The Port Mann Bridge refers to two old and new bridges in Vancouver, British Columbia, Canada, spanning the Fraser River connecting Surrey on the south bank and Coquitlam on the north bank. The construction of the younger Port Mann Bridge was officially a part of the Port Mann / Highway 1 Improvement Project.
The first-generation Port Mann Bridge was a steel arch bridge that opened in 1964 and closed in 2012; it once carried five lanes of British Columbia Highway 1. The second-generation Port Mann Bridge is a cable-stayed bridge that opened in 2012 to replace another bridge of the same name on the original site. It currently carries ten traffic lanes on Highway 1.
The new Port Mann Bridge took three years to build and cost more than $3 billion. The bridge is the widest in the world and the second longest in North America. This article will detail the current Port Mann Bridge's size.
Description of the Port Mann Bridge Size
The first-generation Port Mann Bridge was in service from June 12, 1964, to November 17, 2012. It was initially four-lane traffic, but the bridge deck was widened and changed to five lanes. It is named after the southern end of the bridge, the Port Mann community in Surrey. The bridge has a total length of 2,093 meters (6,867 feet) and the main span of 366 meters (1,201 feet).
The same day that the old Port Mann Bridge was closed was the day the second-generation Port Mann Bridge opened, followed by the old bridge's demolition. The old bridge was completely demolished in October 2015, but two piers in the Fraser River have been retained to strengthen the river bank and provide habitat for the water creatures. Three eastbound lanes of the new bridge were opened first; two westbound lanes were opened three months later. A total of eight lanes were opened at the end of 2012. The remaining two lanes of the new bridge were put into service in the summer of 2015.
Dimensions of the Current Port Mann Bridge
The current Port Mann Bridge is 2,020 meters (6,630 feet) long (including the approach road), with a main span of 470 meters (1,540 feet) and a deck width of 65 meters (213 feet); its two bridge towers measures 163 meters (535 feet) high. When it opened, it replaced the Sydney Harbour Bridge as the world's widest long-span bridge in the Guinness Book of World Records until the San Francisco-Oakland Bay Bridge replaced it in September 2013. There is a navigable channel with a distance of 42 meters (138 feet) between the water surface and the bridge deck.

The bridge is one of the most charming and elegant bridge designs in Metro Vancouver and one of the busiest, with more than 120,000 vehicles a day, many of them container trucks. Such a comprehensive and long ten-lane also means that maintenance and repair works are not easy. Three weeks after the new bridge opened, serious problems were revealed; large ice balls fell from the suspension cables, hitting passing drivers and vehicles. If the cold storm strikes again, it cannot be ruled out that ice falling from the cables of the bridge may cause major traffic problems.
