Project purpose and background

The Mackenzie King Bridge is a set of four continuous bridge structures that span from Elgin Street to Nicholas Street. The project includes the rehabilitation of three of the four structures. Those are:

  • National Arts Center (NAC) Structure
  • Rideau Canal Structure
  • Steel Viaduct Structure

The fourth structure, Nicholas Street Overpass, is in good condition and does not require structural rehabilitation at this time.

The project involves the rehabilitation of the roadway on Mackenzie King Bridge, from Elgin Street to Nicholas Street. The project includes reconstruction of streetscape elements and transportation components within the Mackenzie King Bridge right of way based on the following completed studies:

  • A Detailed Condition Assessment and Renewal Options Report was prepared in July 2017.
  • The post Light Rail Transit (LRT) repurposing Functional Design Study which included repurposing the bridge deck was completed in January 2019.

Key project aspects:

  • Rehabilitation of three (3) connected bridge structures.
  • Rehabilitation / replacement of expansion joints, concrete repairs, waterproofing, drainage structures, and other lifecycle renewal requirements.
  • Reconstruction of streetscape elements and transportation components.
  • Reconfiguration of the roadway from a four-lane road to a two-lane road, with raised cycle tracks and widened sidewalks.
  • Public spaces that integrate benches, waste receptacles, bike rings / bike racks, and granite stools.
  • Median bike lane improvements near the east project limit, on the west side of the Nicholas Street / Waller Street intersection.

Traffic and transit impacts

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

Some bus stops along the bridge within the existing mid-block signalized pedestrian crossing will be temporarily relocated to the east during construction. OC Transpo and STO bus service across the Mackenzie King Bridge in both directions will be maintained, including pedestrian access to bus stops. Visit OC Transpo’s website for more information.

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.
