Background

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:

• widening the road from two to four lanes to meet the projected transportation requirements in the area, with auxiliary turn lanes at intersections where warranted
• intersection improvements at two major intersections (Wonderland Road and Adelaide Street)
• improving the Richmond Street intersection by adding left/right turn lanes
• cycling infrastructure throughout the Study Area
• sidewalks for both sides of Sunningdale Road
• a three-metre pathway under the Medway Creek Bridge to allow future connections to the east path system

Current status

The Environmental Assessment is complete, and Council approved the plan in June 2012. The recent Development Charges Background Study identified the Sunningdale Road improvements, between Wonderland Road and Richmond Street to be constructed in 2023. The Sunningdale Road improvements, between Richmond Street and Adelaide Street, were identified for construction in 2025.

After careful assessment during the detailed design stage of the project, it was determined that a deferral of construction on Sunningdale Road 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.

The timing for construction is currently being reviewed and it is subject to agreements and approvals.  Future project milestones and updates will be shared once the necessary approvals are confirmed.
