At West Amana, Iowa 220 turns east onto an east–west alignment. It moves through High Amana and turns to the south-southeast towards Middle Amana, where it passes the Amana Corporation manufacturing facility. From Middle Amana, it turns to the northeast and then to the east as it enters Amana, ending at a four-way stop with US 151.
History
Iowa 220 was created in the early 1930s as a spur route from West Amana to Amana.[3] By 1947, Iowa 220 ran from South Amana to Amana along the current extent of the route. However, the route continued east for 1.5 miles (2.4 km) where it ended at East Amana and south for 1 mile (1.6 km) to Upper South Amana.[4] At its longest, the route was 9.5 miles (15.3 km) long.[5] The western end of the route was pulled back to its current western end in 1976.[6] Four years later, its eastern end was truncated back to the intersection with Iowa 149 in Amana.[7] In 1985, Iowa 149 was replaced by US 151 between Cedar Rapids and Interstate 80.[8]
