Iowa 48 continues north for Шаблон:Convert, again crossing the East Nishnabotna, until its northern end at U.S. Highway 6 west of Lewis.[2]
History
Originally, Iowa Highway 48 was a short highway connecting Shenandoah and Red Oak, roughly along the path the route takes today.[4] By 1952, the route was in its present location and ended at US 6 west of Lewis. Only the original section had been paved at this time.[5] By 1976, the entire highway was paved.[6]
