The road forms a north-south route through the west of the state, from the Missouri border at Shenandoah through the regional towns of Harlan and Cherokee to the Minnesota border at Allendorf. The route has relatively little through importance, as the road does not connect major cities and Interstate 29 is a relatively short distance away. The road is 350 kilometers long.
US 59 in Missouri comes from St. Joseph. While US 59 runs parallel to I-29 in Missouri, it is further from I-29 in Iowa. In the south of Iowa, US 59 runs about 35 kilometers from I-29, in the north this has increased to almost 100 kilometers. US 59 is a somewhat secondary route due to the fact that there are no larger towns on the route. US 59 is almost completely single-lane, only in a few places there are short sections with 2×2 lanes. US 59 crosses several east-west routes that are often more important than US 59 itself. The main connection is on Interstate 80 at Avoca. Also of interest are short double numberings with US 18 and US 20. US 59 continues through flat terrain, mostly made up of meadows. US 59 does not cross any major river in Iowa.
