An overturned big rig in San Dimas has shut down several lanes on the 210 Freeway.
A SigAlert was issued about 2:20 a.m. for the east and west 210 Freeway after a portion of the truck blocked lanes on both sides of the road, according to the California Highway Patrol.
At 1:42 a.m., the driver of the big rig lost control and collided with the concrete divider near North San Dimas Avenue, according to the CHP. The big rig burst into flames and overturned, blocking all lanes.
During the crash, the big rig also took out a sign on a large pole that went across all freeway lanes.
