Description

The Sanderling Drive Pedestrian Overpass in Calgary, Alberta, Canada is 109.90m long with a 64.40m clear span and no intermediate supports, providing motorists with an unobstructed view along the busy throughway. The overpass ties the pathways between two communities through a series of ramps, approximately 103m, with some curved sections. A continuous beam structural system was selected for this project, with the placement of bearing and expansion joint design to optimize the life cycle of the bridge components.

The bridge features a 33.5 m drop-in Ductal® girder produced and installed by Lafarge's Precast team in Calgary. This 49 m clear span bridge crosses over 6 lanes of traffic, providing the two adjacent communities with an aesthetically pleasing, durable curved-linear link. Ductal® was chosen for the girder because of its high compressive and tensile strength, allowing for a slender T‐section. During installation of the drop-in girder road closure occurred for just 8 hours.
The architect & engineer of record for this project is Cohos Evamy integratedesignTM. The client/owner, the City of Calgary, was actively involved by sponsoring the project and providing project management services during the design and construction phase. Graham Construction was the General Contractor.
