UPDATE (9:54 AM): The California Highway Patrol said two big rigs crashed Monday morning on southbound I-5, south of Twissleman Road, and both drivers were killed. That area of southbound I-5 is still closed.
CHP said a preliminary investigation found that a 2014 Freightliner traveling on northbound I-5, for an unknown reason, crossed the dirt center median and hit a 2009 Kenworth head-on.
The crash caused both vehicles and their cargo to spill out onto southbound lanes of I-5 and partially into the No. 1 northbound lane, said CHP.
The northbound No. 1 lane of I-5 was close temporarily but has since reopened.
The cause of the crash is still under investigation.
A Caltrans says a deadly crash Monday morning closed I-5 south of the Kings/Kern County line.
As of 7 a.m. Monday morning, all lanes of southbound I-5 near Twisselman Road are closed and Caltrans advises drivers to seek an alternate route.
There is not current ETA for when southbound lanes will reopen.
According to Caltrans, a big rig overturned and is blocking all lanes of southbound traffic.
Northbound lanes are open, according to the California Highway Patrol.
