70:01:02:02. Pennington County speed zone rule.

70:01:02:02 – Pennington County speed zone rule. Subsection 13 and 17 of this rule are being amended to replace the reference to State Trunk Highway 79 with State Highway Maintenance Route 231. These changes are being made to reflect the renaming of these segments of State Trunk Highway 79 to State Highway Maintenance Route 231. Subsection 28 of this rule currently sets speed zones for a 0.59 mile stretch of the Interstate Highway 90 crossover road located at interstate milepost 78.39 in Pennington County. Under the current rule, the speed limit on this crossover road is 25 miles per hour beginning 0.45 miles south of the south ramp terminal and proceeding north 0.08 mile, then the speed limit increases to 45 miles per hour for a distance of 0.32 mile north, and then the speed limit decreases to 40 miles per hour for a distance of 0.19 mile north. This subsection is being amended to set a speed limit for only a 0.16 mile segment of the Interstate Highway 90 crossover road. Under the proposed rule, the speed limit would be 45 miles per hour on the Interstate Highway 90 crossover road at Exit 78 (New Underwood Road) beginning 0.07 mile south of the centerline of Interstate Highway 90, then north 0.16 mile. This change is being made due to Pennington County accepting jurisdiction over the Interstate 90 crossover road except for the 0.16 mile segment that is addressed in the proposed rule. Subsection 34 of this rule is being repealed. Subsection 34 set the speed limit on Interstate Highway 90 Maintenance Route 230 westbound in Box Elder beginning 0.6 mile east of the junction with Interstate Highway 90 Maintenance Route 435 at Exit 66 of Interstate Highway 90 (Ellsworth Air Force Base – Box Elder interchange), then west to the junction with Interstate Highway 90 Maintenance Route 435, then west for 0.5 mile to the intersection with Ellsworth Air Force Base Commercial Gate Road, then west to the junction with Interstate Highway 90 at Exit 63. This rule is being repealed because the South Dakota Department of Transportation transferred this segment of roadway to Pennington County. Subsection 35 of this rule is also being repealed. Subsection 35 set the speed limit on Interstate Highway 90 Maintenance Route 230 eastbound in Box Elder beginning at the junction of Interstate Highway 90 at Exit 63, then east to a point 0.6 mile east of the junction of Interstate Highway 90 Maintenance Route 435. This rule is being repealed because the South Dakota Department of Transportation transferred this segment of roadway to Pennington County.
