A hazmat crew worked to clean up materials spilled by the truck on the northbound Interstate 880 ramp that connects to eastbound Interstate 80.
The fire started at 1 p.m. Friday on the on-ramp near the Emeryville Ikea and one lane of traffic reopened around 7:30 p.m.
Drivers passed by slowly. But CHP officials eventually shut down the on-ramp.
