The Port Mann Bridge is a newly designed 10-lane cable-stayed bridge that opened to traffic in 2012. It is currently the second longest cable-stayed bridge in North America and the widest bridge in the world. The new bridge replaced a steel 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 eight percent of the traffic on the Port Mann bridge was truck traffic.
