Photo Gallery | PHOTOS: Big rig accident blocks Hwy 99 near Manteca

MANTECA -- Highway 99 is closed in both directions near Manteca due to an accident involving a big rig.

According to CHP, the truck hit a car, then lost control and slammed into the overpass pillars at Louise Ave in Manteca. It then caught on fire.

A 34-year-old medical assistant aspiring to be a nurse was the first on scene.  She took care of the victim until medics arrived.

A hazmat fire crew has been called out to the scene.

CHP says they won't be able to reopen the highway until they are sure the bridge did not suffer any structural damage.

They could not say how long this would take.
