WICKENBURG, Ariz. (AP) - Authorities say two drivers, including one of a UPS semi-truck, are dead after their vehicles crashed head-on just north of Wickenburg.
Arizona Department of Public Safety spokesman Bart Graves says the collision happened around 5:15 a.m. Tuesday on US-93.
He says the preliminary investigation indicates a semi-truck heading south crossed the center median for an unknown reason.
The semi collided with a UPS semi-truck traveling in the northbound lane.
Both drivers were pronounced dead at the scene.
Authorities say US-93, which connects Phoenix and Las Vegas, will be closed for several hours as investigators review the scene.
