Officers were called at 11 p.m. Thursday to an accident involving a pedestrian on East Grant Road near North Mountain Avenue.
Tucson Fire personnel were rendering aid to the pedestrian, but he was pronounced dead at the scene.
Detectives learned that the man was crossing the eastbound lanes of traffic on Grant when he was struck by a 2012 Dodge Challenger that was eastbound in the center lane.
The pedestrian was not crossing in a crosswalk, police said.
Detectives determined that the driver of the car was impaired, police said.
Byron Omar Calderon, 36, was arrested and booked into the Pima County jail on one count of manslaughter. Police said speed was not a factor in the crash.
The pedestrian's name has not been released.
There have been 26-traffic related deaths in Tucson this year, including seven pedestrians, police said. That's compared to 25 deaths this time last year.
