SAN FRANCISCO (KRON) — Friday morning workers are beginning to replace a broken sewer main that caused a sinkhole collapse in San Francisco’s Yerba Buena neighborhood on Tuesday.
Contractors hired by the agency began the work early Friday morning to replace a 3-by-5-foot brick sewer main that broke after around 140 years of use and lead to a sinkhole that formed on Tuesday around 5:30 p.m., right in the midst of the commute rush hour.
The 12-by-5-foot sinkhole, which is 9 feet deep, appeared on Mission Street between New Montgomery and Second streets, SFPUC officials said.
No one was injured when the sinkhole formed, although the front end of a vehicle got caught in it when the sinkhole initially opened up, SFPUC officials said. The vehicle later had to be pulled out.
Sewer service has not been affected and water service is similarly unaffected, according to SFPUC officials.
SFPUC officials expect that the work to replace the sewer main, which is believed to have broken in part due to its age, to be completed on Saturday around noon.
A block on Mission Street, between New Montgomery and Second streets, will be closed throughout the work.
Some San Francisco Municipal Transportation Agency buses will have to be rerouted.
