70:01:02:07 -- Yankton County speed zone rule; 70:01:02:52 -- Moody County speed zone rule.

The South Dakota Transportation Commission is considering amendments to the following rules: 70:01:02:07 - Yankton County speed zone rule; and 70:01:02:52 -- Moody County speed zone rule. The effect of the rule amendments will be to: (1) increase the speed limit on U.S. Highway 81 over the Missouri River in Yankton County and designate the ending point of this speed zone at the South Dakota/Nebraska border; and (2) modify the speed limits on State Trunk Highway 34 in and around Colman, South Dakota. The reasons for adopting the proposed amendments are to enhance safety and make the rules clearer.
