Statewide Transportation Improvement Program – STIP
The STIP is a four-year program listing projects developed through the coordinated efforts of the Department of Transportation, Transportation Commission, state and federal agencies, local and tribal governments, metropolitan planning organizations, public agencies, transportation providers, citizens and other interested parties. The program identifies highway and intermodal improvements to preserve, renovate, and enhance South Dakota's transportation system.
The 2025-2028 STIP has been approved by the South Dakota Transportation Commission, the FHWA and FTA.
The 2025-2028 STIP Interactive Map depicts the location and type of improvement for the Department's major highway projects.
