SAN DIEGO -- A gasoline tanker truck crashed and overturned on a freeway on-ramp near Qualcomm Stadium Tuesday, causing a fuel spill and shutting down a stretch of Friars Road, authorities said.

The non-injury accident occurred about 5:40 p.m., as the driver of the rig was trying to enter northbound Interstate 15, according to the San Diego Fire-Rescue Department and California Highway Patrol.

Emergency crews shut down the connector road along with a stretch of Friars Road and other ramps leading to and from the freeway, the CHP reported.

Firefighters set up barriers to dam the spilled fuel and called in a hazardous-materials crew to supervise clean-up operations, a dispatcher said.
