Golden Spike Road Improvements Project
Benton CSAH 3 (Golden Spike Road) Highway 10 to CSAH 1 (Mayhew Lake Road)
Project Purpose and Need
Benton County and the City of Sauk Rapids are developing a preliminary design for CSAH 3 (Golden Spike Road) from the west exit ramp of Trunk Highway 10, to the intersection of CSAH 1 (Mayhew Lake Road). Improvements are needed to serve existing and future traffic demands anticipated to be generated by private development in the corridor. Previously completed feasibility studies concluded that long term needs can be most cost effectively accommodated by providing modern roundabouts at major intersections. The "multiple roundabout" solution was found to have distinct safety and capacity benefits compared to conventional intersection designs at an overall project cost savings of approximately $10 million. The costs savings is possible because the overall roadway width for the roundabout solution is less than what would be needed for conventional designs with traffic signals and turn lanes. The existing CSAH 3 bridge over Highway 10 will be utilized with the roundabout plan but would need to be replaced to accommodate turn lanes if a conventional signalized solution were to be pursued. Roundabouts are being planned for CSAH 3 intersections with Highway 10 west exit ramp; the east exit ramp (includes CSAH 57 (Quarry Road); 10th Avenue/Industrial Boulevard; and, CSAH 1 (Mayhew Lake Road). Completing the preliminary design phase for the project will set the stage to have the project ready when development growth is imminent or if project funding becomes available from outside sources. A construction schedule has not been set for this project.
