SAN DIEGO — The southbound Interstate 805 ramp to westbound Interstate 8 was closed for several hours Wednesday morning due to police activity after a man was found dead inside a vehicle.

Around 7:05 a.m., a Freeway Service Patrol employee spotted a silver Chevrolet on the right shoulder of the southbound I-805 transition ramp to westbound I-8, according California Highway Patrol Public Information Officer Jesse Matias.

The worker discovered that an unconscious man was sitting in the vehicle and requested CHP and an ambulance to the scene.

The man was pronounced dead at the scene, prompting an hours-long closure of the freeway ramp as authorities investigated.

A SigAlert was issued around 7:50 a.m. due to the police activity, closing the transition ramp and causing heavy traffic in the surrounding area. At approximately 10:11 a.m., Caltrans announced that the ramp and all lanes had been reopened.

The circumstances that led to the mans death are still under investigation and his identity has not yet been publicly released.
