No towns meet the criteria for “South Dakota – Iowa Bordering Towns”
Note that no incorporated places sit on or straddle the South Dakota–Iowa state line. In other words, there are no towns that officially belong to both South Dakota and Iowa or whose municipal boundary runs along that state line.
Define “bordering” as a single town that directly touches both states. The South Dakota–Iowa border runs along rivers and rural land. Settlements historically form on one side or the other. State law and municipal incorporation usually keep towns inside a single state. That makes a list of true “South Dakota – Iowa Bordering Towns” empty.
Technical and historical maps show many towns near the line but on one side only. A common near match is the Sioux City tri‑state area — Sioux City, Iowa; South Sioux City, Nebraska; and North Sioux City, South Dakota — where towns sit very close across rivers and bridges but do not share a single municipal boundary. Other nearby South Dakota places, like Dakota Dunes (SD), sit close to the Iowa line and make useful points of comparison for travelers and researchers.
Explore related categories instead. Look for towns within a short distance of the SD–IA line, river crossing points and highway bridges, or tri‑state metro areas (for example, the Sioux City region). These will give the practical, travel, and mapping information users expect when searching for “South Dakota – Iowa Bordering Towns.”
