The Rt. Hon. Herb Gray Parkway

The Rt. Hon. Herb Gray Parkway is the approved access route connecting Highway 401 to a new Canadian inspection plaza and new crossing in west Windsor. Rt. Hon. Herb Gray Parkway will be the most significant single highway investment made in Ontario history. This project will lead to an estimated 12,000 project-related jobs, with the majority in the Windsor-Essex region.

The Rt. Hon. Herb Gray Parkway starts on Highway 401 at North Talbot Rd and stretches along the Highway 3/Huron Church Road corridor to E.C. Row Expressway and then joins the Expressway leading to the new approved plaza. This modern, state-of-the-art Parkway will support existing industry, attract new investment and create business opportunities in Windsor-Essex, Ontario and all of Canada. People and goods will travel safely and smoothly through this international corridor, sending a clear message that Windsor-Essex is open for business.

As with any construction project, the Ontario Ministry of Transportation (MTO) will ensure all necessary permits are in place for construction of Rt. Hon. Herb Gray Parkway. This includes permits under the Endangered Species Act 2007. Through ongoing field investigations and guidance from species experts we will continue to develop mitigation strategies which meet permitting requirements and ensure protection and, wherever possible, assist in recovery of species at risk.

Initial Construction

As a component of the Rt. Hon. Herb Gray Parkway, MTO completed the detail design of two bridges and a noise barrier. One bridge is located where Highway 3 will pass over the Rt. Hon. Herb Gray Parkway and the other will provide a future off-ramp from Highway 401 westbound to Highway 3 and the realigned Howard Avenue. Initial construction will also include approximately two kilometres of noise barrier, five metres high, adjacent to the Southwood Lakes community, from Howard Avenue to North Talbot Road. The noise barrier will help provide effective noise mitigation for the adjacent community. Initial construction started in December 2009 and is expected to take one year to complete.


Our 2010 demolitions have started. Jones Group of Essex County is working to demolish buildings on Spring Garden Road, Matchette Road, Malden Road, and Chappus Street. They previously completed demolition on Huron Church Road, Huron Church Line, and Sansotta Court including the former Sandcastle Recreation, Maxximus, Century Fire and all houses on Sansotta Court. The Canadian Group of Companies of Essex has completed demolition of buildings on Grand Marais Road, Huron Church Road and Lambton Street, including the Lambton Plaza, Daytona Car Wash, and King Kone Ice Cream. Further contracts may be released this fall.


A total of 900 properties are required for construction of the Rt. Hon. Herb Gray Parkway. MTO has helped hundreds of property owners through this transition so far and continues to work with hundreds more. Concerned property owners should contact the Ministry of Transportation, Windsor Border Initiatives Implementation Group at 519-973-7367 or 1-800-265-6072 ext. 4800 or email .

Private Sector Delivery

MTO is working in coordination with Infrastructure Ontario to deliver Rt. Hon. Herb Gray Parkway utilizing an Alternative Financing and Procurement (AFP) model, in which the private sector's expertise and innovation will be used to design, build, finance and maintain the Rt. Hon. Herb Gray Parkway.

Local Sourcing

The Rt. Hon. Herb Gray Parkway represents a significant economic opportunity for local workers, suppliers, and contractors. Local workers are expected to have a significant role to play through various stages of construction. It has been Ontario's experience that local sourcing happens naturally, and this project is expected to create thousands of project-related jobs, with the majority in the Windsor-Essex region. MTO and Infrastructure Ontario are working with the local construction industry to foster opportunities for local participation.
