San Francisco police on Tuesday responded to an oil spill in the SoMa district, where a motorcyclist spilled on the slick roads.

Avout 12:15 p.m., the fire department tweeted that hazardous materials units were at the scene, stretching about four blocks from Howard Street to South Van Ness Avenue.

The city sent out an automated Everbridge AlertSF to subscribers just before 2 p.m. saying the spill was cleared and that streets were reopened to traffic. 

It wasn't immediately clear what kind of oil it was.
