A jackknifed big rig on the southbound lanes of Interstate 5 in Newhall snarled traffic, prompting a SigAlert in the area with traffic estimated to be blocked for an hour.
California Highway Patrol officers responded to reports of the incident around 9:30 a.m. on Interstate 5, near Lyons Avenue, and backed up traffic to at least McBean Parkway, according to the alert.
“It was reported as a red, big rig across lanes and is blocking the No. 3 and 4 lanes,” said CHP Officer Peter Nicholson. “They can’t move it without a tow truck.”
The trailer was reported as empty. There was no report of injuries, he added.
