Access Class Definitions
Interstate – the designated Interstate highway system, including I-90, I-29, I-229, and I-190.
Expressway – high-speed divided highways serving interstate and regional travel needs.
Free Flow Urban – higher speed facilities with access subordinate to through traffic movement.
Intermediate Urban – serves through traffic while allowing moderate access density.
Urban Developed – traffic artery with high access density. Access and through movement have equal priority.
Urban Fringe – rural highway serving developing area immediately adjacent to a city or town. Access regulated to provide future through-traffic priority.
Rural – low volume, high-speed facility. Access points are spaced for safety and operations efficiency.
70:09:02:01. Access-location criteria. The highway classifications and access location criteria displayed in the table in Appendix A, South Dakota Access-Location Criteria, shall be used to determine whether or not an access permit is granted, and if granted, the location of the access. The department shall determine the access classification for each highway using Appendix A. An engineering study of sight distance, corner clearance, operational efficiency, safety and adjacent land use may also be conducted by department personnel prior to granting access and may alter the criteria shown in the table. A traffic impact study, if required, shall be conducted pursuant to § 70:09:01:07. Coordinated access planning, when conducted under § 70:09:02:03, shall supercede any determination may be applying Appendix A. The department may choose to adopt and defer to local criteria on any state highway facility located within the local jurisdiction if the access location criteria promulgated by the local unit of government are more stringent than those contained in Appendix A. The criteria in Appendix A do not apply if the department has acquired access rights through gift, purchase, or condemnation.

70:09:02:02. Variance from access-location criteria. The area engineer may grant a variance from the access-location criteria in § 70:09:02:01. The granting of the variance shall be in harmony with the purpose and intent of this chapter. No variance may be considered until other feasible options for meeting access-location criteria are explored. Any applicant for a variance from these criteria shall provide proof of unique or special conditions that make strict application of the provisions impractical. This shall include proof that:
(1) Reasonably convenient access cannot otherwise be obtained;
(2) No feasible engineering or construction solutions can be applied to mitigate the condition; and
(3) No alternative access is available from a street other than the primary roadway.
No variance may be granted, unless a strict application of access-location criteria would deny reasonably convenient access or would endanger public health, welfare, and safety. A variance from local access-location criteria must be granted by the local jurisdiction prior to the department's consideration of the variance if the department has deferred to more stringent local criteria. This section does not apply if the department has acquired access rights through gift, purchase, or condemnation.

70:09:02:03. Access planning. Any access point on a state highway in or adjacent to an urban area may be determined by access planning. The department or any unit of local government may initiate an access plan. A local government shall obtain the participation of the department on any access plan that includes a state highway. Any access plan shall be in harmony with the purpose and intent of this chapter. Any plan jointly developed by a local agency and the department shall be approved by the local entity and the department prior to taking effect. If a local jurisdiction declines to participate in access planning, the department may complete an access plan primarily considering the safety and efficiency of the highway system. Nothing in any access plan prepared solely by the department shall be deemed to interfere with any local land use planning and zoning authority. The original approving agency must ratify any amendment to an approved access plan.
