees, allows the SFMTA to demolish the existing structure and utilize the property to retrieve the TBMs. Total costs to the SFMTA, including the lease, demolition of the building and extraction of the TBMs, will not exceed $9.15 million. Additional details about the lease are available in this press release from the SFMTA.
Next week, the Board of Supervisors will consider a Special Use District (SUD) for the Pagoda Palace site. The SUD would allow the owner of the Pagoda Palace to move forward with a previously approved development project after the building is demolished and the TBMs extracted.
Members of the public may comment on the SUD at the Land Use Committee meeting.
We thank the community, Mayor Lee, Supervisor David Chiu, numerous city agencies, and the property owner for their support and cooperation throughout this process. We will continue to keep you informed as we work to finalize the retrieval site change.
The Pagoda Palace in North Beach, long considered an eyesore, will be demolished under a plan to relocate the retrieval site for the Central Subway’s tunnel boring machines.
For the past two months, SFMTA staff and multiple city agencies have been working to allow the relocation of the retrieval site of the Central Subway’s tunnel boring machines (TBMs) from Columbus Avenue to the Pagoda Palace (1731-1741 Powell Street). This effort has been undertaken in response to community concerns about construction and traffic disruption associated with the original plan.
On Wednesday the SFMTA completed lease negotiations with the owner of the Pagoda Palace. The lease, a major step forward in the agency’s efforts to relocate the retrieval site, allows for the demolition of the existing building and the use of the property to retrieve the TBMs. We thank the community, Mayor Lee, Supervisor David Chiu, numerous city agencies, and the property owner for their support and cooperation in achieving this agreement. You can view the press announcement about the lease agreement here.
Although several steps remain before the retrieval site relocation is finalized, yesterday two integral components of the relocation plan moved forward when the Planning Commission voted to approve a Conditional Use (CU) application and recommend a Special Use District (SUD) for the Pagoda Palace site. The SUD and CU would allow the owner of the Pagoda Palace to move forward with a previously approved development project after the building is demolished and the TBMs extracted.
In the coming weeks, items related to the relocation plan will be considered at the following meetings:
As always, we welcome and encourage public comment at these meetings.
We will continue to keep you informed as we work to finalize the retrieval site change. We thank you for your continued participation as we work to respond to community concerns about construction in North Beach.
