Traffic remained slow through the area late this morning. "There's a significant residual backup that will take time to dissipate," CHP Officer Sam Morgan said.
The accident happened just before 8:30 a.m. near Broadway when the driver lost control of the truck.
The crash left the front of the big-rig atop a four-foot high cement wall, hanging over the edge of the elevated highway, Morgan said.
"The driver was able to safely exit the cab of the truck," Morgan said. "He is still at the scene being interviewed by our traffic investigators."
The big-rig's diesel tanks were punctured in the crash and about 100 gallons of fuel spilled on the highway and a parking lot below. Oakland fire and California Department of Transportation crews responded to clean the spill, Morgan said.
Big-rig tow trucks managed to pull the truck back up onto the highway, and the two left lanes reopened at 10:26 a.m. The remaining lane opened at 11:12 a.m.
