Southbound Interstate 5 near Camp Pendleton turned into a virtual parking lot Friday morning after a multi-vehicle crash involving a propane tanker blocked all lanes of the freeway, authorities said.
The crash in northern San Diego County near the shuttered San Onofre nuclear reactor occurred around 7:10 a.m. on south I-5, just north of the scales, and quickly backed up traffic headed into San Diego County from Orange County, according to the California Highway Patrol.
Crews were busy cleaning less than 40 gallons of fluid that spilled across the freeway and truckloads of debris, the CHP reported on its website.
All lanes of traffic were closed until around 8:30 a.m., when one lane was reopened. Three of the four lanes had been opened as of shortly after 10:30 a.m., CHP officer Mike Martinez told KPCC, with an estimate that the highway would be fully reopened within another 15 minutes.
An injury report was not immediately released.
