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 will be constructed in four major stages over the 2016 construction season.
The auxiliary lanes on I-94 will be constructed early in the season using overnight and weekend lane closures.
Hwy 75 between 24th Ave. and 30th Ave. will be closed to through traffic during the summer, but vehicles will be allowed to make right turns between Hwy 75 and I-94 except while individual ramps are reconstructed. For example, vehicles will be able to turn from southbound 75 to westbound 94 and from eastbound 94 to southbound 75. The primary Hwy 75 detour will be 40th Ave. to 20th St. to 12th Ave.
The work plan and detours for each stage is included below in PDF documents.

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).
