NB 5 reopening after long closure in Castaic from hazmat spill

CASTAIC, Calif. -- Holiday traffic was at a standstill for hours and backed up for miles on the northbound 5 Freeway in the Castaic area after a truck spilled hazardous materials in lanes.

The SigAlert was finally lifted around 6 p.m., some three hours after the closure. It was expected to take some time before traffic would clear.

The CHP initially shut down all lanes northbound in the Castaic area after the spill, reported just after 3 p.m.
