The mudslide was reported to the CHP at 10:34 p.m., and arriving officers found a mass of mud about 100 feet wide blocking the roadway, CHP Officer Peter Van Eckhardt said.
Although only the southbound lanes were initially affected, a Sig-alert was issued at 11:11 p.m. once officers determined that cars could not safely travel in either direction, Van Eckhardt said.
Caltrans crews arrived with a bulldozer to remove the mess and had the road cleared by 5:27 a.m., when the Sig-alert was cancelled.
