Iowa Highway 37

File:Dunlap, IA.jpg

Iowa Highway 37 begins at an intersection with Iowa 175 east of Turin and adjacent to Iowa 175's crossing of the Maple River. The first {{convert|1+1/2|mi|spell=in}} of the route are part of the Loess Hills Scenic Byway.{{cite map|publisher=Iowa Department of Transportation|title=Transportation Map|url=http://www.iowadot.gov/maps/msp/pdf/current/stmapmain.pdf|year=2010|accessdate=December 4, 2010}} The highway travels east and then southeast through the Loess Hills, a region of dunes east of the Missouri River created by wind-deposited silt from the Missouri River valley. At Soldier, Iowa 37 exits the Loess Hills and meets Iowa 183. From Soldier, the highway travels {{convert|13|mi}} to the southeast to Dunlap. In Dunlap, Iowa 37 overlaps US 30 for {{convert|1/4|mi|m|spell=in}}. Eastbound Iowa 37 overlaps westbound US 30; this phenomenon is known as a wrong-way concurrency. Between Dunlap and Earling, Iowa 37 travels in a stairstep path to the south and east for {{convert|13|mi}}. At Earling, the highway intersects the northern end of Iowa 191. Its last section is {{convert|4|mi|spell=in}} long, connecting Earling to US 59.

Originally, Iowa Highway 37 began at US 75 in Onawa to US 59 east of Earling. The westernmost {{convert|8|mi|spell=in}} of the route were overlapped by Iowa 175. In 1966, Iowa 37 was truncated to its current western end near the Maple River.{{cite map|publisher=Iowa State Highway Commission|url=http://www.iowadot.gov/maps/msp/historical/pdf/1967_front.pdf|title=Iowa State Highway Map|year=1967|accessdate=December 4, 2010}} In 1971, a new section of US 59 was opened {{convert|1|mi|spell=in}} to the west of the former alignment. As a result, Iowa 37 was extended {{convert|1|mi|spell=in}} north and {{convert|6|mi|spell=in}} east to Irwin, absorbing Iowa 268{{cite map|publisher=Iowa State Highway Commission|url=http://www.iowadot.gov/maps/msp/historical/pdf/1972_front.pdf|title=Iowa State Highway Map|year=1972|accessdate=December 4, 2010}} The section from US 59 to Irwin was short-lived. In 1980, the section east of US 59 was turned over to Shelby County.{{cite map|publisher=Iowa Department of Transportation|url=http://www.iowadot.gov/maps/msp/historical/pdf/1981_front.pdf|title=Iowa State Highway Map|year=1981|accessdate=December 4, 2010}}
