The City and County of San Francisco, the [[AC Transit|Alameda – Contra Costa Transit District]] (AC Transit), and the [[Peninsula Corridor Joint Powers Board]] ([[Caltrain]]) proposed{{when|date=August 2018}} to replace the underused original Transbay Terminal with an entirely new and more functional building at roughly the same location.  The final [[Environmental Impact Report]] (EIR) was published in 2004,<ref>{{cite web |url=http://transbaycenter.org/documents/final-eiseir |title=Final EIS/IER Transbay Terminal/Caltrain Downtown Extension/Redevelopment Project |date=15 June 2004 |website=Transbay Transit Center |accessdate=28 March 2016 |archive-date=August 3, 2016 |archive-url=https://web.archive.org/web/20160803204906/http://transbaycenter.org/documents/final-eiseir |url-status=dead }}</ref> and construction began in August 2010 on Phase 1, the new Transbay Transit Center (TTC) building. A new outdoor temporary terminal was opened nearby to serve commuters during construction of the new transit center.

The last bus departed the Transbay Terminal early on {{end date|2010|08|07}}, just after ownership of the building was transferred from [[California Department of Transportation|Caltrans]] to [[Transbay Joint Powers Authority|TJPA]].<ref name=SFG-20100806>{{cite news |url=http://www.sfgate.com/news/article/Crews-to-ready-Transbay-Terminal-for-demolition-3179252.php |title=Crews to ready Transbay Terminal for demolition |author=Cabanatuan, Michael |date=6 August 2010 |newspaper=San Francisco Chronicle |accessdate=25 March 2016 }}</ref> Demolition by [[wrecking ball]] commenced in December 2010,<ref>{{cite news |url=http://www.sfgate.com/news/slideshow/Demolition-of-Transbay-Terminal-33555.php |title=Demolition of Transbay Terminal |author=<!--Staff writer(s); no by-line.--> |date=3 December 2010 |newspaper=San Francisco Chronicle |accessdate=25 March 2016 }}</ref><ref>{{cite news |url=http://www.sfgate.com/news/article/Wrecking-ball-begins-Transbay-Terminal-demolition-2454534.php |title=Wrecking ball begins Transbay Terminal demolition |author=<!--Staff writer(s); no by-line.--> |date=4 December 2010 |newspaper=San Francisco Chronicle |accessdate=25 March 2016 }}</ref> and demolition was declared complete on {{end date|2011|09|07}}.<ref>{{cite web |url=http://abc7news.com/archive/8345530/ |title=Demolition of old Transbay Terminal complete |author=Tyler, Carolyn |website=ABC7 News |accessdate=25 March 2016 |date=7 September 2011}}</ref>

It was announced in March 2011 that a sculpture to be assembled from Transbay Terminal debris by Tim Hawkinson would be erected on the corner of Mission and Fremont Streets after completion of the new Transbay Transit Center.<ref>{{cite press release |url=http://www.sfartscommission.org/pubartcollection/pubart-press-releases/2011/03/10/new-sculpture-by-tim-hawkinson-to-be-installed-at-the-new-transbay-transit-center/ |title=New Sculpture by Tim Hawkinson to be Installed at the New Transbay Transit Center |author=<!--Staff writer(s); no by-line.--> |date=10 March 2011 |publisher=San Francisco Arts Commission |accessdate=25 March 2016 |archive-date=April 8, 2016 |archive-url=https://web.archive.org/web/20160408053012/http://www.sfartscommission.org/pubartcollection/pubart-press-releases/2011/03/10/new-sculpture-by-tim-hawkinson-to-be-installed-at-the-new-transbay-transit-center/ |url-status=dead }}</ref><ref>{{cite web |url=http://transbaycenter.org/artists/tim-hawkinson |title=Public Art: Tim Hawkinson |date=2011 |author=<!--Staff writer(s); no by-line.--> |website=Transbay Transit Center |accessdate=25 March 2016 |archive-date=March 9, 2016 |archive-url=https://web.archive.org/web/20160309132451/http://transbaycenter.org/artists/tim-hawkinson |url-status=dead }}</ref> However, the sculpture project was cancelled on June 7, 2017 due to cost and engineering concerns.<ref>{{cite news|url=https://ww2.kqed.org/news/2017/06/08/city-of-sf-cancels-multimillion-dollar-transbay-terminal-art-project/|title=S.F.

===Temporary Transbay Terminal===
[[File:TransbayTemp.JPG|alt=Temporary Transbay Terminal|right|thumb|The Temporary Transbay Terminal]]
The '''Temporary Transbay Terminal''' was the San Francisco terminus for Transbay and regional buses for most of the 2010s. It was in operation from August 2010 through August 2018, when the new [[Salesforce Transit Center]] opened, and again from September 2018 to August 2019 during a temporary closure of the new center.  It occupied the city block bounded by Howard, Main, Folsom, and Beale Streets.

==== Closure & reopening ====
The Temporary Transbay Terminal initially ceased operations on August 12, 2018, with the opening of the new Salesforce Transit Center, only to be reopened weeks later, on September 25, 2018, following the discovery of support beam cracks at the Salesforce Transit Center.<ref>{{Cite news|url=https://abc7news.com/how-to-get-around-during-sf-salesforce-transit-centers-temporary-closure/4338690/|title=How to get around during Salesforce Transit Center's temporary closure in San Francisco|date=2018-09-25|work=San Francisco Chronicle|access-date=2018-09-25|language=en-US}}</ref> By December 5, 2018, [[Clipper card]] kiosks were reinstalled at the temporary terminal due to the continued closure of the Transit Center.<ref>{{cite news |last1=Matier & Ross |title=No date to fix SF transit terminal as Clipper kiosks return to temporary site |url=https://www.sfchronicle.com/bayarea/matier-ross/article/No-date-to-fix-SF-transit-terminal-as-Clipper-13443141.php |accessdate=8 December 2018 |agency=San Francisco Chronicle |date=5 December 2018}}</ref>
In April 2019, repairs were finished and it was determined that the cause of the cracking was partly caused when crews welding the beams together skipped a crucial step in the process required by the building code that led to tiny, micro-cracks forming. Multiple inspections failed to notice the skipped step, and those micro-cracks grew into larger ones. After a thorough set of repairs and reviews, the transit center reopened to the public on August 11, 2019, nearly one year after its closure.<ref>{{Cite web|url=https://www.sfchronicle.com/bayarea/article/Buses-using-SF-s-Transbay-transit-center-for-14296869.php|title=Buses roll again at SF's Transbay transit center, declared safe after nearly a year - SFChronicle.com|date=2019-08-12|website=www.sfchronicle.com|language=en-US|access-date=2019-08-15}}</ref>

==== Future development ====
In 2018, real estate developers submitted proposals to demolish the Temporary Terminal and replace it with [[affordable housing]] and a park, but with the permanent transit center still closed for repairs at that time, the future of that proposed project was not known.
