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.
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 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.
