Crews then worked all Friday and into early this morning to pour concrete and repair the roadway.
While the roadway is back open, crews will again temporarily close it sometime this coming week to do final paving work, SFPUC officials said.
SFPUC officials however did not say which day or for how long the roadway would be closed.
The cause of the main break was likely due to the age of the pipe, which was built in 1985, according to SFPUC officials.

The break resulted in some flooding to the Moscone Center Garage and about 200 customers in the area initially had their water shut off, SFPUC officials said.
