The City of London is reconstructing Adelaide Street North from Elias Street to 80m north of McMahen Street, as well as Central Avenue from William Street to Elizabeth Street. The project will add an underpass beneath the CP Rail tracks, as well as nearby intersection improvements and active transportation connections, with wide multi-use paths on both sides of the roadway on Adelaide Street North.

Improvements to this civic boulevard rail crossing will provide improved pedestrian, cyclist, and transit user amenities consistent with Complete Streets principles.

This project will directly improve safety and reliability by eliminating the at-grade crossing, reduce cut-through traffic in nearby neighborhoods and improve active transportation and quality of life. There are also benefits associated with improving emergency service and transit reliability associated with the current at-grade crossing.

We acknowledge with gratitude the financial support provided by the Government of Canada and the Province of Ontario for the Adelaide Underpass project through the Investing in Canada Infrastructure Program (ICIP): Public Transit Stream.

Project Status

Construction began in spring of 2022, and is scheduled for substantial completion by fall of 2024, with some carryover work in 2025. Upcoming milestones include:

• Reopening of one lane in each direction under the underpass (April 2024)
• Reopening all traffic lanes under the underpass
• Completing active transportation components
• Restoration of park amenities

Information about project milestones will be released as timing is confirmed and can be found on london.ca/newsroom.

Traffic Impacts

Northbound and southbound traffic on Adelaide Street North will continue to use the temporary bypass road until the new vehicle lanes under the underpass permanently open.
