On April 9, 2010, the City of Windsor, along with local cabinet ministers Dwight Duncan and Sandra Pupatello of the Province of Ontario, announced a final decision had been made in the plans to construct the Windsor-Essex Parkway, the new Highway 401 extension leading to a future crossing. The announcement indicated the project will be the most expensive road ever built in Canada on a per kilometre basis, and included commitments to enhance green space design through the use of berming, landscaping, and other aesthetic treatments. As part of negotiations with the City of Windsor (who threatened legal action in pursuit of more tunneling and green space of the route), the province agreed to additional funding to infrastructure projects in Windsor-Essex; this includes money for the improvement to the plaza of the Canadian side of the Windsor-Detroit tunnel, the widening and other improvements of Walker Rd between Division Rd and E.C. Row Expressway, and the environmental assessment and preliminary design of a future extension of Lauzon Parkway to Highway 401.
