Environmental Assessment Study

The Ontario Ministry of Transportation (MTO) has retained AECOM Canada Ltd. (AECOM) to undertake a Preliminary Design and Class Environmental Assessment Study for Highway 403 and Highway 6 Interchange infrastructure renewal. The Study limits extend from Grindstone Creek westerly to Old Guelph Road on Highway 403, and from Highway 6 and Highway 403 interchange to Bruce Trail on Highway 6. The Study encompasses fourteen bridges, three structural culverts, and fifteen retaining walls along Highway 403 and Highway 6. Reasonable design alternatives for structural and operational improvements will be developed and evaluated leading to the selection of a preferred alternative(s) for short-term and long-term improvements to ensure the next round of infrastructure rehabilitation/renewal can accommodate future traffic needs of Highway 403 within the Study limits.

The Study Area is located within the City of Hamilton and the City of Burlington (Halton Region).
