​Dunlop, Anne & Sunnidale – Highway 400 Improvements

The Ministry of Transportation (MTO) has initiated detailed design for the replacement of the Dunlop Street interchange/highway crossing, Anne Street highway crossing and Sunnidale Road highway crossing.

MTO has retained McIntosh Perry Ltd. to complete detailed design for the above noted improvements. The scope of work includes replacement of the Dunlop Street interchange and highway crossing and the Anne Street and Sunnidale Road highway crossings. The proposed replacement structures will reduce traffic congestion and accommodate planned growth through the addition of vehicular lanes, bicycling and sidewalk infrastructure.

Project Coordination

MTO is the proponent for this project, however the City is a key stakeholder. The City and MTO are working collaboratively to incorporate transportation improvements that support the needs of both local residents and the travelling public at large. These improvements will enhance the transportation network and help mitigate traffic congestion.
