Chinook Pedestrian Bridge Overpass

Project Overview

The public side of the Chinook pedestrian +15 bridge is a fully enclosed bridge crossing over MacLeod trail SW along 61 Avenue SW. A pavilion building on each side of McLeod Trail provides access to the bridge level by escalators, stairs, and an elevator. The bridge replaces the ground-level pedestrian crossing on McLeod Trail, helping to reduce traffic congestion.

The exterior building envelope consists of curtain wall glazing, aluminum composite panels, and SBS/PVC roofing. The interior finishes comprise polished concrete and tile flooring, masonry veneer walls, and acoustic and metal-panel tile ceilings.

MacLeod Trail, which acts as a major public commuter roadway, was a challenging location for construction of the 190-foot bridge. With the steel bridge structure too large to transport as one piece, the project team successfully developed a fabrication area in the mall parking lot from which smaller sections of the bridge were transported to the site and assembled into the full 190-foot span. Upon assembly of the steel section, the bridge was transported onto MacLeod Trail with a SPMT crawler and lifted in tandem by two mobile cranes. The team used 3-D shop drawings and scanning methods to ensure that all elements fit together properly, a necessity given that the project was located in the road easements of a major road intersection and each pavilion building has unique architectural features.

Selecting PCL as the general contractor for both the public and private side of the bridge created savings for the City of Calgary and Cadillac Fairview, owing to the interconnected components and the ability to have one contractor manage both contracts.
