A semitrailer truck carrying boxes of cheese caught fire Friday and crashed on a freeway in the northern San Fernando Valley.
The southbound 5 Freeway in Sun Valley was closed for the cargo and fuel spill cleanup. Engineers also are checking for damage on a freeway overpass.
The big rig struck a guardrail at about 4 a.m. near the 5 Freeway Penrose Street exit. The flames were doused in less than 30 minutes, but fuel and boxes of cheese spilled on the freeway, according to California Highway Patrol.
