Preferred alternative

MnDOT has selected a preferred interchange alternative, the Diverging Diamond Interchange (DDI) alternative. See the layout (PDF, 9 MB). The DDI best addressed the project purpose and need as well as stakeholder input. Also see a simulation of projected 2035 traffic volumes flowing through the DDI (MP4, 77 MB) or view a low-resolution version (17 MB WMV).
