Pattullo Bridge is an important link over the Fraser River in Metro Vancouver, linking over one million residents on Burrard peninsula to communities to the east. Opened in 1937 with a design life of 50 years, the bridge helped support economic and population growth in the region. 75 years later, TransLink, the Regional Transportation Authority, is leading a project to replace this aging structure.

Alta is developing active travel connections to, from, and over the new structure. The bridge has an 80 km/h (50 mph) speed limit and a 1.8m (6ft) wide sidewalk on one side that carries two-way traffic. The design for the new structure and its connections is predicated on best practices from around the world and an optimistic demand estimate of 1,800 users per day by 2040. As part of the study, Alta has undertaken a best practices review of over a dozen bridges throughout North America and Europe, looking at how best to accommodate active travel on and connecting to bridge structures.
