UPDATE (January 6, 2017): Highway 178 was reopened Friday evening, according to Cal Trans. Highway 155 has also been reopened.

========================================

Both Highway 155 and Highway 178 remain closed Friday morning after weather slammed Kern County Thursday.

Mud and rock slides along both highways caused the closures.

The California Highway Patrol initial reported that 155 had reopened overnight, but have since said that it is closed.

CalTrans is working to clear rocks and boulders in the road.

There's no timetable for either to reopen.
