Completing the Calgary Ring Road for the Alberta Ministry of Transportation involved enhancing transportation infrastructure and improving travel efficiency for Albertans. As part of this endeavor, twinning the NW Stoney Trail bridge over the Bow River was required to alleviate traffic congestion and minimize delays. Stantec designed a new 470m-long, five-span bridge over the Bow River, directly west of the existing Stoney Trail bridge. The bridge employed an innovative segmental cast-in-place technique using a balanced cantilever method— allowing for bridge construction within a small working area.
The project’s ambitious use of concrete cantilever design impressed the jury. This technically challenging construction approach seamlessly integrated the two structures while also achieving continuity across different construction phases.
