Welcome to the project website for the replacement of three underpass structures on Highway 400 at Dunlop Street, Anne Street and Sunnidale Road in the City of Barrie, Simcoe County. Also included in the project is the reconstruction of the Dunlop Street and Highway 400 interchange, Highway 400 pavement resurfacing from Dunlop Street to north of St. Vincent Street, Bayfield Street ramp resurfacing, Highway 400 median barrier replacement, drainage improvements within the resurfacing limits, design of noise walls in the vicinity of Dunlop, Anne and Duckworth and provision for Highway 400 future full illumination. The project works are being designed to accommodate the future ultimate widening of Highway 400, which is beyond the scope of this project and is not currently programmed. The preliminary design of the bridge replacement options were previously completed as part of a 2017 Environmental Assessment.
