An overturned big rig hauling crushed vehicles overturned on southbound Highway 101 in Novato early Friday morning, initially blocking all lanes in the morning commute direction, according to the California Highway Patrol.
As of about 7:45 a.m., the two far right lanes in each direction of the freeway had reopened, the CHP said.
The crash occurred at about 1:20 a.m. on Highway 101 near De Long Avenue after the truck driver fell asleep and veered into the center median, causing the rig to roll over, the CHP said.
Debris was spread over both sides of the freeway, and one oncoming motorist hit some of the debris.

Southbound traffic was being diverted off at De Long as crews tried to get the rig upright. Some traffic was able to bypass the crash scene on the freeway shoulder, the CHP said.
The CHP did not indicate an estimated time for when the blocked lanes would reopen.
