Route description[edit]

Iowa Highway 14 begins in Corydon at Iowa Highway 2. It goes north past Millerton and intersects U.S. Highway 34 in Chariton. After leaving Chariton going north, it turns northeast near Williamson, then turns north shortly before intersecting Iowa Highway 5 and Iowa Highway 92 at Knoxville. It continues north past the locally famous "Mile Long Bridge", which carries the highway across Lake Red Rock, and then intersects Iowa Highway 163 in Monroe. It proceeds north to Newton, where it intersects Interstate 80 and a short overlap with U.S. Highway 6 begins. The overlap ends as it skirts the eastern edge of Lambs Grove. It continues north, then turns east and turns north again when it intersects Iowa Highway 224. It continues north through Laurel, then intersects U.S. Highway 30 at the southern edge of Marshalltown.

Iowa 14 then goes through Marshalltown and then intersects Iowa Highway 330 and Iowa Highway 96 before intersecting Iowa Highway 175 west of Grundy Center. Iowa 14 and Iowa 175 then overlap into Grundy Center. Iowa 14 turns north at Grundy Center and intersects U.S. Highway 20 before meeting Iowa Highway 57 near Parkersburg. They overlap through Parkersburg, then Iowa 14 turns north. It continues north until Iowa Highway 3, with which it overlaps for one mile (1.6 km) near Allison. It continues north west of Allison through Greene, goes through Roseville, then turns east towards Charles City. West of Charles City, it intersects U.S. Highway 18, U.S. Highway 218, and Iowa Highway 27, the Iowa designation for the Avenue of the Saints. It continues east into downtown Charles City and ends at another intersection with U.S. Highway 18.


Iowa Highway 14 was established July 1, 1920, when the Iowa highway system was established. On May 1, 2006, Iowa 14 was extended further into Charles City to intersect U.S. 18, which was rerouted around Charles City that day.
