Highway 401 Planning Study from Cobourg to Colborne, and Highway 401 Nagle Road Interchange Study
Highway 401 Planning Study
Welcome to the Highway 401 Planning Study from Cobourg to Colborne. The Ministry of Transportation, Ontario (MTO) has retained Stantec Consulting Ltd. (Stantec) to complete a Planning, Preliminary Design, and Class Environmental Assessment (Class EA) Study on Highway 401 for the replacement and rehabilitation of structures, interchange modifications, future widening of the highway, and commuter parking lot expansions, from 2 km east of Nagle Road to Percy Street (approximately 18 km).
Nagle Road Interchange Study
Welcome to the Highway 401 Nagle Road Interchange Planning, Preliminary Design, and Class Environmental Assessment (Class EA) Study on Highway 401 for a new interchange near Nagle Road in the Town of Cobourg and the Township of Hamilton (GWP 4059-17-00). The interchange study is the Town of Cobourg’s initiative and is being completed concurrently with the MTO’s Highway 401 Planning Study from Cobourg to Colborne (GWP 4060-11-00).
News for: Nagle Road Interchange Study
2025-01-20 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 400 m 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.
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). The TESR is available for public comment between January 20, 2025, and February 19, 2025.
The TESR is available in the DOCUMENTATION tab above, and in person at the following location:

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.
