Scheduled Lane Closures on Winchester Road in Whitby

The Regional Municipality of Durham will begin reconstructing and widening Winchester Road (Regional Road 3) from Durham Street/Chelmsford Drive to east of Watford Street/Anderson Street in Whitby starting August 6, 2024. The contractor, Four Seasons Site Developments Ltd., mobilized in July 2024, with the project expected to be completed in the fall of 2025. There will be a winter shutdown period from December 2024 to April 2025, during which work will pause. Construction will resume in April 2025, with final completion anticipated in September 2025. All eastbound lanes on Winchester Road will be closed, and traffic will be restricted to one lane westbound between Durham Street/Chelmsford Drive and Watford Street/Anderson Street. Two-lane traffic will resume during the winter shutdown. From April 2025 to September 2025, traffic will again be reduced to one lane westbound. Detour routes will be established with signage directing traffic around the construction limits. The established detour is Highway 7, northbound on Ashburn Road to Columbus Road West eastbound to Thickson Road southbound to Winchester Road. Local traffic and emergency access will be maintained at all times, and sidewalk closures will be required, with pedestrian access available on either side of Winchester Road.
