Lanes on Pacific Coast Highway in Malibu reopen after water main break Traffic lanes in both directions on Pacific Coast Highway have been reopened in Malibu after crews worked to repair a water main break, authorities said late Thursday. The break occurred near Pacific Coast Highway and Trancas Canyon Road about 7 p.m. and briefly caused a full closure of the thoroughfare, said Lt. John Lecrivain of the Los Angeles County Sheriff's Department's Malibu/Lost Hills Station. Water sprayed across both lanes of PCH, and a sinkhole formed on one side of the highway. The water flow was stopped at about 9:20 p.m., and crews were assessing the damage and cleaning roadways late Thursday. Cones were placed around the sinkhole, and traffic lanes were opened in both directions shortly before 11 p.m., sheriff's officials said. Broad Beach Road, which was closed because of water running downhill onto the road, was also reopened hours later, according to the Los Angeles County Sheriff's Department. Drivers should expect delays throughout the night, Lecrivain said.
