From the MTO's Southern Highways Program, 2008-2012:
The Ontario Ministry of Transportation, in partnership with Transport Canada, the U.S Federal Highway Administration and the Michigan Department of Transportation, is leading the Canadian portion of the Detroit River International Crossing study, to seek a long-term solution to border transportation issues in the Windsor area. The study is considering the entire border transportation system — river crossing, inspection plazas and access roads — to achieve an end-to-end solution that will best meet current and future mobility needs, while minimizing impacts on the surrounding communities and environment. The study team announced the technically and environmentally preferred alternatives for the access road, plaza and crossing in Spring 2008 and will submit environmental assessment documents for approval later this year.
The recommended solution includes the Windsor-Essex Parkway, which follows the existing Highway 3 corridor and then is located adjacent to the E.C. Row Expressway, to a new plaza and crossing in the industrial area of west Windsor. Target for completion of the entire system is 2013.
