Traffic has been diverted in San Francisco's Inner Richmond District around the intersection of Lake Street and Second Avenue, after a section of the asphalt collapsed into a hole in the middle of the street.
Officer Carlos Manfredi of the SFPD said there are no reports of injuries or property damage, and there does not appear to be anything intentional involved.
Manfredi said the initial call came in just after 5 p.m., Monday afternoon, after a 15-foot-wide by 15-foot-deep hole was spotted in the middle of the intersection. It appears the hole opened up immediately after the weight of a vehicle cleared that section of the asphalt, possibly causing the collapse.
The asphalt surrounded a manhole cover but there is no clear indication what caused it to give way at this point, said Manfredi, and it is unknown if recent street work at that intersection led to the collapse.
He said city workers may be able to put steel plates over the hole, although it is likely that authorities will block the intersection throughout the night and into tomorrow for reasons of public safety.
