The Bradford Bypass is a new 16.3-kilometre, controlled access freeway connecting Highway 400 in the County of Simcoe and Highway 404 in the Regional Municipality of York.

When complete, the freeway will extend from Highway 400 between 8th Line and 9th Line in Bradford West Gwillimbury, cross a small portion of King Township and connect to Highway 404 between Queensville Sideroad and Holborn Road in East Gwillimbury.

Preliminary Design for the Project has been completed and documented in the Environmental Impact Assessment Report available on the Previous Environmental Studies section of the website.

Bradford Bypass West extends from Highway 400 to Simcoe Road 4. It includes a four-lane divided mainline freeway with grass median, two interchanges (10th Sideroad and Simcoe County Road 4), and a freeway-to-freeway interchange (Highway 400/Bradford Bypass).

The Ontario Ministry of Transportation has retained AECOM Canada Ltd. to carry out an Environmental and Detail Design study for the western section of the Bradford Bypass.

The Environmental and Detail Design study includes additional field investigations, including natural science, fisheries, and archaeological assessments. When available, reports and opportunities to comment on the work completed as part of the Detail Design Study will be made available on the Detail Design Study section of the website.

Timing for construction of the Bradford Bypass West is being reviewed as part of this Detail Design Study. Updates regarding Project construction will be made available as they are known and will be posted on the Project Website.

Fieldwork for the West section of the Project is ongoing and includes entry to properties to record existing conditions and obtain other relevant information pertinent to completing detail design of the highway.

While some of the required investigations are non-intrusive, other investigations such as test pits, boreholes, and ploughing will result in some minor disturbances.  If there is any disturbance or alteration to property, as a result of the investigations, property will be restored to original conditions at no cost to property owners.  

Investigations will take place on an intermittent basis until detail design of the highway is complete (which could occur through to December 2026). Investigations will generally occur during day-time hours during the week (Monday to Friday), however some surveys do require conditions be documented during dawn and dusk hours.

MTO are reviewing opportunities for advancing work on the rest of the Bradford Bypass. Updates will be made available once they are known.

Consultation is ongoing process, which is an integral and critical component to a project’s success. The Project Team strives to provide consultation opportunities that are inclusive, timely, that and provide stakeholders with the ability to provide meaningful input to the outcome of the study. Engagement and consultation include:

• Access to general information and consultation through the Project Website (bradfordbypass.ca);
• Access to general communication through Project Telephone Line (1-877-247-6036);
• Inclusion, by request, on the Project Contact List to receive regular project updates and to have the Project Team consult with the correct individuals;
• Receive email communications and contact the Project Team through a dedicated Project email (projectteam@bradfordbypass.ca);
• Receive project specific Mailings and notifications (via physical mail or email);
• Newspaper advertisements;
• Public Information Centres throughout the study (next one in 2025); and
• Indigenous community information centres, and meetings, and correspondence with Chiefs and Councils, or their delegates, as requested.

Comments and questions regarding the Project are being accepted at any time through the Contact Us.

Notices will be shared with stakeholders on the Project Contact List to let them know of future opportunities such as Public Information Centres and opportunities to review Study documentation. These opportunities will also be advertised through the Project Website.
