Iowa Highway 182 (Iowa182) is a state highway in the northwestern corner of Iowa. It begins at U.S. Highway 18 (US18) in Inwood and ends at Iowa 9 southeast of Larchwood. The highway has been in the primary highway system since 1930, when it was known as Iowa 26. On January 1, 1969, Iowa26 and Iowa182 swapped designations.

Route description

Iowa Highway 182 begins at an intersection with US 18 and County RoadA42 (CRA42). At the intersection, eastbound US18 approaches from the west, eastbound US18 approaches from the south, and CRA42 approaches from the east. Iowa182 travels north through Inwood for and continues due north through the farmland of Lyon County for to an intersection with Iowa Highway 9. The intersection with Iowa9 is very similar to the intersection with US18; eastbound Iowa9 approaches from the north and westbound Iowa 9 approaches from the east.

History

Between 1930 and 1968, the highway now known as Iowa182 was called Iowa 26. This was the second instance of Iowa26. The first was designated in 1920 with the rest of the primary highway system. It was originally a spur route from Primary Road No. 19 (now US18) to Rock Valley. Iowa26 was extended north from Rock Valley back to US18 in 1929.

In 1930, US18 was rerouted in Lyon and Sioux counties. The new routing of US18 went through Rock Valley, thus eliminating the need for Iowa26, which had connected Rock Valley to US18. The Iowa26 designation was moved northwest. It replaced County Road S, which followed the same course Iowa182 now follows.

On January 1, 1969, the Iowa State Highway Commission, now known as the Iowa Department of Transportation, renumbered several state highwayss. The changes to the highway system fixed a number of issues: creating continuous route numbers across state lines, removing duplicate route numbers where they were unnecessary, and extending route numbers in some locations. In this case, the former Iowa182 in Allamakee County crossed into Minnesota and became Trunk Highway 26. The two routes' numbers were switched and have remained the same since then.
