70:01:02:01 - Minnehaha County speed zone rule
The proposed rule amendments will change speed limits on State Trunk Highway 115 north of Sioux Falls and on Highway 38 in and around Hartford in Minnehaha County. The proposed speed zone rule changes will also update highway references and eliminate speed limit provisions that are no longer needed because of highway jurisdictional transfers. The reasons for amending the speed zone rules are to enhance safety, add clarity, and repeal speed limits for highways that are not under the jurisdiction of the South Dakota Department of Transportation.
