A cement truck owned by Perez Brothers overturned Saturday morning just before the entrance into Maina.
According to authorities, all vehicles were diverted through Nimitz Hill road as an unexploded ordnance was discovered near Piti Basketball Court.
Shortly thereafter, the driver of the cement truck lost control of the big rig resulting in it flipping on its side.
Witnesses at the scene said the driver of the rig was taken to Naval Hospital for treatment.
Perez Brothers staff could be seen at the scene mitigating spills from the truck.
Traffic has been diverted through Maina and Snake Road until the scene has been cleared.
