Iowa Highway 58 begins at the intersection of U.S. Route 63, known locally as Sergeant Road, and Hudson Road on the southern edge of Hudson. Iowa 58 passes Hudson High School and turns to the northwest through town. North of Hudson, the highway straightens to the north again and travels to a partial cloverleaf interchange with U.S. Route 20. Iowa 58 turns east onto US 20 and shares the roadway for one mile. Iowa 58 leaves US 20 at exit 255 on the outskirts of Cedar Falls. From the opposite direction, Iowa Highway 27, the Avenue of the Saints highway, also exits US 20 and the two routes head north. For, Iowa 27 / Iowa 58 travel on a signal-controlled freeway. This is the only section of the Avenue of the Saints highway in Iowa that is controlled by traffic lights. North of Greenhill Road, the last signal-controlled intersection, Iowa 27 / Iowa 58 share a freeway. One mile north of the Greenhill Road intersection is an interchange with University Avenue. East of this interchange, University Avenue is designated as Iowa Highway 934, but it is never signed as such. Iowa 27 / Iowa 58 continue north for, crossing the Cedar River near George Wyth State Park, before Iowa 58 ends at a full interchange with U.S. Route 218 and Iowa Highway 57. The US 218 interchange is also the eastern end of Iowa 57. The Avenue of the Saints highway continues north with US 218 towards Waverly.
History
The original Primary Road 58 connected the Jefferson Highway, now U.S. Route 65 west of Eldora to the Red Ball Route, now U.S. Route 218, east of Dysart. Primary Road 58 followed what is now Iowa Highway 175 to U.S. Route 63 to Iowa Highway 8. In the 1926 Iowa highway renumbering, Iowa 58 was truncated so that its east end was at Iowa Highway 14, and sections were renumbered Iowa 90 and Iowa 8. In March 1932, Iowa 58 extended east to Iowa Highway 137, replacing Iowa 90. In August 1932, Iowa 58 was truncated wes to Grundy Center, as Iowa Highway 57 replaced the section west of Grundy Center. In 1935, Iowa 58 extended north towards Hudson. It headed along Hudson Road and ended at US 20 on the northern edge of Cedar Falls. As a result of the highway renumbering in 1969, Iowa 58 was truncated at US 63 in Hudson, and Iowa 175 replaced the section west of Hudson. In the 1980s, US 20 was rerouted onto a freeway south of Cedar Falls and Waterloo. By 1989, Iowa 58's north end had been truncated to the new freeway. In the early 1990s, the freeway which Iowa 58 now shares with Iowa 27 was constructed. By 1996, it had been extended and routed onto the new Avenue of the Saints freeway, giving it its current length. The Iowa 27 designation was extended over the entire Avenue of the Saints highway in 2001.
