• 70:01:02:36 – Hughes County speed zone rule;
• 70:01:02:58 – Stanley County speed zone rule;
• 70:03:01:65. Longer combination vehicle -- Approved routes and access restrictions

The South Dakota Department of Transportation is proposing changes to speed limit rules for highways under the department’s jurisdiction in Hughes County and Stanley County. Effective July 1, 2025, certain highways under the jurisdiction of the department in Hughes County will be re-named, so the speed zone rule for Hughes County is being revised to reflect these name changes. The posted speed limits on the re-named highways, however, will remain the same. Additionally, speed zone rules are being repealed for roads in Hughes County and Stanley County that are under the jurisdiction of the U.S. Army Corps of Engineers, the South Dakota Department of Game, Fish and Parks, and local governments, because those entities establish their own speed limits. Finally, the speed zone rules for U.S. Highway 14 over the Missouri River Bridge are being amended to accurately reflect the statutory boundary line between Hughes County and Stanley County.
The department is also proposing changes to the administrative rule that establishes state trunk highway routes for longer combination vehicles. The changes to this rule are the result of the re-naming of certain highways in Hughes County effective July 1, 2025. The rules are being amended to reflect these highway name changes, but the actual routes established for longer combination vehicles are not changing.
The purpose of the rule changes is to update highway segment names, repeal speed zone rules that are no longer needed for roads controlled by other entities, and correctly reference the statutory boundary line between Hughes and Stanley Counties on U.S. Highway 14 over the Missouri River Bridge.
