Two people injured, transported to hospital, after a four-vehicle crash on northbound I-15 in San Diego.

Freeway traffic was snarled in the Inland Corridor Wednesday when an SUV involved in a four-vehicle crash came to rest on its top in the middle of Interstate 15, authorities said.

The crash on northbound I-15 just north of Bernardo Center Drive was reported at 7:34 a.m., according to the California Highway Patrol.

Three lanes of traffic were blocked due to the collision, Caltrans reported.

Paramedics took two patients from the crash scene to a hospital, a San Diego fire-rescue dispatcher said, adding both were taken to Palomar Medical Center West in Escondido.
