Highway 101 at Oyster Point in South San Francisco was closed for several hours in both directions Saturday due to major flooding, according to the California Highway Patrol.
Caltrans crews responded to the scene around 11 a.m. to work on clearing the water from the roadway. The CHP reopened northbound lanes around 8 p.m. and southbound lanes around 9 p.m.
Heavy rainfall and high tides were contributing to the lengthy delay in clearing the drains to get rid of the standing water, the CHP said.
The CHP urged motorists to avoid the area and advised using Interstate 280 as an alternate route.
