Iowa Highway 1 is a state highway that runs from south to north in eastern Iowa. The highway traverses 120.32 miles (193.64 km) across Iowa, beginning south of Keosauqua. It connects the cities of Fairfield, Washington, Iowa City, and Mount Vernon before ending at an interchange southwest of Anamosa at US 151. Iowa 1 is one of the oldest routes in the state; portions of the route date back to the late-1830s.


Route description

Iowa Highway 1 begins at Iowa Highway 2 south of Keosauqua. Iowa 1 crosses the Des Moines River in Keosauqua, before turning north. North of Keosauqua and south of Birmingham, Iowa 1 and Iowa Highway 16 overlap for 2.21 miles (3.56 km). At Fairfield, Iowa 1 intersects U.S. Route 34 at a new interchange, and, for one block, overlaps the former alignment of US 34, now U.S. Route 34 Business, officially Iowa Highway 904.[2] Near Richland, Iowa 1 becomes east–west and overlaps Iowa Highway 78 for 7.61 miles (12.25 km) before turning north at Brighton. North of Brighton, Iowa 1 crosses the Skunk River and continues north to Washington. Iowa 1 and Iowa Highway 92 skirt the western edge of Washington and continue north for just over 3 miles (4.8 km). At Kalona, Iowa 1 intersects Iowa Highway 22.

Iowa Highway 1 enters the Iowa City area from the southwest and intersects U.S. Route 218 / Iowa Highway 27, the Avenue of the Saints. Along Riverside Drive, Iowa 1 overlaps U.S. Route 6 for 34 miles (1.2 km) before crossing the Iowa River in downtown Iowa City. On Burlington Street, Iowa 1 passes the University of Iowa library, the old state capitol, and the Ped Mall. Iowa 1 turns north onto Governor Street (northbound) and Dodge Street (southbound). The one-way streets rejoin as Dodge Street before intersecting Interstate 80. Iowa 1 continues north through Solon, then turns northeast to go through Mount Vernon, where it intersects U.S. Highway 30. It continues on a northeasterly alignment through Martelle, then ends at a freeway interchange southwest of Anamosa with U.S. Highway 151.


Primary Road 1 was originally part of the Jefferson Highway, a north–south route extending in Iowa from Lamoni to Northwood, Iowa.[3] It was designated on 1 July 1920, but was replaced by U.S. Route 65 and U.S. Route 69 in 1926.

The current Iowa Highway 1 was designated in 1926, extending from Iowa Highway 3 near Keosauqua to Iowa Highway 38 near Rochester.[4] In 1962, Iowa 1 was realigned north of Iowa City along Iowa Highway 261.[5] The section of Iowa 1 from Iowa City to Iowa 38, a part of the Herbert Hoover Highway, became Iowa Highway 979.[3] Although no segments were paved at designation, the entire route was paved by 1969.

The former Iowa 261 segment of Highway 1, from Anamosa to Iowa City, approximately follows part of the route of the territorial and military road from Dubuque to Iowa City. This road, authorized by President Martin Van Buren in 1839, was known as Dillon's Furrow, named after the Dubuque merchant Lyman Dillon who surveyed the route and marked it with a furrow.[6] Most of the deviations of the route of Highway 1 from Dillon's original route are the result of road straightening or bypasses around town centers.

In 1997, it was announced that parts of U.S. Route 151 and Iowa 1 would become the first Super 2 highways in Iowa.[7] A 42-mile (68 km) section between Washington and U.S. Route 30 was likely to be improved in 2002, but because of funding shortages, the project was scratched.

In the Iowa flood of 2008 Iowa 1 was heavily damaged south of Mount Vernon by flood waters of the Cedar River, necessitating the closure of the highway between Mount Vernon and Solon. Repairs of the damaged section began on July 11th and were completed by July 30th.[8]
