Iowa Highway 46
State highway in Iowa, United States
Iowa Highway 46 (Iowa 46) was a state highway in Polk County, Iowa. It began at an intersection with Iowa 5 near Avon. It traveled north and west through the industrial section of southeastern Des Moines. It ended at Iowa 163, also known as E. University Avenue, in Des Moines next to the Iowa State Fairgrounds.
The route was created in 1953 when a section of Iowa 60 was rerouted through Des Moines. Maintenance of the highway was turned over to local jurisdictions in 1998, after a new, controlled-access bypass carrying US 65 opened nearby and after the bridge over the Des Moines River was removed. Minimum speed limits were removed from the bypass after the Iowa 46 bridge closed because of a lack of river crossings for farm implements.
