Update 11:21 a.m. One lane of the  710 north is now open following a fatal crash early Saturday morning, according to Caltrans. The northbound Interstate 5 won't reopen until midnight.

Previously: The northbound 5 Freeway and the northbound 710 Freeway in the city of Commerce are closed after portions of a bridge widening project collapsed on top of a car early Saturday morning after it crashed into a concrete barrier. The driver was killed, and a passenger was taken to the hospital. 

The California Highway Patrol says the driver was heading north on the 5 Freeway, drove up onto the middle section between the 5 north and 710 north, then hit a concrete barrier around 2 a.m. that was supporting wood and steel beams. The beams fell and piled on top of the car. 

CHP Sergeant Jose Nunez says you should take an alternate route if you were planning to take the 5.

"Main ones I'd say approaching from Orange County would be the 5 to the 605 or the 91 to the 110 around the area," Nunez told NBC L.A. "As far as the closure up on the 710, the northbound lanes are being diverted onto the northbound 5."

The CHP says the 710 north could reopen today — but the 5 north will not be ready to reopen until at least Sunday.

Correction: A previous version of this story incorrectly implied that the bridge itself had collapsed. KPCC regrets the error.
