MnDOT proposes upgrading the Highway 24 interregional corridor connection to a freeway between I-94 in Clearwater and Highway 10 in Clear Lake in Wright and Sherburne Counties.


The need was initially established in a transportation study completed in 1996; and a range of potential connections were evaluated in a Mississippi River Crossing Study conducted between 1995 and 1996. As a result, four potential corridors were recommended for further study and were eventually narrowed down to four specific alignments, which are documented in the 1997 I-94/Highway 10 Regional Connection Scoping Document and the 2001 Scoping Decision Document.


During the Draft Environmental Impact Statement (DEIS) process, the scoping alignments were further refined with respect to interchange configurations and system connection issues. A number of sub-alternatives were developed and evaluated, ultimately resulting in identification of four build alternatives (one in each of the alignments carried forward from scoping) that were analyzed and documented in detail in the DEIS.


The DEIS was prepared to:


In May 2004, MnDOT announced the selection of Alternative C as the preferred alternative, which best met the region's transportation needs while minimizing environmental, social, and economic impacts. The preferred alternative is a freeway design with interchanges proposed at I-94 and Highway 10, and a grade-separated rail crossing near Highway 10. It will tie into Interstate 94 approximately 2 miles southeast of the existing Highway 24 interchange at Clearwater and continue on a new alignment across the river. The alignment would continue north at the location of the existing 70th Street to intersect with Highway 10 approximately 1 mile northwest of the existing Highway 24/Highway 10 intersection in the city of Clear Lake. An interchange is also proposed at the intersection of the preferred alternative with existing Highway 24 to provide local access to the river crossing for Clearwater and Clear Lake area traffic.


Detailed layouts for the preferred alternative are complete. The Final Environmental Impact Statement (FEIS) documents the revisions to the preferred alternative and was available for public review and comment in early 2007.


The Record of Decision was completed by the Federal Highway Administration in September 2007. The Adequacy Determination was completed by the MnDOT Office of Environmental Services in October. These documents complete the environmental review process and is available for viewing.
