The transit center was abruptly ordered closed on September 25, 2018, following the discovery of a crack in a steel beam supporting the rooftop park. A crack in a second beam was found the next day. Repairs to these beams were completed in May 2019, while construction and road closures related to building issues were still ongoing. The rooftop park reopened on July 1; bus service that uses the surface level resumed on July 13. Full bus service resumed at the transit center on August 11, 2019.
Design
Designed by Pelli Clarke Pelli Architects (PCPA), the Salesforce Transit Center is about long and wide. It occupies the entire block between Minna and Natoma Streets (just southeast of Mission Street), and stretches from Beale Street to 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 rooftop park.
The bus deck has a dedicated highway ramp (consisting, in part, of a

Construction
The first phase of construction consisted of the aboveground bus terminal, including retail spaces and the rooftop park, plus the concrete shell of the underground rail levels. It cost $2.4 billion, of which $500 million was for the underground shell. On August 7, 2010, all bus service was moved to the interim Temporary Transbay Terminal. The $18 million outdoor terminal is located on the block bounded by Folsom, Beale, Howard and Main Streets in the South of Market district, two blocks from the site of the former Transbay Terminal. Ground was broken for the new Transbay Transit Center four days later. Much of the initial construction work was underground, and aboveground evidence of construction did not appear until late 2014. As originally planned, the Transit Center was anticipated to be complete by late 2016, with bus operations expected to commence by August 2017.
Demolition of the former Transbay Terminal and ramps was completed in September 2011.

The first phase of the new Transit Center was originally to be completed by the end of 2017. This was delayed to March 2018 in July 2017, and to June 2018 that December. On December 26, 2017, Muni began operating route buses into the ground level of the terminal in order to meet the federal deadline of some service to the terminal beginning in 2017. On June 16, 2018, Muni began operating all , , , , and buses to the surface level of the terminal.

service moved from the Temporary Transbay Terminal three days later on August 15, leaving Amtrak Thruway as the sole remaining bus operator using the Temporary Transbay Terminal. Amtrak buses began using a street-level stop at Salesforce Plaza on Mission Street near Fremont Street on October 28, 2019. That stop was temporarily relocated along Mission Street to near 2nd Street on November 9, 2020.
Without the revenue from the 100,000 expected rail passengers, the bus-only terminal is expected to lose as much as $20 million annually.
Extended closure
The transit center was abruptly ordered closed on September 25, 2018—six weeks after opening and during Salesforce's annual Dreamforce conference—following the discovery by workers installing the final ceiling panels of a “major crack” in a steel beam supporting the bus deck above Fremont Street. Beale, Fremont, and First Streets were closed beneath and adjacent to the transit center; Beale and First reopened soon after. The Temporary Transbay Terminal, which had been in use during construction of the new transit center, was hastily reopened to serve riders.

s or ''weld termination holes'' cut into the beams, that were added after the shop designs were submitted for approval. Weld access holes have more stringent building code requirements than weld termination holes, and it was not clear which type of holes were added. In February 2019, the TJPA announced that it expected repairs to be completed in June 2019, but cautioned that the center would not reopen until the MTC peer review panel published its final report. In April 2019, it was determined that the cracks were caused when crews welding the beams together skipped a crucial step—mandated 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.

The TJPA announced on May 10 that repairs were complete. The rooftop park reopened on July 1, 2019. Muni and Golden Gate Transit buses resumed using the surface bus plaza on July 13, and the full facility reopened on August 11.
Other issues and criticism
The park has been criticized for allowing a commercial company to own the naming rights, as well as not having enough bike lanes connecting to other major transit routes.''Wired'' criticized the park for its control over access, claiming that there could never be a political demonstration at the park.
In September 2018, just a month after the transit center's opening, the TJPA revealed that the walkway around the rooftop park, made of decomposed granite, had begun to deteriorate much faster than expected. Repairs on the pathway were completed in May 2019, but it is not clear if the costs fall under warranty.
New skyscrapers
Along with the new transit center, thirteen towers have been built or proposed on adjacent parcels, ranging from to tall, on land freed by the demolition of the former terminal and bus and freeway ramps. The most prominent of these is the city's new tallest building, Salesforce Tower. Two of the skyscrapers, Salesforce Tower and 181 Fremont, are linked directly to the rooftop park. Salesforce Tower has a dedicated pair of elevators, open to the public and accessible via the rear lobby, which serve as one of the access points to the park.

Future rail service
The Transbay Transit Center project was designed to include a tunnel (the Downtown Rail Extension or DTX) 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. The Caltrain extension depends on the electrification of its rolling stock, as the current diesel engines are not appropriate for tunnel service. When this project is completed, Caltrain riders would no longer need to transfer to Muni to reach the downtown financial district.
