The tree was reported down at Cuesta Cala Road in Topanga around 10:30 a.m. Thursday, the California Highway Patrol reported.
A SigAlert was issued, and it took a couple of hours to clear the downed tree.
The Los Angeles County Fire Department responded to the location, but did not take anyone to a hospital, a spokeswoman for the department said.
