OAKLAND -- A man who police say staggered onto eastbound Interstate 580 died Wednesday morning when he was struck by a car on the freeway, the California Highway Patrol said.

Officers arrived at the scene just after 1:11 a.m., after receiving calls that a man was hit near the Edwards Avenue exit, CHP Officer Daniel Hill said. When police arrived, the man was down in the center median, and a Chrysler 300 was pulled over to the right shoulder, Hill said.

Paramedics provided emergency medical aid, but the man was pronounced dead at the scene. His identification was not released pending notification of family.

A woman who was driving the Chrysler told police the man was walking in the No. 3 lane toward the No. 1 lane and walked directly in the path of her vehicle, Hill said. The Chrysler was in the No. 2 lane when the man walked in front of it, Hill said.

The woman was cooperating with police, the CHP said. All lanes of eastbound I-580 EB were closed at Edwards Avenue for approximately 90 minutes while police investigated, Hill said. The lanes were opened for all traffic about 2:30 a.m.

The CHP is urging anyone who may have seen the collision to call the CHP's Oakland Area Office at 510-450-3821, or the CHP's nonemergency public access number at 1-800-835-5247.
