Iowa Highway 60
state highway in Iowa, United States
Iowa Highway 60 (Iowa 60) is a north–south state highway in northwest Iowa. The highway runs at a southwest-to-northeast angle. The southern end of Iowa Highway 60 is near Le Mars at a freeway interchange with U.S. Highway 75 and U.S. Highway 75 Business. Its northern end is at the Minnesota border just south of Bigelow, Minnesota, where the highway continues in Minnesota as Minnesota State Highway 60.
The highway was designated on January 1, 1969, when it replaced Iowa 33. It was renumbered to provide a continuous number across the state line into Minnesota. Since 2004, the highway has been upgraded to expressway status, with some freeway sections, as part of a highway corridor connecting Sioux City with the Twin Cities metropolitan area in Minnesota.

Why this record matters
The phrase “state highway in Iowa, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
