I-190 Corridor / Silver Street Interchange Study in Rapid City

blank space

Reason for Study:

Given the aging I-190 structures with low clearance at the Silver Street interchange in Rapid City, the South Dakota Department of Transportation has targeted the interchange for replacement. This study is to evaluate options for the future of the interchange, and possibly for the entire I-190 corridor.

Study Limits:

The study will examine the I-190 highway corridor and the influencing arterial and collector roadways. The primary route to be studied follows the I-190 corridor from SD44 (Omaha Street) to I-90, and includes all ramps and ramp intersections along the corridor, emphasizing the Silver Street interchange.

Public Meetings

The South Dakota Department of Transportation (SDDOT) has a long history of public involvement in the development of transportation plans and projects. The 2005 passage of the Safe, Accountable, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) requires a public involvement process. In accordance with the Department's public involvement plan document, the I-190 Corridor / Silver Street Study strives to keep the public involved with the study as much as possible. Public meetings for the study will occasionally be scheduled to collect public input, provide information and answer questions.
