Fire crews responded to a fully engulfed camper trailer Thursday afternoon on Maricopa-Casa Grande Highway about one mile east of White and Parker Road.
The roadside blaze closed portions of the highway in both directions for more than an hour. The Maricopa Police Department re-opened the road at approximately 3:40 p.m.
The cause of the fire is still unknown, said MPD Patrol Officer Jeff Brooks.
The camper trailer was reportedly being hauled east toward Casa Grande. Maricopa Fire/Medical Department and Ak-Chin Fire Department responded to the scene.
