Winchester Road Widening Project Announced in Whitby
The Regional Municipality of Durham has announced the rehabilitation and widening of Winchester Road (Regional Road 3) from Durham Street/Chelmsford Drive to east of Watford Street/Anderson Street in Whitby. The project includes several key components:
- Widening Winchester Road to include a center two-way left turn lane, in addition to the existing one eastbound lane and one westbound lane.
- Replacing the concrete sidewalk on the north side of Winchester Road.
- Constructing a 3.0-meter asphalt multi-use pathway on the south side of Winchester Road.
- Rehabilitating and widening the Lynde Creek bridge.
- Restricting right-turn only for vehicles traveling southbound on Durham Street at Winchester Road.
- Installing a traffic control signal to facilitate pedestrian crossings at the Winchester Road and Durham Street/Chelmsford Drive intersection.
- Improving traffic signal accessibility at the Simcoe Street pedestrian signal and the Watford Street/Anderson Street intersection.
Construction is expected to begin in Summer 2024 and be completed by late 2025. During the construction period, Winchester Road will be closed to eastbound traffic from August 6, 2024, to December 2024, and again from April 2025 to December 2025. One westbound lane will remain open throughout the construction.
Eastbound traffic will be detoured northbound on Ashburn Road, eastbound on Columbus Road E., and southbound on Thickson Road. Short-term lane closures with traffic controlled by flagging operations will also occur. Businesses will remain open, and access to all businesses and residential properties within the work zone will be maintained using the westbound lane. Short-term sidewalk closures will be required to facilitate construction.
Local streets within Brooklin are being reviewed for traffic calming needs. Mitigation measures under consideration include the use of portable radar message feedback signs, installing “local traffic only” signage, and adjusting traffic signal timing plans to help maintain traffic flows.
