Iowa Highway 25 (Iowa 25) is a north–south highway in the southwest and west-central portion of the state. It begins at Iowa 2 seven miles (11 km) south of Clearfield. It heads north along a two-lane road through Creston, Greenfield, and Guthrie Center on its way to its northern end at U.S. Route 30 (US 30) near Scranton.

Iowa 25 was created in 1926 as a replacement for Primary Road No. 16, which was redesignated further east. It originally connected US 30 to US 34 in Creston. In the early 1930s, it was extended south to Blockton by absorbing all of Iowa 184. By the end of the 1930s, the highway reached the Missouri state line, where it ended for over 40 years. In the late 1970s and early 1980s, the highway south of Iowa 2 was turned over to local jurisdictions.

Route description

Iowa 25 begins at a

T intersection with Iowa 2 along the Taylor–Ringgold county line south of Clearfield. Eastbound Iowa 2 comes from the south along the county line and turns east into Ringgold County while Iowa 25 heads north from the intersection along the county line. It passes through Clearfield, which lies in Taylor County, and continues north towards the quadripoint of Taylor, Adams, Union, and Ringgold counties (counter-clockwise from the southwest).[3]

North of the quadripoint, Iowa 25 runs along the Adams–Union county line. It crosses the

U.S. Highway 34 (US 34) and the two routes head east together towards Creston. Shortly after crossing into Union County, the two routes turn to the northeast. In southern Creston, the two routes split with US 34 continuing to the east and Iowa 25 heading north along Sumner Street through the western part of town. Near Southwestern Community College, the route turns to the west along Townline Road.[4] It crosses Summit Lake, a reservoir created by damming the Platte River. West of Summit Lake, the highway turns 90 degrees to the north and passes close to Green Valley State Park.[3]

Iowa 25 crosses into

US 6 at a diamond interchange adjacent to a golf course.[6]

Iowa 25 south of Guthrie Center

North of the interchange, Iowa 25 enters

Middle Raccoon River. Further north, between the communities of Bayard and Bagley, Iowa 25 intersects Iowa 141. The two routes head west towards Bayard and split on the eastern side of town.[3]

North of Bayard, Iowa 25 crosses into

US 30. North of US 30, the roadway becomes County Road N65 (CR N65), which carries the Lincoln Highway Heritage Byway.[3]

History

The original Primary Road No. 25 was designated with the rest of the

Primary Road No. 16 in 1926.[2] When the Adel–to–Winterset route changed numbers in 1926, it was not paved at all, but the segment in Madison County was graded, the first step in becoming a paved road.[10]

The second iteration of Iowa 25 was created in 1925 during the time when the

U.S. Highway System on the state's primary road network. In order to avoid driver confusion, the commission reorganized various route numbers to simplify the system and to remove any duplicated numbers, i.e. US 30 and Primary Road No. 30. Iowa 25 was allocated along a section of former Primary Road No. 16 from Scranton to Creston. Iowa 16 was rerouted to the east, absorbing all of the previous incarnation of Primary Road No. 25.[2]

A few years later, the highway commission created Iowa 184, which ran from US 34 south to Blockton.[11] In early 1933, Iowa 25 was extended southward along US 34 and absorbed all of Iowa 184.[12] In 1938, it was extended an additional four miles (6.4 km) to the Missouri state line. Iowa 357 was created as a short spur route into Blockton.[13]

Iowa 25 stayed largely the same for over 40 years. By 1980, it was truncated at County Road J55 (formerly Iowa 357) near Blockton.[14] Two years later, it trimmed back to its northern junction with Iowa 2, where it remains today.[15]
