The 22nd Avenue corridor is one of the most important arterial routes in Brookings, serving as a main route for commuting and cross-town traffic with access to many of the area’s retail stores. Portions of the corridor need of rehabilitation, and the City of Brookings would like to provide adequate capacity for future traffic demands. 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, and evaluating potential utility needs and constructibility issues with the preliminary design concepts. The corridor design had to meet design standards for a 5-lane cross-section that also provides for pedestrian and bicycle travel through the corridor. Banner used drone technology to capture updated aerial photography, which helped streamline some aspects of the project to meet critical project deadlines. The aerial shots provided an accurate representation of physical features and were used to draw marked utilities in the corridor. They were 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.
