An overturned gravel truck closed all but one of the southbound lanes of traffic on Interstate-5 just south of state Route 52 on Monday morning.
The truck spilled thousands of pounds of gravel across the freeway, according to reports from the California Highway Patrol, just after 9 a.m. The gravel was piled 2-inches thick for nearly 75 yards, police said.
The accident happened after a tire on the semi truck blew, causing the truck to roll over into the fast lane and through the center divide, the highway patrol reports.
The overturned truck also spilled diesel fuel onto the freeway. Special equipment was brought in to clean the gravel and fuel spill.
The gravel spill took crews more than four hours to clean up.
