Hazmat crews are responding to a crash involving a pickup truck and a dump truck in Lakeside Tuesday evening, the California Highway Patrol says.
A Sig Alert has been issued for Wildcat Canyon Road at Willow Road just before 4 p.m. after a Ford F-150 and a dump truck collided.
The crash caused the dump truck to run into the right-side embankment.
It's unclear what kind of material was spilled, but the CHP is waiting for San Diego County road crews to investigate and clean it up before reopening to traffic.
Northbound lanes have been reopened, but the southbound lanes are still closed.
