Two lanes of the eastbound 60 Freeway reopened in Hacienda Heights Tuesday morning after Monday evening's big rig crash.
Closures remain in effect more than eight hours after two eastbound big rigs collided. One rig overturned and the other caught fire underneath the Azusa Avenue overpass.
Caltrans engineers examined whether the truck cab fire just after 8 p.m. Monday compromised the integrity of the overpass, for motorists on the bridge and for those on the 60 freeway below, authorities said.

As of 5:30 a.m. Tuesday, two eastbound lanes of the 60 were open and the rest remained closed, according to the California Highway Patrol. All westbound lanes of the freeway were opened earlier Tuesday
The collision occurred shortly after 8 p.m. at Azusa Avenue, said CHP Officer Monica Posada. Neither driver was injured, according to county fire officials.
Firefighters used foam to coat road surfaces and metal surfaces, to reduce the chance of sparks igniting anything combustible during the cleanup. A primary concern was whether the truck cab fire seriously damaged the Azusa Avenue overpass.
One truck was carrying dog food and the other was carrying tires, which were being offloaded.
