The Ontario Ministry of Transportation (MTO) is undertaking a Class Environmental Assessment and Preliminary Design Study (G.W.P. 10-20011) along the 25 km stretch of Highway 401 from Brock Road in the City of Pickering to Courtice Road in the Municipality of Clarington. The primary focus of this study was to confirm the rehabilitation needs of the corridor. In parallel, the Study Team confirmed 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 project limits are located within the City of Pickering,Town of Toronto, Town of Ajax, Town of Whitby, City of Oshawa, and Municipality of Clarington.

The long-term vision for the corridor includes the extension of the 12 lane core-collector system from Brock Road to the Highway 407 West Durham Link, and widening of Highway 401 to 10 lanes easterly from the Highway 407 West Durham Link to Courtice Road. In addition, modifications to each of the interchanges along this section of the highway are required to accommodate the proposed widening and provide adequate traffic operations.

The section of Highway 401 between Salem Road and Brock Street was reviewed and approved as part of a separate study (W.O. 09-20009) that considered the capacity, operational, and safety needs of that section of Highway 401. The study also included the integration of the planned improvements for the Highway 407 West Durham Link connection to Highway 401 and a new Lake Ridge Road interchange. The recommended plan for this study (G.W.P. 10-20011) incorporates the recommendations from the Salem Road to Brock Street study.

This study will follow the approved planning process for a Group 'B' project under the MTO Class Environmental Assessment (Class EA) for Provincial Transportation Facilities (2000).

The purpose of this website is to provide interested parties with access to project information and access to the Project Team that is carrying out this study.
