Seacliff Drive East Reconstruction Project

As part of ongoing infrastructure improvements, the Municipality of Leamington is advancing the next phase of the Seacliff Drive East Reconstruction Project. During active construction, Seacliff Drive East will be closed to through traffic between Regatta Drive and Seneca Road, with work expected to begin in early February.

Stage 1 Construction Area and Access

The project is currently in Stage 1 of construction, which includes work along Seacliff Drive East from Regatta Drive to the west side of Seneca Road.

During Stage 1, access to businesses and properties will be maintained as follows:

• Businesses and properties between Erie Street South and Regatta Drive Access is available via Erie Street South and Seacliff Drive East.
• Businesses and properties between Seneca Road and County Road 33 Access is available via County Road 33 and Seacliff Drive East.
• Left turns from County Road 33 to Mersea Road 1 Left-turn movements will remain available during this construction stage.

Businesses within the project area will remain open and accessible throughout construction. Further notifications will be shared as construction progresses and work transitions into future stages.

Detours and Traffic Management

To safely accommodate construction, a signed detour route will be in place and clearly marked with orange construction and detour signage throughout the area. Detours will guide drivers around the closure using nearby collector and arterial roads.

What Drivers Can Expect

• No through traffic will be permitted within the active work zone.
• Local access will be maintained where possible for residents and businesses within the closure limits.
• Businesses remain open, with access provided via posted detour routes.
• Detour signage (D-1 and D-2 routes) will be installed in advance of the closure to allow drivers to plan alternate routes.

Motorists are asked to follow all posted detour signs, reduce speed in construction areas, and plan for additional travel time.

The Municipality thanks residents, businesses, and motorists for their patience and cooperation as this important infrastructure project moves forward.

The Municipality of Leamington is moving forward with the next phase of improvements to Seacliff Drive East. Construction is expected to begin in early February 2026 and will result in traffic interruptions, including lane restrictions, delays, and temporary road closures within the project area.

The work will take place between Regatta Drive and County Road 33.

This project is a key component of the Northeast Trunk Sewer initiative, a transformational infrastructure project that will help shape Leamington’s growth over the next four decades. By upgrading critical underground services now, the Municipality is laying the foundation to support future residential development, employment lands, and economic growth in a planned, sustainable, and responsible manner. The initiative is supported by $41 million in provincial funding and will help unlock the potential for up to 6,500 new housing units, while reducing reliance on aging or limited servicing capacity.

Timing and Traffic Impacts

Construction is anticipated to begin in February 2026 and is expected to be completed by fall 2026, weather permitting. Motorists are encouraged to avoid the area when possible and should expect traffic interruptions, including lane closures, delays, and temporary road closures throughout construction.

Project Updates

Project updates and traffic notices will be shared throughout the duration of the project at leamington.ca/SDER. Residents are encouraged to follow the page to receive project updates directly to their inbox.
