state highway when the system was created in 1920. It extended from Primary Road No. 2 and No. 20 in Muscatine north to No. 61 between Anamosa and Wyoming. When the U.S. Highway System was created in 1926, the terminal roads of Iowa 38 were renumbered to Iowa 22 at Muscatine and Iowa 117 in Jones County. Throughout the 1930s, the highway was extended several times. Firstly, in 1932, it was extended over Iowa 117 for a couple miles and then north as a stub route to Center Junction. Three years later, it was again extended north to U.S. Highway 151 in Monticello. Finally on May 11, 1938, it absorbed all of Iowa 113, which had connected Monticello to Iowa 10 near Edgewood.
