The slide was reported at 1 a.m. and blocked two lanes south of Spencer Avenue, said CHP officer Peter Van Eckhardt.

Caltrans cleared the debris and reopened both lanes at 5 a.m., he said.

No vehicular accidents or roadway damage were reported and the cleanup did not affect the holiday morning commute to San Francisco.
