Riley County commissioners on Monday unanimously approved lowering the speed limit on three roads in Ogden following a traffic study. The roads are currently posted at 30 mph, the maximum speed allowed by state law for residential urban areas. McMillan recommended a 20 mph speed limit, citing the gravel road surface, reduced stopping distances, dust and the residential character of the area. Commissioners approved the 20 mph speed limit unanimously. The post Riley County lowers speed limit on roads near Ogden appeared first on News Radio KMAN.
