state highway in Iowa, United States

Route description
Iowa Highway 28 begins at Iowa Highway 92 at Martensdale in Warren County. From Martensdale, it continues north through Prole and Norwalk before crossing into Polk County. Just across the county line, Iowa 28 meets Iowa Highway 5 at a partial-cloverleaf interchange. Just north of the interchange is Army Post Road, a former alignment of Iowa Highway 5. Iowa 28 crosses the Raccoon River just south of Railroad Avenue in West Des Moines. From the river to the Interstate 235 interchange, the east side of the street is 63rd Street in Des Moines, while the west side of the street is 1st Street in West Des Moines. The dual designation of street names is particularly confusing to drivers and residents alike.

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.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 22, 2025. The linked authority identifier is Q1415226. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
