Lincoln Co Hwy 106 Corridor Study

Lincoln County Highway 106 (271st Street) is the future growth boundary between the City of Sioux Falls and the City of Harrisburg and is currently under the jurisdiction of Lincoln County. Cooperation, coordination, and communication of the long term vision of this corridor is essential to ensure this corridor is properly planned and developed. All three jurisdictions have determined the need to jointly work together with administrative assistance from the South Eastern Council of Governments to achieve a well-planned, efficient, and safe corridor for all modes of travel. This project is being funded through a grant from the Sioux Falls Metropolitan Planning Organization (MPO) using federal transportation planning (PL) funds.
