Salesforce Transit Center

File:Salesforce Transit Center main entrance.jpg.]]

Designed by Pelli Clarke Pelli Architects (PCPA), the Salesforce Transit Center is about {{convert|1430|feet}} long and {{convert|165|feet}} wide. It occupies the entire block between Minna and Natoma Streets (just southeast of Mission Street), and stretches from Beale Street to {{convert|140|feet}} east of 2nd Street. The first phase of the project includes the aboveground structure plus a belowground shell for the second phase. The structure has four levels: the ground floor with entrances, retail space, ticketing, and Muni/Golden Gate Transit boarding platforms; the second floor with retail space, food hall, offices, and Greyhound ticket counter and waiting room; the bus deck with bus bays surrounding a central waiting area; and the {{convert|5.4|acre|adj=on}} rooftop park.

The bus deck has a dedicated highway ramp (consisting, in part, of a cable-stayed bridge) to the San Francisco–Oakland Bay Bridge and an off-site bus storage facility under the western Bay Bridge approach. In order to allow buses with doors on the right to serve the central (island) platform on the bus deck, buses circulate clockwise (i.e., driving on the left) while inside the terminal. The bus bridge includes a traffic light to facilitate the transition between right-hand traffic (outside the transit center) and left-hand traffic (inside the transit center).{{Cite news|url=https://www.mercurynews.com/2018/08/29/overwhelming-awesome-riders-review-new-transbay-transit-center/|title='Overwhelming,' 'awesome:' Riders review new Transbay Transit Center in San Francisco|last=Baldassari|first=Erin|date=2018-08-29|work=The Mercury News|access-date=2018-08-30|language=en-US|archive-date=August 13, 2024|archive-url=https://web.archive.org/web/20240813214600/https://www.mercurynews.com/2018/08/29/overwhelming-awesome-riders-review-new-transbay-transit-center/|url-status=live}}

The second phase of the project, constructed as part of the Downtown Rail Extension (now known as The Portal), will add a two-level underground train station to be served by Caltrain and California High-Speed Rail. The platform area will have three island platforms serving six tracks. A mezzanine with ticketing and waiting areas will be located above the platform and below the ground-level entrances. A pedestrian tunnel was planned to be constructed below Beale Street to Embarcadero station, connecting the Transbay Transit Center with BART and Muni Metro.{{cite web |last=Robinson |first=Melia |title=San Francisco's new $2.3 billion transit center could be the most expensive bus terminal in the world |newspaper=Business Insider |date=November 2016 |url=http://www.businessinsider.com/san-francisco-transbay-transit-center-tour-2016-11/#built-in-1939-the-transbay-terminal-served-26-million-passengers-annually-during-its-heyday-at-the-end-of-world-war-ii-when-gas-rationing-ended-in-the-40s-traffic-petered-out-1 |access-date=May 23, 2017 |archive-date=June 19, 2018 |archive-url=https://web.archive.org/web/20180619035957/http://www.businessinsider.com/san-francisco-transbay-transit-center-tour-2016-11/#built-in-1939-the-transbay-terminal-served-26-million-passengers-annually-during-its-heyday-at-the-end-of-world-war-ii-when-gas-rationing-ended-in-the-40s-traffic-petered-out-1 |url-status=live }}{{cite web |first=Eric |last=Cordoba |title=Major Capital Projects Update – Transbay Transit Center and Downtown Rail Extension |date=September 14, 2016 |publisher=San Francisco Country Transportation Authority |url=http://www.sfcta.org/sites/default/files/content/Executive/Meetings/pnp/2016/09-Sep/Capital%20Projects%20Update%20-%20Caltrain%20Downtown%20Extension%20%28DTX%29.pdf |access-date=May 23, 2017 |archive-date=November 7, 2017 |archive-url=https://web.archive.org/web/20171107022313/http://www.sfcta.org/sites/default/files/content/Executive/Meetings/pnp/2016/09-Sep/Capital%20Projects%20Update%20-%20Caltrain%20Downtown%20Extension%20%28DTX%29.pdf |url-status=dead }} This was later scrapped as a cost-saving measure.{{Cite news|last=King|first=John|date=18 January 2023|title=High-speed rail to downtown S.F. is back on track — but the price tag keeps going up|url=https://www.sfchronicle.com/sf/article/high-speed-rail-transit-17724143.php|work=San Francisco Chronicle|access-date=15 July 2023|archive-date=July 16, 2023|archive-url=https://web.archive.org/web/20230716062618/https://www.sfchronicle.com/sf/article/high-speed-rail-transit-17724143.php|url-status=live}} The proposed second Transbay Tube, which may be used by Caltrain, CAHSR, and/or BART, may also connect to the Transit Center.{{cite news |url=http://www.sfgate.com/bayarea/article/BART-S-NEW-VISION-MORE-BIGGER-FASTER-2584901.php |title=BART's New Vision: More, Bigger, Faster |last=Cabanatuan |first=Michael |date=June 22, 2007 |newspaper=San Francisco Chronicle |page=A1 |access-date=November 1, 2016 |archive-date=June 19, 2018 |archive-url=https://web.archive.org/web/20180619062952/https://www.sfgate.com/bayarea/article/BART-S-NEW-VISION-MORE-BIGGER-FASTER-2584901.php |url-status=live }} This extension would cost as much as $6{{nbsp}}billion on top of the $2{{nbsp}}billion already spent, and is currently unfunded.

