Route descriptionEdit

Iowa 81 begins at the Missouri border, where it is a continuation of Missouri Route 81. The highway heads in a northeasterly direction from that point, passing by Indian Lake Park along the way. It ends at Iowa 2 on the west side of Farmington.[3]


Prior to its current designation, Iowa 81 was known as Iowa 114. On January 1, 1969, Iowa 114 and Iowa 81 traded route numbers in order to harmonize route numbers with neighboring states, Route 81 in Missouri, in this case.[1] At the time of its designation, the highway was a fully paved road.[4]
