Iowa 62 begins at a T intersection with Iowa 64 on the east side of Maquoketa. To the northeast of the junction lie the Jackson County Fairgrounds. The highway curves to the northeast and it crosses the Maquoketa River. Near Andrew it intersects Iron Bridge Road which leads to Spragueville. The highway briefly turns to the northwest and enters Andrew, home of Iowa's first governor, Ansel Briggs. From there, the roads winds to the northeast towards Bellevue. Just west of Bellevue, the highway enters the southern edge of the Driftless Area, a geologically-distinct area of the upper Mississippi River valley characterized by high bluffs and deep valleys. Iowa 62 ends a few yards from the Mississippi River at an intersection with US 52 in downtown Bellevue.
History
On the first map of primary roads published by the Iowa State Highway Commission, Primary Road No. 62 was shown connecting No. 20 at Fulton to Bellevue. Within a couple years, the road was rerouted from Fulton to begin in Maquoketa. Aside from straightening the route in a few locations, the routing remains the same today as it did in the 1920s. In September 1925, a memorial plaque was installed in Andrew next to a tree purportedly planted by Ansel Briggs, the first governor of Iowa, who lived in the town during his term in office. Governor John Hammill suggested to the Ansel Briggs Memorial Association that they establish a memorial highway to honor Briggs. Local business leaders supported the idea immediately and even suggested Briggs's memory would be best honored by a paved road. By the end of the year, the Jackson CountyFarm Bureau also supported the memorial highway. In 1927, Jackson County voters approved a $1 million bond for the improvement of highways in the county; Iowa 62 was expected to be upgraded to a gravel road. The bond vote was not without controversy. A state senator, who opposed the bond, was charged with assault after allegedly slapping the face of the editor of the Maquoketa Excelsior after the newspaper published an unflattering story about the senator's opposition. The highway was graveled within two years. In 1956, a steel and concrete bridge over the Maquoketa River replaced an adjacent 80-year-old span. Paving work between Maquoketa and Andrew began in May 1959. A contract for paving the final of road between Andrew and Bellevue was let in 1960; work continued through the next year. The 1962 Iowa highway map showed the highway as fully paved.
