The Rt. Hon. Herb Gray Parkway is the Canadian freeway portion of a new international crossing between Windsor, Ontario and Detroit, Michigan that is adjacent to a rare Tallgrass prairie ecosystem. The Parkway is the first provincial highway project to require locally sourced plant material and to use exclusively native seed mixes. It is the largest landscape installation associated with a provincial highway to date. Presentation by Barb Macdonnel of the Ontario Ministry of Transportation.
