LOS ANGELES (CBSLA) — All lanes of the southbound 710 Freeway were shut down at the 5 in East Los Angeles for hours Thursday after a tanker truck overturned and spilled antifreeze into lanes.

The crash was first reported at about 1:45 a.m., just north of the 5 Freeway, according to the California Highway Patrol. A Sigalert for an unknown duration was issued when antifreeze or fuel was found to be leaking from the truck.

Traffic was diverted onto the southbound 5 Freeway as crews worked to get the truck back upright and clean up the spill.

Two southbound lanes were reopened, but the others were expected to remain closed until at least noon.
