The Fort Nelson River Bridge project involved the replacement of the 430m single lane Acrow Bridge superstructure with a two-lane steel girder and concrete deck bridge for the Ministry of Transportation and Infrastructure (MOTI) on Highway 77. As part of the works, a detour route with bridge was required, as well as structural upgrades to the seven piers and both abutments, and the demolition and removal of the Acrow bridge following completion of the new structure.

DWB was retained by Forbes Industrial Contractors Ltd for both engineering and environmental services. This included design of the detour road, bridge, steel erection, and cast-in-place deck design, as well as the removal plan for the Acrow bridge superstructure. Quality and traffic management plans were developed and executed by the engineering department. The environmental department developed the Construction Environmental Management report, provided environmental monitoring services and reporting services.
