The Ontario Ministry of Transportation (MTO) has completed 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 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 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 followed the approved planning process for a Group 'B' project under the MTO Class Environmental Assessment (Class EA) for Provincial Transportation Facilities (2000). A Transportation Environmental Study Report (TESR) was prepared which provides information on the process that has been followed leading to the selection of the Recommended Plan, the environmental effects and proposed mitigation measures, as well as the technical findings of the study.

The TESR was made available for a 30-day public and agency review period which ended on December 19, 2015. Comments received during the review period have been responded to, and the Ministry of the Environment and Climate Change (MOECC) has confirmed that no Part II Order requests were received during the 30-day public and agency review period for the TESR review. Therefore, the study is considered to have met the requirements of the MTO Class Environmental Assessment (EA) for Provincial Transportation Facilities (2000).
