SAN DIEGO (KGTV) - A tanker truck overturned on an Otay Mesa street Monday, sending thousands of gallons of cooking oil and water onto the roadway.
The crash was reported shortly before 8:40 a.m. on Coronado Avenue, just before the on-ramp to northbound Interstate 5, according to the California Highway Patrol.
According to authorities, the product the tanker was carrying somehow caused the vehicle to lose its balance and overturn. A fire official at the scene told 10News that the result was a spill of about 6,500 gallons of cooking oil and water from the truck’s tank.
The crash and spill forced the closure of the ramp to northbound I-5 and a stretch of westbound Coronado Avenue leading to the onramp.
The fire official said the spill is not a fire hazard and is more of an environmental concern, as much of the liquid entered a storm drain.
10News learned the driver was not hurt in the crash. No other injuries were reported.
Authorities expect the clean-up process to last into the early afternoon.
