MALIBU—The Pacific Coast Highway in Malibu was shut down during the morning hours on Thursday, August 18 due to a collision, according to reports. The highway was not fully re-opened until four hours after the incident.

Around 6:30 a.m., a collision occurred south of Las Flores Canyon Road. The collision involved a pickup truck and a big rig that had been hauling a load of gravel. One person had been trapped in the pickup truck that had ended up underneath the big rig. Crews worked to get the trapped person out of the pickup truck and into safety, remove gravel from the roadway and tow away the damaged trailer.

After the collision, drivers were advised to use the canyon roads to travel around the Pacific Coast Highway closure. The California Highway Patrol kept drivers updated using their Twitter account.

“SIGALERT IN MALIBU: PCH SOUTH OF LAS FLORES CYN RD ALL LANES BLOCKED UNTIL FURTHER NOTICE DUE TO A TRAFFIC COLLISION- REF LASO LOST HILLS,” tweeted the CHP Thursday morning.

Around 9:15 a.m. one eastbound lane was re-opened while all other lanes remained closed. Around 10:00 a.m. all eastbound lanes were once again open while all westbound lanes remained closed. At 11 a.m., the CHP’s Twitter account alerted drivers that all lanes on the Pacific Coast Highway were once again open for travel.

Canyon News left a message with the West Valley CHP office for more information, but did not hear back before print.
