Major injury crash at Oil Well Hill — one lane of 101 closed (updated 8:36pm)

UPDATE 8:36 p.m. — The road is now open to one way traffic control.

UPDATE 8:02 p.m. — Some more information coming. The crash appears to have involved at least two cars and a potentially a big rig. Multiple people have been airlifted away from the scene. A call has gone out for CalTrans to assist in a major oil clean up, and the cars will need to be towed. At this time it appears that the road is closed, but even after one-way traffic control begins, expect major delays.
