One person has died after a semi-truck crashed and caught fire on Interstate 805 near Mission Valley early Tuesday, causing lane closures, the California Highway Patrol said.
The crash was reported around 6 a.m. after the semi-truck appeared to hit a crash cushion, a safety device used to stop resistance during an impact, at the I-805 and Interstate 8 split. A witness told CHP that the semi “exploded” after impact.
The California Highway Patrol said all lanes of I-805 will be closed until at least midday. At 7:15 a.m., the CHP said they opened the #1 lane for stopped traffic.
