A phased approach is being used for implementation of the Project.
The first phase was the replacement of the Concession Road 7 Bridge over Highway 401 which was completed in 2020.

Phase 2 of the study includes the construction of the Highway 6 / Hanlon Expressway Midblock Interchange, a new interchange on Highway 6 (Hanlon Expressway) north of Highway 401 which was completed in 2025.

Phase 3 of the study includes the Environmental Assessment, Design and Construction of the Highway 401 and Highway 6/Brock Road South Interim Interchange Improvements. Phase 3 is currently following the approved planning process for Group B Projects under the Class Environmental Assessment for Provincial Transportation Facilities and Municipal Expressways (2024).
