(July 1, 1920-June 25, 1934)

WEST End: IA 4/12, now J46 at US 275/IA 2, Fremont County

Save for the extension into Riverton, 42 was unchanged for its sixty years. Because it remained on the 1981 map, I have a page on the main site for this route. (6/16/03)

EAST End: Riverton, Fremont County

The final end of IA 42 was J64/K Street at Summer Avenue. Riverton (1920 pop. 568, 2010 pop. 304) lost nearly half its people over a century.
