SAN DIEGO – A woman attempting to cross lanes on Interstate 5 while walking with a bicycle was killed in a crash Tuesday morning, authorities said.

The incident began around 9:30 a.m. when authorities were called to southbound I-5 near Clairemont Drive after reports that a white Honda Accord had gotten into a collision with the woman, according to a California Highway Patrol incident log. The deceased person’s identity was not immediately released.

Several southbound lanes of traffic were closed off by CHP for at least two-and-a-half hours for authorities to investigate the scene. Caltrans tweeted all lanes have reopened.

A toxicology report is pending through the San Diego County Medical Examiner’s office to see whether the victim was under the influence of alcohol and/or drugs.
