Main Span: 190 m (623 ft)
Bridge Length: 380 m (1,250 ft)
Width: 40.0 m (131 ft) to 44.660 m (146.5 ft) (seven traffic lanes, bike path, shoulders, provision for an eighth traffic lane).
The Pitt River Bridge, which connects the municipalities of Pitt Meadows and Port Coquitlam, is part of the North Fraser Perimeter Road in Vancouver. Constructed within the existing right-of-way, the bridge allows for the free passage of marine vessels without disrupting traffic flow on Highway 7.
The roadway accommodates seven lanes of traffic and a bike path, with provisions for a future eighth traffic lane. The superstructure width in its initial configuration (without the future sidewalk) is 39.0 m (128 ft) to 43.660 m (143 ft) between the exterior stay-cable planes (40.0 m (131 ft) to 44.660 m (146.5 ft) total deck width). The main river crossing features a three-span cable-stayed bridge with a 190 m (623 ft) main span.
The bridge superstructure includes a steel-concrete composite deck supported by three planes of stay cables arranged in a “harp” configuration. It is supported on large-diameter piles anchored in the till, with pile caps at water level. The bridge was completed on time and on budget, and it opened to traffic in the fall of 2009.
