A stretch of Pacific Coast Highway in Pacific Palisades reopened Tuesday night after "burning and dangling" power lines covered lanes of traffic.
The problem was reported near Sunset Boulevard about 10:20 a.m., Brian Humphrey of the Los Angeles Fire Department said.
The Los Angeles Department of Water and Power sent "multiple crews" to the scene to repair the lines, according to Kim Hughes of the LADWP.

Rain possibly caused an insulator to fail, which sparked an electrical fire at the top of the pole, LADWP officials said.
Hughes said electrical service to 417 customers was interrupted but resumed by Tuesday night.
PCH was closed between Topanga Canyon Boulevard and Temescal Canyon Road while crews worked to handle the problem, Humphrey said. Lanes reopened before 5:30 p.m., CHP officials said.
The closure created concern among parents of students who live in Santa Monica but attend Malibu High School. The school's principal notified parents this afternoon that two bus loads of students would be allowed through the closure area by the California Highway Patrol, but the students would still be arriving home late due to the traffic congestion in the area.
A 9-mile section of coastal route is closed in Ventura County, where a mud and rock slide covered the road on Sunday between Yerba Buena and Las Posas roads.
