The 22nd Avenue corridor is one of the most important arterial routes in Brookings, SD, providing access to many of the area’s retail stores and serving as a main route for commuting and cross-town traffic. Portions of the corridor are in need of rehabilitation and the City desires to provide adequate capacity for future traffic demand. The City retained the Banner/HDR team to provide a preliminary design study of the corridor. The study included determining the existing and future traffic capacity of the corridor, developing preliminary design concepts for the corridor to meet design standards for a 5-lane cross-section that also provides for pedestrian and bicycle travel through the corridor and evaluating potential utility needs and constructibility issues with the preliminary design concepts. Banner used drone technology to produce updated aerial photography and meet tight project deadlines. This provided an accurate representation of physical features and was used to draw marked utilities in the corridor. It was also used to help identify property lines and potential right-of-way conflicts. The technology proved to be very beneficial as a major intersection (6th Street and 22nd Avenue) and the adjacent Brookings Health System had significant improvements during the construction season. All plan sheets incorporated the most recent geometric and site improvements to aid in decision-making.
