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Subsection 34 of this rule is being repealed.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 This rule is being repealed because the South Dakota Department of Transportation transferred this segment of roadway to Pennington County.
Subsection 35 of this rule is also being repealed.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 This rule is being repealed because the South Dakota Department of Transportation transferred this segment of roadway to Pennington County.

70:01:02:21 - Custer County Speed Zone Rule
|
70:01:02:21 – Custer County speed zone rule. The current administrative rule sets the speed limit on State Trunk Highway 87 and U.S. Highway 385 in Wind Cave National Park at 45 miles per hour, except for a 0.8 mile segment of U.S. Highway 385 where the speed limit is 25 miles per hour. Under the proposed rule change, the 25 mile per hour speed zone on U.S. Highway 385 would be eliminated, resulting in a 45 mile per hour speed zone on all of U.S. Highway 385 within the boundaries of the Wind Cave National Park. At one time, U.S. Highway 385 was located along the visitor center at Wind Cave National Park, which justified lowering the speed limit to 25 miles per hour on the 0.8 mile segment near the visitor center. U.S. Highway 385 has been realigned, so the highway no longer passes in front of the visitor center. Because of this realignment, the 25 mile per hour speed zone is no longer necessary. The proposed rule change would also reduce the speed limit on State Trunk Highway 87 within the boundaries of Wind Cave National Park from 45 miles per hour to 35 miles per hour. State Trunk Highway 87 is a winding two-lane scenic road through a national park. Given these characteristics, reducing the speed limit to 35 miles per hour will enhance traffic safety.

70:01:02:45 - Meade County speed zone rule
|
70:01:02:49 – Meade County speed zone rule. Currently, subsection (13) of this rule establishes a 55 per hour speed zone on a segment of State Trunk Highway 79 from the north Pennington County line north to Interstate highway 90 at Exit 51 in Meade County. When Exit 51 was eliminated and replaced with Exit 52, part of this segment of State Trunk Highway 79 was renamed State Highway Maintenance Route 231 and part of the segment was removed from the state trunk highway system. As part of the Exit 52 construction project, a new segment of State Highway Maintenance Route 231 was also built. Under the proposed rule change, the speed limit on State Highway Maintenance Route 231, beginning at the north Pennington County line and proceeding north 1.05 mile to Peaceful Pines Road, would be 55 miles per hour. The speed limit on State Highway Maintenance Route 231 would then decrease to 45 miles per hour a distance of 0.6 mile east to Norman Avenue. These changes are being made to reflect the changes in the roadway designation and the changes to the roadway network due to the construction of Exit 52 and the removal of Exit 51.
Another proposed change to this rule would decrease the speed limit from 55 miles per hour to 45 miles per hour on the Interstate Highway 90 Service Road on the west side of Interstate Highway 90 beginning at Exit 40, then southeasterly to Exit 44 in Meade County. This change is the result of the realignment of this service road. The reduction in the speed limit will enhance safety and is supported by the results of a speed study.
