Iowa Highway 48 is a 48-mile-long (77 km) state highway which runs from north to south in southwest Iowa. It begins at the northern edge of Shenandoah at U.S. Route 59 and ends at U.S. Route 6 near Lewis. The highway has seen few changes since its creation.
Iowa Highway 48 begins in Shenandoah at an intersection with U.S. Route 59 (US 59), which serves as the line separating Fremont County and Page County. It heads east for one mile (1.6 km) before turning to the northeast to become parallel to a line of the BNSF Railway. It travels northeast for 6 miles (9.7 km) and turns east shortly after passing through Essex. Three miles (4.8 km) east of Essex, Iowa 48 turns north at an intersection with Page County Road J20 (CR J20).
From CR J20, Iowa 48 heads due north for 12 1⁄2 miles (20.1 km) to the intersection with US 34 in Red Oak. From Red Oak, Iowa 48 continues due north for 8 miles (13 km) until it turns east to cross the East Nishnabotna River and pass through Elliott before turning back to the north. It then travels north for 6 miles to Griswold, where it intersects Iowa 92. Iowa 48 continues north for 5 1⁄2 miles (8.9 km), again crossing the East Nishnabotna, until its northern end at U.S. Route 6 west of Lewis.
