ALAMEDA — A 65-year-old man was struck and killed by a truck on southbound Constitution Way in Alameda at about noon on Monday.

The victim was walking in a crosswalk and had almost reached the sidewalk when he was hit by the truck in the far right-hand lane on the opposite side of the street of the Marina Village Shopping Center, said Alameda police Lt. Ron Simmons.

Police were interviewing witnesses to try to determine whether the pedestrian or the truck driver had the green light when the accident occurred.

The victim’s name has not yet been released. Simmons said he is believed to have been an Alameda resident.

Alcohol or drugs do not appear to be a factor in the collision at this time, Simmons said.

Southbound Constitution Way between Marina Village and Atlantic Avenue was closed for several hours while police conducted their investigation. It reopened about 7 p.m.
