A jack-knifed big rig slammed through a freeway divider and left pieces of concrete scattered on the 5 Freeway, leading to a road closure that slowed the Thursday morning drive near Griffith Park.
The southbound side of the freeway reopened at about 6:30 a.m. Northbound lanes reopened later Thursday morning.
The wreck, one of several early Thursday, was reported at 2:21 a.m. just north of Colorado Street. The big rig was northbound on the 5 Freeway when it crashed through the freeway divider.
Several other vehicles struck concrete debris that was scattered on the road.
"We saw big chunks of concrete flying everywhere," said Tristan Nillo, who was driving the southbound 5 Freeway.
Nillo's vehicle was one of several towed from the location. There were no reports of injuries.
