The primary scope of the project was the reinstatement of Highway 1 infrastructure east of Lytton, BC, following extensive damage from the 2021 flood events.
The work included constructing two mechanically stabilized earth (MSE) walls using approximately 1,000 precast panels and 30,000 m³ of backfill, along with road structure construction, fine grading, installation of permanent drainage systems, offsite aggregate production, and reclamation of the existing highway detour.
Successful delivery required detailed planning and coordination to maintain safe operations and meet an aggressive paving schedule while executing multiple work fronts concurrently.
In support of the overall highway improvements within the Thompson Canyon, the project also included the construction of road detours, an overpass‑approach precast panel MSE wall, and all associated drainage and surfacing works. These activities were completed through both day and night shifts to maintain schedule. The project area was situated adjacent to the CPKC rail lines, necessitating strict rail safety protocols, the use of spotters, and coordination with CPKC to ensure work progressed safely and without disrupting rail operations.