File:AC Transit buses at Transbay Terminal (21284664895).jpg

The original Transbay Terminal opened in 1939 to serve Key System and East Bay Electric Lines commuter trains and Sacramento Northern Railway interurban trains operating over the new Bay Bridge. It was converted to a bus terminal in 1958 and began serving AC Transit commuter buses. The structure was damaged in the 1989 Loma Prieta earthquake, necessitating replacement.

In 1995, Caltrain agreed to study extending its commuter rail service from its Fourth and King terminus closer to the Financial District, including whether the obsolete Transbay Terminal should be removed, remodeled, or rebuilt.{{cite news|url=http://www.sfgate.com/default/article/CalTrain-moves-a-step-closer-to-Financial-District-3137905.php|title=CalTrain moves a step closer to Financial District|last=Mitchell|first=Eve|date=August 4, 1995|work=San Francisco Chronicle|access-date=April 11, 2013|archive-date=February 2, 2014|archive-url=https://web.archive.org/web/20140202231220/http://www.sfgate.com/default/article/CalTrain-moves-a-step-closer-to-Financial-District-3137905.php|url-status=live}} Ultimately, it was decided that the Transbay Terminal should be rebuilt, with the rail extension entering the Terminal under Second Street. In November 1999, San Francisco voters adopted Proposition H declaring that Caltrain shall be extended downtown into a new regional intermodal transit station constructed to replace the former Transbay Terminal. The Transbay Joint Powers Authority (TJPA) was founded in 2001 as the administrative joint powers authority for the project.{{cite web

In 2006, developers agreed to a new Mello-Roos tax district in the area surrounding the Transbay Transit Center in order for permits for higher buildings to move forward. San Francisco set the tax rate in 2012 at 0.55 percent of assessed value; due to rising real estate prices, however, the 2014 tax burden had risen by nearly 50% compared to the 2012 tax burden, and the developers threatened to pull their building plans entirely or sue the city.{{cite news |url=http://www.sfgate.com/realestate/article/How-Transbay-Transit-Center-deal-s-collapse-5779101.php |title=How Transbay Transit Center deal's collapse would alter S.F. |author1=Coté, John |author2=Dineen, J.K. |date=25 September 2014 |newspaper=San Francisco Chronicle |access-date=28 March 2016 |archive-date=August 18, 2018 |archive-url=https://web.archive.org/web/20180818150717/https://www.sfgate.com/realestate/article/How-Transbay-Transit-Center-deal-s-collapse-5779101.php |url-status=live }} The lawsuits never materialized, however.{{cite news |url=http://www.sfgate.com/bayarea/article/Developers-drop-threats-over-special-Transbay-tax-6063114.php |title=Developers drop threats over special Transbay tax district |author=Dineen, J.K. |date=4 February 2015 |newspaper=San Francisco Chronicle |access-date=28 March 2016 |archive-date=August 18, 2018 |archive-url=https://web.archive.org/web/20180818115313/https://www.sfgate.com/bayarea/article/Developers-drop-threats-over-special-Transbay-tax-6063114.php |url-status=live }}

A Metropolitan Transportation Commission (MTC) peer review panel investigated whether the cracks may have been caused by flaws that developed in the steel during fabrication, plus by stress concentrations arising from weld access holes or weld termination holes cut into the beams, that were added after the shop designs were submitted for approval.{{Cite web|url=https://www.enr.com/articles/46576-contractors-defend-work-at-troubled-salesforce-transit-center|title=Contractors Defend Work at Troubled Salesforce Transit Center|last=Post|first=Nadine M.|date=March 27, 2019|website=Engineering News-Record|language=en|access-date=2019-03-31|archive-date=August 13, 2024|archive-url=https://web.archive.org/web/20240813214617/https://www.enr.com/articles/46576-contractors-defend-work-at-troubled-salesforce-transit-center|url-status=live}} Weld access holes have more stringent building code requirements than weld termination holes, and it was not clear which type of holes were added.

