A Long Beach man will be arrested Friday after a fatal accident shut down a section of Interstate 5 north of San Diego overnight, officials said.
California Highway Patrol officers closed the northbound lanes of I-5 near the Lomas Santa Fe exit after the crash happened around 2 a.m.
The driver was in the slow lane, lost control and drove up an embankment, CHP officers said. At that time, the vehicle flipped onto its roof, killing the passenger.
The passenger was identified as a 41-year-old man from Delaware.
The driver suffered major injuries officials said as they transported him to Scripps La Jolla Hospital.
At one point, three lanes of the 5-North near Lomas Santa Fe were closed for officers to complete their investigation.
While there were no witnesses to the cause of the accident, CHP officers said the driver was under the influence at the time of the crash. They anticipate that he will be facing charges as a result.
