Sunningdale Road Environmental Assessment
Sunningdale Road is a two-lane street in north London where traffic volumes are steadily increasing, and road improvements are required to meet travel demand. Major intersections along the road are already beginning to experience operational challenges due to high traffic volumes and turning movements, including at Wonderland Road, Richmond Street, and Adelaide Street, where the existing conditions warrant improving the intersections.
This Environmental Assessment was initiated to explore solutions to address challenges along Sunningdale Road, between Wonderland Road North and Adelaide Street North, including safety, traffic congestion, comfort and convenience, speed and travel time.
Through the Environmental Study Report, a number of improvements were recommended for Sunningdale Road that aligned with the Transportation Master Plan, including:
The Environmental Assessment is complete, and Council approved the plan in June 2012. The recent Development Charges Background Study (2021) identified the segment between Wonderland Road and Richmond Street to be constructed in 2023, and the segment between Richmond Street and Adelaide Street to be constructed in 2025.
After careful assessment during the detailed design stage of the project, it was determined that a deferral of the Wonderland Road to Richmond Street construction is required, as further work is needed to obtain agreements and approvals related to an Imperial Oil pipeline traveling beneath a section of the roadway. The further work will ensure that the project can be completed in a cost-effective manner and in compliance with provincial requirements.
To progress the project, the planned work at the Sunningdale Road and Richmond Street Intersection will be completed as a stand-alone project. The project is targeted for construction in 2024 and will include the following features:
Sunningdale Road Construction Phases*
*Construction phases are subject to approvals and agreements.
The City sent out a notice of commencement to residents, business owners and interested stakeholders to notify them of the Environmental Assessment's start.
A Public Information Centre was scheduled for October 2009 - interested parties were encouraged to attend. They provided comments specific to the potential realignment of Commissioners Road West to the project team, which were critical to the development of this environmental assessment.
A Public Information Centre was scheduled for November 2011. The team provided all interested parties with an update on the project and listened to feedback that was critical to shaping the recommendations provided by the Environmental Study Report.
The Environmental Assessment is now complete, and Council approved the plan in 2012.
The project is now in detailed design.
