Rehabilitation of the Trail 54 bridge

Located in Gatineau Park, Trail 54 bridge provides access to the Lusk Lake Shelter for users and maintenance vehicles. The steel structure supporting the bridge is in good condition. However, its wooden deck and abutments are showing significant signs of decay due to rot. Intervention is required to ensure the integrity of the bridge. The bridge requires major repair work in 2023 to keep the pathway open to the public and maintenance personnel.


No tree cutting is planned to complete the work. The work will take place during the low risk period for fish and fish habitat. The NCC will request a letter of advice from the Department of Fisheries and Oceans to complete the work near the creek. The site will be rehabilitated following the work.


Construction is scheduled to begin mid-summer 2023, with completion in the fall of 2023.



  • Ensure continuity of access to Trail 54;
  • Maintain the bridge in a safe condition for all users, contractors and NCC staff; and
  • Reduce the need for temporary maintenance and repairs.


The construction phases include:

  • Closure of Trail 54 and installation of required signage;
  • Mobilization of the contractor at the edge of the bridge;
  • Dismantling the existing bridge;
  • Correction work on the abutments;
  • Construction of the bridge deck;
  • Construction of bridge railings;
  • Re-vegetation and seeding of banks as required; and
  • Site restoration, including trail approaches.
