An 18-wheeler carrying a load of pipes rolled on U.S. Highway 93 south of Wikieup on Monday morning.
A medical helicopter was called in to take one person for treatment, an Arizona Highway of Public Safety spokesman said.
The truck rolled near milepost 146 south of Interstate 40 about 6:05 a.m., the spokesman said.
One lane was blocked by the pipe, but traffic was moving around the collision, the spokesman said.
There was no estimate as to when the blocked lane would be cleared, the spokesman said.
No other information was immediately available.
