Iowa Highway 412
From Wikipedia, the free encyclopedia
Iowa Highway 412 (Iowa 412) was a state highway in Waterloo, Iowa. It began at U.S. Highway 63 (US 63) in southwestern Waterloo and traveled to the east and northeast approximately four and three-quarters miles (7.6 km) to US 218 in southeastern Waterloo. The route served as a southern bypass of Waterloo. The highway was added to the primary highway system in 1960 and given to the City of Waterloo in 1983. It was replaced in function by US 20, which that year relocated onto a freeway less than one-half mile (800 m) south of San Marnan Drive.
