Highway 16 / Neck Yoke Intersection - South Dakota Department of Transportation

At the 16/Neck Yoke Road intersection near Reptile Gardens, the corridor study advisory team is considering a reduced-conflict intersection. That is an intersection at which drivers entering the highway from a side street are required to make a right turn, and then have the opportunity to make a U-turn farther away from the intersection. The other option is to install traffic signals at the 16/Neck Yoke intersection. Both options are predicted to substantially reduce accident frequency at the intersection. The reduced-conflict intersection would keep traffic flowing along Highway 16 without stopping, and it would cost up to an estimated $5.4 million to implement. A signalized intersection would require through traffic to stop on Highway 16 and would cost up to an estimated $5.7 million. As of November 15, 2022, this project is in the conceptual phase. Information regarding a design firm and the general contractor selection timeline has not been disclosed. Although a firm timeline for construction has not been determined, construction is not expected to start prior to 2025. *Project information, including timeline and contacts, has been obtained through public sources.
