SD Highway 115 Corridor Study

About

The South Dakota Department of Transportation (SDDOT) has initiated a study of S.D. Highway 115 between East Dike Place/Drive in Sioux Falls, S.D., and West 4th Street in Dell Rapids, S.D. The SDDOT pavement management system indicates a future need for pavement replacement or reconstruction on this corridor. This vital 15-mile stretch of highway, connecting the communities of Dell Rapids, Baltic, Renner, and Sioux Falls, has experienced increasing volumes of traffic which presents an ongoing effort and challenge to plan for the sustainability of Highway 115.

This study is a collaborative effort between SDDOT, Federal Highway Administration (FHWA), Sioux Falls Metropolitan Planning Organization (MPO)/South Eastern Council of Governments (SECOG), City of Sioux Falls, City of Baltic, City of Dell Rapids, Minnehaha County, stakeholders, and the public to develop a comprehensive plan for the corridor. This study will serve as a long-range plan for the SDDOT and other agencies for future improvements to address needs along the corridor.
