At around 9:30 p.m. last night, the CHP received calls reporting a male pedestrian on the northbound side of the freeway, near Oak Street.
With officers enroute, additional calls came in reporting that the man was struck by a southbound vehicle.
So far, investigators have determined that the man ran across the northbound lanes of I-880 to the southbound side where he was struck by a white Honda.
The driver of the Honda stopped and is co-operating with investigators; the pedestrian was pronounced dead at the scene.
Witnesses are asked to call the Oakland CHP office.
