Highway 29 Realignment

Fort St. John, British Columbia

The creation of the reservoir for the Site C Clean Energy Project will widen the Peace River by two-to-three times, significantly flooding sections of Highway 29, a crucial link connecting Hudson's Hope with the Alaska Highway and Fort St. John. BC Hydro partnered with the BC Ministry of Transportation and Infrastructure and retained WSP Canada to develop and implement design solutions for five replacement bridges spanning 150m to 1042m in length. These bridges had to overcome many complex and difficult technical challenges, including poor ground conditions prone to debris flows and slides, and significant fluctuations in local climate, wind patterns, and hydrology before and after reservoir formation.

The use of one versatile design to streamline construction across multiple sites earned high marks from the jurors. They also applauded the exemplary project management that allowed the team to successfully navigate diverse environmental challenges and stringent time constraints.
