LONDON, Ont. – The latest update on a long-demanded railway underpass project on Adelaide Street in London, Ont. shows that work is on schedule to be completed by 2025.

The underpass was approved in 2018 with a budget of $88 million, with city council unanimously agreeing to move forward on the project following years of bottlenecked traffic and travel delays caused by two railway lines crossing the street.

Prior to the project, average delays from the train crossing caused more than 100 minutes of blocked traffic per day.

Construction began in 2022 and is being led by the City of London in collaboration with the Canadian Pacific Kansas City Railway, the owner of the interfering railroads. General contracting on the project is being carried out by McLean Taylor Construction Ltd.


The second phase of the project, which began this spring, is estimated to take two years to complete. It involves the installation of a new rail bridge, which took place from August to early September.

The first phase of the project was completed in 2022 and saw the installation and replacement of underground infrastructure, the developing of a pump station and storm sewer system to prevent onsite flooding and constructing a detour road for drivers.

The completed underpass will also include multi-use paths on both sides of the street to improve safety.
