The Alex Fraser Bridge (AFB) and approaches represent a critical link in the Highway 91 corridor system. Carrying an average of 119,000 vehicles daily, this area is an important commuter and goods movement route that was experiencing significant traffic congestion during peak periods of travel.
The bridge was originally designed to allow for the number of lanes to be increased. Binnie acted as Owner’s Engineer and Lead Engineer throughout the AFB capacity improvement project which prioritized the reconfiguration of the existing six lanes to accommodate a seventh lane and introduced an innovative moveable barrier system that uses a special vehicle that travels along the bridge, moving the barrier to improve capacity and help reduce congestion during peak periods.
With favourable feedback from the motoring public, this project is the first application of a movable barrier counterflow system in all of western Canada.
