Officials with the Transbay Joint Power Authority said Fremont Street won't open until next Wednesday, Oct. 17.
Work on a shoring system at the Salesforce Transit Center at Fremont Street between Howard and Mission streets continues and will continue into early next week, moving the scheduled reopening date of the one block closure.
"Work on the street level at Fremont Street is complete. Due to the complexity of the four-level designed shoring system, the work is continuing through the weekend and early next week on the bus deck and in the two levels of the train box," the TJPA said.
“It is important that we have an extremely robust shoring system to ensure that all levels of the transit center are safe and secure. Unfortunately, this requires us to keep the street closed until this work is complete. We will reopen Fremont Street as soon as safely possible and apologize for the ongoing impact to the public,” said Mark Zabaneh, executive director of the Transbay Joint Powers Authority.
Updates from TJPA:
First Street: Street level work on First Street is complete for this week. There will be one more night time closure (between 9 p.m. and 5 a.m.) next week, date to be determined. The street has a similar design as Fremont Street, and is also receiving a shoring system and will ultimately be permanently reinforced.
The cracked beams were found on Sept. 25 running parallel along the roof of the bus deck that goes over Fremont Street between Mission and Howard streets, prompting TJPA officials to abruptly close the transit center as well as the part of Fremont Street underneath the bus deck.
Engineers have inspected other areas of the transit center where the beams are configured similarly and haven't found any other problems.
The $2.2 billion transit center opened in August and served as a regional bus depot, with future plans to connect it to Caltrain and the state's high-speed rail line.
Buses are now operating from the Temporary Transbay Terminal at Howard and Main streets in San Francisco, where they operated from before the transit center opened.
