About the Project

The project is for the construction of a new single point interchange at Exit 1 of Interstate 190 in Rapid City, South Dakota. Construction activities include erection of a new bridge and demolition of the old bridge and completion of an interchange for access directly from I-190 to and from North Street, Silver Street and Philadelphia Street. Pedestrian and bicycle access will be improved by installing a bike path along the western side of the interstate to the north, as well as a sidewalk along 11th street with connection to the Rapid City bike path. Utilities upgrades include storm sewer, sanitary sewer and water lines.