Numerous other transit services converge into downtown San Francisco with stops nearby. These include BART and Muni Metro at Embarcadero station and Montgomery Street station, Golden Gate Transit peak-only routes (with stops on Fremont Street), Muni bus and streetcar routes, SamTrans routes 292 and 397, AC Transit route 800, and the Presidio Go Shuttle.{{cite web |url=http://www.actransit.org/wp-content/uploads/STC-stops.pdf |title=Transit Stops: Salesforce Transit Center |date=August 5, 2019 |publisher=Metropolitan Transportation Commission |access-date=January 21, 2020 |archive-date=August 9, 2020 |archive-url=https://web.archive.org/web/20200809161224/http://www.actransit.org/wp-content/uploads/STC-stops.pdf |url-status=live }} {{As of|January 2020}}, Amtrak Thruway buses also use a surface stop outside the terminal — despite previous plans to use the bus deck — due to disagreements between the TJPA and other agencies about costs.{{cite news |url=https://sf.streetsblog.org/2020/01/16/amtrak-non-grata-at-transit-center/ |title=Amtrak Non Grata at Transit Center |newspaper=Streetsblog SF |date=January 16, 2020 |first=Roger |last=Rudick |access-date=January 20, 2020 |archive-date=January 17, 2020 |archive-url=https://web.archive.org/web/20200117154939/https://sf.streetsblog.org/2020/01/16/amtrak-non-grata-at-transit-center/ |url-status=live }}

{{Further|The Portal (San Francisco)}}

The Transbay Transit Center project was designed to include a tunnel (the Downtown Rail Extension, now known as The Portal) extending the terminus of the Caltrain commuter rail line from its current location at Fourth and King Streets; the downtown Caltrain extension is projected to alleviate roadway traffic and Caltrain rider delays, resulting in an estimated $20 million savings per year.{{cite report|chapter-url=http://transbaycenter.org/uploads/2009/11/FEIS_Ch1.pdf|title=Final EIS/IER Transbay Terminal/Caltrain Downtown Extension/Redevelopment Project|date=15 June 2004|pages=1–12|quote=Relocating Caltrain’s San Francisco terminus to the Transbay Terminal area has been projected to result in a seven percent reduction in the number of person hours of auto travel. Morning peak hour delay would be expected to be reduced by 20 percent. Implementation of the Caltrain Extension would result in daily travel time savings of 7,200 person hours, which includes 5,700 person hours saved for Caltrain riders and 1,500 person hours for roadway travelers in the corridor. Using FTA procedures, this represents an approximate $20 million per year savings (7,200 hours/day x $11.26/hour x 250 work days/year).|access-date=28 March 2016|chapter=1: Purpose and Need for the Project|website=Transbay Transit Center|archive-date=February 11, 2011|archive-url=https://web.archive.org/web/20110211033740/http://transbaycenter.org/uploads/2009/11/FEIS_Ch1.pdf|url-status=live}} The Caltrain extension depends on the electrification of its rolling stock, which was completed in 2024.https://www.caltrain.com/news/caltrain-commences-fully-electrified-service When this project is completed, Caltrain riders would no longer need to transfer to Muni to reach the downtown financial district. The heavy rail portion of the terminal would be designed to accommodate the planned high speed rail from Los Angeles, which shares the right-of-way (Peninsula Corridor) with Caltrain between San Francisco and San Jose. BART has expressed interest in having their proposed Second Transbay Tube connect to the new terminal and Alameda.{{cite news|url=http://www.sfgate.com/cgi-bin/article.cgi?file=/c/a/2007/06/22/MNGJQQJVSD1.DTL|title=BART's New Vision: More, Bigger, Faster|last=Cabanatuan|first=Michael|date=22 June 2007|newspaper=San Francisco Chronicle|access-date=2008-04-17|pages=A-1|archive-date=October 10, 2007|archive-url=https://web.archive.org/web/20071010014440/http://www.sfgate.com/cgi-bin/article.cgi?file=%2Fc%2Fa%2F2007%2F06%2F22%2FMNGJQQJVSD1.DTL|url-status=live}}

DTX was planned to open for rail service in 2019 at a budgeted cost of {{US$|2600000000|2013|round=-8}}. The DTX scope also includes moving the existing 4th & King Caltrain station underground.{{cite web|url=http://transbaycenter.org/project/downtown-rail-extension|title=Downtown Rail Extension (DTX)|author=|date=2015|website=Transbay Transit Center|access-date=28 March 2016|archive-date=September 9, 2017|archive-url=https://web.archive.org/web/20170909002720/http://transbaycenter.org/project/downtown-rail-extension|url-status=live}} Part of the DTX project also includes building out two below-grade levels below the TTC. One level would serve as the actual train platform, hosting six tracks and three platforms to accommodate Caltrain and HSR service. The other level would be a passenger waiting area, including ticket sales and retail amenities. The waiting area would be connected via tunnel to the BART/Muni Metro Embarcadero Station.

{{As of|May 2024}}, the extension is projected to cost $8.25 billion and start construction in 2025 with a completion date in 2032. A federal funding pledge covers $3.4 billion of the cost, provided that local officials identify matching funds. The project would include a three-block underground concourse connecting to BART and Muni Metro trains at Embarcadero station.{{cite news |last1=Cano |first1=Ricardo |title=S.F.'s massive plan to create a 'Grand Central Station of the West' wins major funding grant |url=https://www.sfchronicle.com/sf/article/s-f-transit-center-19471146.php |access-date=22 May 2024 |work=San Francisco Chronicle |date=22 May 2024 |archive-date=May 23, 2024 |archive-url=https://web.archive.org/web/20240523061313/https://www.sfchronicle.com/sf/article/s-f-transit-center-19471146.php |url-status=live }}
