The Minnesota Department of Transportation plans to reconstruct the intersection of I-94 and Hwy 75. In addition, auxiliary lanes are planned on I-94 between Hwy 75 and 20th Street.

The project will be designed to improve mobility and safety through the interchange and reduce delays on both Hwy 75 and I-94.

The project is based on a June 2008 study on Hwy 75 and 20th Street in Moorhead. Click here to review the study (30 MB PDF)

Preferred alternative

MnDOT has selected a preferred interchange alternative, the Diverging Diamond Interchange (DDI) alternative. (Click here for 9MB PDF of the layout.) The DDI best addressed the project purpose and need as well as stakeholder input. A simulation of projected 2035 traffic volumes flowing through the DDI can be viewed at at this link (77MB MP4) or a low-resolution version can be viewed here (17 MB WMV).
