Iowa Highway 1 (Iowa 1) is a state highway in the U.S. state of Iowa that extends from Keosauqua to Anamosa. It travels nearly 120 miles (190 km), mainly through rich farmland and small communities. Iowa 1 provides an important link to Iowa City and the University of Iowa as it passes through campus. Portions of the route today date back to the late 1830s, when Martin Van Buren was president, making Iowa 1 one of the oldest routes in the state, pre-dating the current primary highway system by nearly eighty years. The highway was seriously damaged by the Cedar River in the Iowa flood of 2008, which closed the highway for seven weeks.
