NOTICE OF COMPLETION 
PLANNING, PRELIMINARY DESIGN AND CLASS ENVIRONMENTAL ASSESSMENT
Highway 401 Nagle Road Interchange Study, GWP 4059-17-00

Cobourg, ON (January 14, 2025) – The Ontario Ministry of Transportation (MTO) and Town of Cobourg (Town) have undertaken a Planning, Preliminary Design, and Class Environmental Assessment (Class EA) Study for a new Highway 401 interchange with Nagle Road within the Town and the Township of Hamilton. The Town initiated this study to develop a Recommended Plan for a new interchange to support the transportation objectives set forth in the Town’s Official Plan and future growth within the Cobourg East Community Secondary Plan area.

THE RECOMMENDED PLAN
Based on the findings of this Class EA Study, the Recommended Plan includes the following:

• Replacement of the existing Nagle Road bridge with a new, four-lane bridge including a sidewalk on the west side and a dedicated cycling lane on each side of the new bridge
• Construction of a new Parclo A2/Diamond interchange at Highway 401 and Nagle Road
• Widening of Nagle Road from two lanes to four lanes from approximately 400m north and south of Highway 401.

The Recommended Plan may be constructed in several phases to accommodate bridge rehabilitation/replacement needs and development growth. As part of the first phase, the new bridge may be constructed with only two vehicular lanes, with provision for widening the bridge in the future. The timing of each phase will be dependent on the bridge condition and the actual timing of development within the Cobourg East Development Plan area.

THE PROCESS
This study was completed as a “Group B” project under the Class EA for Provincial Transportation Facilities (2000). A summary of the study process, including the identification and evaluation of alternatives, the Recommended Plan, anticipated environmental impacts, proposed mitigation measures, and consultation activities carried out as part of this study, has been documented within a Transportation Environmental Study Report (TESR), a copy of which is available for public comment between Monday, January 20, 2025, and Wednesday, February 19, 2025.

REQUESTS TO THE MINISTER OF ENVIRONMENT, CONSERVATION AND PARKS
In addition, a Section 16 Order request may be made to the Minister of the Environment, Conservation and Parks for an order requiring a higher level of study (i.e., requiring comprehensive EA approval before being able to proceed), or that conditions be imposed (e.g., requiring further studies), only on the grounds that the requested order may prevent, mitigate, or remedy adverse impacts on constitutionally protected Indigenous and treaty rights. Requests on other grounds will not be considered. Requests should include the requester’s contact information and full name, as well as the project and proponents’ names.

Requests should specify what kind of order is being requested (request for additional conditions or a request for an individual/comprehensive environmental assessment), how an order may prevent, mitigate or remedy potential adverse impacts on Indigenous and treaty rights, and any information about efforts to date to discuss and resolve concerns, and in support of the statements in the request. This will ensure that the ministry is able to efficiently begin reviewing the request.

The request should be sent in writing or by email to the following as well as to the project contacts above:
