No towns meet the strict criteria for “Nebraska – South Dakota Bordering Towns” as defined here — there are no incorporated places that sit directly on or straddle the Nebraska–South Dakota state line under the inclusion rules used for this list.
Define the list strictly up front. Require a town to be officially inside one state and directly adjacent to the other state line, or to legally span both states. Under that rule, no entries appear. Settlements in this region tend to sit a short distance from the surveyed state line, or they are unincorporated places and farmsteads that do not qualify as towns for this list. Use this definition to avoid guessing or listing places that only come close to the border.
Understand the practical reasons for the empty result. State lines here follow survey lines and geography set long before towns formed. Many communities grew near county seats, rail stops, or river crossings rather than exactly on the border. Legal incorporation places a town wholly in one state. For reliable near matches, consult GNIS, U.S. Census data, and state DOT or county maps to find towns a few miles from the line, unincorporated communities near the line, or highway crossings that serve border traffic.
Explore related lists instead. Useful alternatives include “Towns within X miles of the Nebraska–South Dakota border,” county-by-county border town lists, unincorporated communities near the line, and major road crossings and ports of entry. Those categories give practical, scannable results for travelers, local researchers, and genealogists who need places near the state line.
