Jack-Knifed Big Rig Closes Lanes on I-15 Near SR-56

Truck carrying cookie dough jackknifes and tips on I-15 early Monday

Commuters heading southbound out of Escondido on Interstate 15 were faced with serious delays early Monday after a big rig filled with cookie dough jackknifed near the State Route 56 interchange.

Traffic was backed up for miles after the crash around 5 a.m. Several hours later, traffic was still at a crawl from north of Escondido to the I-15/SR-56 interchange.

HOV lanes were not affected. Those lanes were opened to all traffic - not just carpool vehicles -  to help people get around the Sig Alert. CHP and Caltrans later opened an additional HOV lane to help relieve the congestion. 

The Carmel Mountain Road on-ramp to I-15 was opened before 7 a.m.

An alternate route would be heading south on Carmel Mountain Road but expect delays.

The driver of the truck was injured and was sent to a nearby hospital for treatment. No details were given on the extent of his injuries.

Three or four tow trucks were called to help right the large truck and clear the lanes.

CHP officers and firefighters were still on scene as of 8:30 a.m. There has been no estimated time given for the reopening of all lanes.

Hazmat crews were called to the crash scene but officials say there were no hazardous materials released in the crash.
