Route description

Iowa Highway 127 in Mondamin

Iowa Highway 127 begins at an interchange with Interstate 29 (I-29) west of Mondamin, traveling east along a two-lane highway. Just east of I-29, it meets Harrison County Road K45 (CR K45), which is a former alignment of US 75. Three miles (4.8 km) east of Mondamin, it meets the southern end of Iowa Highway 183, which is part of the Loess Hills Scenic Byway (LHSB). The LHSB follows Iowa 127 for 1+1⁄2 miles (2.4 km) before Iowa 127 turns to the east and the LHSB continues south along CR L20. The route travels east for 6 miles (9.7 km),[2] passing through Magnolia, after which it turns to the south towards Logan. The designation ends at US 30 in downtown Logan.[3]

In 1968, upon completion of I-29 west of Mondamin, US 75 was relocated onto I-29 and Iowa 127 was extended west to the interstate.[4]
