The crash occurred at around 4:40 a.m. on the northbound 405 Freeway, near the 101 Freeway, according to California Highway Patrol.

The driver of the big-rig could not immediately be found, CHP reported. It's unclear if anyone was hurt.

The transition ramp from the northbound 405 Freeway to the southbound 101 Freeway was shut down. Several lanes of the northbound 405 Freeway were also closed. There was no estimate on when it would reopen.

Fuel had to be safely offloaded from the big-rig before it could be towed, CHP said. 

Sky2 showed traffic backed up for miles as of 10 a.m. Morning commuters were advised to avoid the area.

The cause of the crash was unknown.
