A street in Pacific Heights remains closed Friday morning, after a 10-foot-deep sinkhole opened in the middle of the road.
CBS 5 reports that road crews were filling what they believed to be an "indentation" in the roadway on Sacramento Street between Baker and Lyon Streets at around 5 p.m. Thursday when "a 17-foot by 22-foot area" of the street "collapsed."
San Francisco Public Utilities Commission spokesperson Charles Sheehan tells KRON 4 that the hole is between seven and 10 feet deep.
No workers were injured during the initial collapse, CBS 5 reports, and "there is no immediate threat to the homes near the sinkhole" according to KRON 4.
While Sheehan was loath to speculate on the cause of the sinkhole, he did say that there appeared to be sewer main break at the same location, CBS 5 reports. (The cause of the break is similarly unknown.) Water and sewer service for the area "has not been affected."
According to KRON 4, both Department of Public Works and SFPUC crews were "on-scene throughout the night prepping for repairs and monitoring the sinkhole." This morning, they'll be doing a “condition assessment and repairs,” Sheehan says, during which they hope to determine the cause of the mess.
It's unclear when work to repair the sinkhole will conclude. Obviously, until then, Sacramento Street will remain closed between Lyon and Baker.
