An empty milk tractor-tanker and a vehicle crash on northbound I-5 in the Castaic area of Los Angeles. No injuries reported.

A crash between an empty milk tanker truck and a vehicle shut down multiple northbound lanes on the 5 Freeway in the Castaic area early Wednesday morning.

The collision occurred shortly before 5 a.m. north of Lake Hughes Road. The crash resulted in an oil spill.

All northbound lanes were initially shut down, but California Highway Patrol officials reopened one lane at about 5:30 a.m. The other lanes remained closed as crews worked to clean the roadway. At one point, northbound traffic was backed up to Hasley Canyon Road.

All lanes have since reopened.
