Pursuant to legislation passed by the 1985 Minnesota Legislature, the Minnesota Department of Transportation (MnDOT) entered into an agreement with the Upper Minnesota Valley Regional Development Commission (UMVRDC) directing the UMVRDC to conduct a highway jurisdiction study for the five-county area of Region 6W including: Big Stone, Chippewa, Lac Qui Parle, Swift, and Yellow Medicine Counties. This study was undertaken based upon the "Regional Jurisdiction Guidelines" established by the Commissioner of Transportation in December, 1985.
