Nobody was injured when a semi truck tipped over Monday afternoon on the new roundabout at Morris Street and Pioneer Road. Assistant police chief Steve Klein says the road was blocked for about two and a half hours in order for crews to unload the semi and upright the trailer. Klein says it appears the semi was southbound on Morris entering the roundabout and as it rounded the curve the load shifted in the trailer causing it to roll over on its side. Speed is a possible factor. The company, Conway Trucking, was cited for failure to secure a load.
