Description
The Port Mann Bridge is a 10-lane cable-stayed bridge that opened to traffic in 2012. It is currently the second longest cable-stayed bridge in North America and was the widest bridge in the world until the opening of the new Bay Bridge in California. The new bridge replaced a steel arch bridge that spanned the Fraser River, connecting Coquitlam to Surrey in British Columbia near Vancouver. The old bridge consisted of three spans with an orthotropic deck carrying five lanes of Trans-Canada Highway traffic, with approach spans of three steel plate girders and concrete deck. The total length of the previous Port Mann was 2,093 m (6,867 ft), including approach spans. The main span was 366 m (1,201 ft), plus the two 110 m (360 ft) spans on either side. Volume on the old bridge was 127,000 trips per day.Approximately 8 percent of the traffic on the Port Mann bridge was truck traffic. The previous bridge was the longest arch bridge in Canada and third-longest in the world at the moment of inauguration.
