Pennington County began highway adoptions in 1990.  The Adopt-A-Highway Program provides an opportunity for organizations, businesses and/or individuals to volunteer to pick up litter in the right-of-way of Pennington County roads and be recognized for their efforts.  There are currently 116.27 miles of county road adopted by 52 groups/individuals.  Any county road can be adopted with the approval of the Board of Commissioners; however, a list of available roads has been developed for those determined to be of high priority for adoption.  A map showing roads currently adopted as well as those available for adoption is also available. Further information on the program can be found in the Pennington County, South Dakota Adopt-A-Highway Program Policy or by contacting the Highway Department at 605-394-2166.
