York Street and Wellington Street Infrastructure Renewal Project

Closure update

Work at the York and Wellington intersection is continuing. While the intersection was originally expected to reopen by Thanksgiving, the new target reopening date is Tuesday, October 14. The section between Clarence and Wellington is also expected to reopen by the end of November.

The delay is due to unexpected underground utility conflicts and an unanticipated concrete foundation extending into the intersection, which required adjustments to the work plan. Surprises like this can happen in the downtown core, where older infrastructure and incomplete historical records are common. In these cases, the project team adapts quickly to keep progress moving.

Looking ahead, work will continue into 2026 as planned, with a focus on York Street between Wellington and Colborne.

This project is replacing very old combined sewers, some more than a century old and built with brick and mortar. Along with improving the health of the Thames River, these upgrades will increase sewer capacity to support London’s growing population.

Construction background

Starting Wednesday, July 2 (weather permitting) through the Labour Day weekend, Wellington Street will be fully closed from King Street to Horton Street, including the underpass, to allow for important work as part of the York Street Infrastructure Renewal Project.

Access will be maintained through the east side of the York and Wellington intersection, allowing westbound travel from the east side of York Street.

During the closure, the intersection at Horton Street and Wellington Street will stay open for east and west traffic. There will be no northbound general traffic permitted through the intersection.

Bathurst Street will remain open for local access to the Salvation Army London Centre of Hope and other business destinations.

About the project

The City is replacing aging infrastructure that has met its expected lifecycle, which involves removing existing combined sewers along York Street. In addition to helping improve the health of the Thames River, this work is necessary to support a growing population by increasing sewer capacity for intensification and development. Utility upgrades is another key project component, ensuring continued operation and reliability of our hydro, energy and communications systems.
