Traffic on Highway 260 east of Christopher Creek was backed up for hours Wednesday morning as emergency crews cleared the roadway of wreckage from a head-on collision between a snowplow and semi-trailer truck that sent one of the drivers to the hospital.
The injured man, Mark P. Murro III of Chandler, was admitted to Scottsdale Healthcare Hospital with two broken legs and a head injury.
The accident happened at 7:40 a.m. when the semi-trailer truck Murro was driving crossed the center line and ran headlong into an on-coming snowplow.
"We don't know yet why he crossed the center line," Department of Public Safety Officer Tony McDaniel said. "We haven't been able to determine if he fell asleep or he was reaching for something. The roads were damp, but there wasn't any ice. Witnesses said he was 'just there.'"
Harry Tomerlin of Payson, the driver of the snowplow, suffered only bumps and bruises.
The front ends of both vehicles were extensively damaged.
No charges have been filed, McDaniel said. Officers are still investigating the accident.
