Interstate 40 has reopened west of Flagstaff in northern Arizona after a five-hour closure Wednesday morning because of a fatal accident and smoke in the area.
The highway was closed between Flagstaff and Williams.
The Department of Public Safety says one person was killed in a three-vehicle wreck involving two trucks and a passenger vehicle.
DPS spokesman Bart Graves says there were numerous wrecks with minor injuries in the area due to reduced visibility from smoke from a prescribed burn that it's too early to say whether the smoke caused the fatal crash.
