The primary focus of this study is to confirm the rehabilitation needs of the corridor. In parallel, the study is being completed to confirm the long-term capacity and operational needs so that rehabilitation investments can be made with an understanding of the long-term vision for the corridor. The study limits include Highway 401 from Brock Road to Courtice Road, excluding the portion between Salem Road and Brock Street. The project limits are located within the City of Pickering, Town of Ajax, Town of Whitby, City of Oshawa, and Municipality of Clarington.
A wide range of mainline and interchange alternatives have been developed and evaluated to determine the most appropriate solution.
