Rapid City Area MPO Major Street Plan Update & Analysis

Our Changing Communities

Rapid City adopted a Major Street Plan in 1990 and has performed numerous revisions; however, many of the proposed future road alignments have not been analyzed since the initial creation of the plan. Many of the proposed improvements have become dated due to changes in land use, development, and construction projects through the years.

Additionally, most of the other RCAMPO member agencies have adopted Major Street Plans or Transportation Plans, leading to inconsistencies among road alignments and classifications.

Goals of the Major Street Plan Update

Issues with slope, constructability, and alignment have surfaced on numerous proposed roadway segments. A preliminary look at identifying alignment and constructability issues was completed in the RapidTRIP 2045 Metropolitan Transportation Plan.

This study is intended to expand on that process and update the Major Street Plan and develop conceptual alignments for selected corridors.

• Review current Major Street Plan for inconsistencies between RCAMPO jurisdictions
• Review topographical and alignment constraints
• Review growth areas and prioritize corridors for conceptual alignment development
• Develop conceptual alignments for priority corridors
• Engage the public
