RICHMOND--A crash between a big rig and a sedan near Richmond spilled fuel on the roadway and prompted a temporary closure of Interstate 80 near the Pinole Valley Road off-ramp Monday afternoon, according to the California Highway Patrol.

The crash occurred at 3 p.m. on westbound I-80, prompting all four lanes to be closed, said Sgt. Jeff Thomas. No injuries were reported, but the impact of the crash caused the big rig to leak fuel, spilling about 10 gallons onto the freeway.

A traffic alert was issued as officials closed the freeway as well as the Pinole Valley Road off-ramp and on-ramp. All but one lane were reopened by 3:45 p.m., Thomas said. The cause of the crash is still under investigation.
