A cement truck rollover closed northbound State Route 51 for more than three hours on Tuesday.
Northbound traffic was forced off the highway at Cactus.
The Arizona Department of Safety said the truck blew a tire and the driver lost control, hitting two vehicles and then striking the median wall, removing a large chunk. The truck was full of cement at the time.
Debris from the crash also blocked two lanes of southbound SR 51. Those lanes were reopened about 2:50 p.m. The northbound lanes were reopened about 3:30 p.m.
Minor injuries were reported.
