Planning, development and construction

Beginning on Wednesday, July 27, the Mackenzie King Bridge will be reduced to one lane in each direction for the duration of the Mackenzie King Bridge Renewal project. When the project is complete in approximately August 2024, the four-lane bridge will be renewed with two-lanes, raised cycle tracks and widened sidewalks.

Workers will be rehabilitating the three connected bridge structures including the rehabilitation and/or replacement of expansion joints, concrete repairs, waterproofing, drainage structures and other lifecycle renewal requirements as part of this important project.

Traffic impacts

The majority of the construction work will be done in stages. During construction, one travelling lane in each direction (eastbound and westbound) will be open at all times.

Access to all businesses and properties will be maintained and pedestrians and cyclists will be accommodated through the work zones.

Transit impacts

OC Transpo and STO bus service across the Mackenzie King Bridge in both directions will be maintained, including pedestrian access to bus stops. The bus stops on the Mackenzie King Bridge near the signalized pedestrian crossing may be temporarily relocated to accommodate construction. Use OC Transpo’s Travel Planner to plan your trip. For more information visit or call 613-560-5000.

Pedestrian impacts

Pedestrian crossings will be maintained around the work zone. Pedestrian access to private properties, the CF Rideau Centre south entrances, Department of National Defence and the Confederation Park staircase will remain open at all times during construction.
