Iowa Highway 920 (Iowa 920) was the northern half of the section of Iowa 150 that was vacated when it was rerouted over Iowa 101. It began at the same intersection in Benton County west of Walker where Iowa 101 ended. Iowa 920 headed east towards Walker, where the highway skirted the edge of town by curving to the south. The route headed due south along Center Point Road for a few miles until it curved southwest and back to the southeast into Center Point. Through Center Point, the highway was known as Franklin Street. In the southern part of town, where Center Point Road turned south, Iowa 920 ended.
