Rehabilitation Work of the North Runway

Information and Updates

In order to maintain its facilities to reliability and safety standards, ADM must carry out work for the rehabilitation of the north runway.

The work at both ends of the runway has already been completed and some work for the rehabilitation of the central section was carried out in 2022.

In 2023, work to complete the rehabilitation of the central section of the runway and work on Taxiway B and access roads that service the runway are scheduled in order to finalize the rehabilitation project of the north runway.

The work will be carried out in 2 phases:

  • From March 13 to June 23 – North runway closed
    The rehabilitation work of the north runway consists of building new concrete slabs on the central section of the runway which is still in asphalt as well as the associated electrical works. The reconstruction of 2 access roads to access the north runway (excavation of the existing surface, reconstruction of the infrastructure and asphalt surface) is scheduled as well as the completion of work started in 2022 on another access road.
  • From September 11 to November 17 – Work on Taxiway B that services the north runway
    The runway will remain operational during the work, however runway use will be modified in northwesterly winds. Further information will be sent by a Soundscape Newsletter in September. The work consists of finalizing the reconstruction of an access road as well as carrying out work on a lane parallel to the runway. (Excavation of the natural ground, construction of the infrastructure including drainage and finalization in concrete slab and electrical work).

Aircraft access the North Runway via Taxiway B that is connected to the runway by several access roads as shown below:




The alternative departure procedures that were put in place in 2022, will continue to be used during the work this year.

During the closure of the north runway in the spring of 2022, NAV CANADA put in place alternative departure flight paths to ensure fluidity of operations in peak hours.

For safety reasons, NAV CANADA kept these alternative departure flight paths available during the winter transition. Indeed, it is preferable for air traffic control units to limit changes to procedures for short periods of time, considering the workload and training required.

In March 2022, ADM and NAV CANADA held four virtual information meetings to inform citizens on the alternative departure procedures during the work. For additional information on these procedures, we invite you to watch the recordings or to read the presentations of the meetings and the FAQ below.

Information and update on the runway rehabilitation project:

The work was divided into 4 phases and this year we are carrying out the final phases to complete the runway rehabilitation in 2023. At the end of the project, the runway will be completely redone in concrete and will not require major work for about twenty years. Concrete is a more resistant and durable material and maintenance work on concrete runways is done faster, which reduces runway closures. Updates will be posted below on the progress of the work.

Work area from March 13 to June 23, 2023:



Update - April 3, 2023

Work started as planned on March 13.

Project milestones include:

  • Work mobilization.
  • Demolition of transitions from previous phases and roads to be rebuilt.
  • Preparatory work for concreting the runway.
  • Concreting the runway in sections.
  • Reconstruction of access roads.
  • Post-concreting electrical and finishing work.
  • Runway reopening on June 23, 2023.

Weather permitting, two crews will work day and night, seven days a week. At peak times, there will be around 200 workers on site.

Two concrete plants were installed on the YUL site at the start of the project to ensure a high rate of concreting. These plants will provide a rapid supply of concrete during pouring periods and reduce truck trips.

In addition, material removed from the runway is being reused. In 2022, 99.7% of this material was reused, either on the airport site or elsewhere.
