Facts & Trivia

The Port Mann/Highway 1 Improvement Project includes construction of a new 10-lane Port Mann Bridge, widening the highway, upgrading interchanges and improving access and safety on Highway 1. The project spans a distance of approximately 37 kilometres from the McGill Street Interchange in Vancouver to 216 Street in Langley.


  • The new bridge will be an iconic structure – the largest and longest main span river crossing in Western Canada; the second longest (by mere metres) in North America and the 29th longest in the world.
  • The new bridge will be 2,020 metres long - you could fit 34 hockey rinks along the bridge and still have space to hold the Stanley Cup Victory Parade.
  • The new bridge will have three main components:
    • A cable-stayed main bridge (between the end of the cables) across the Fraser river will be 850 meters long (470 metres long between the two towers), and have 288 cables
    • A south approach (Surrey side), which will be 360 meters long
    • A north approach (Coquitlam side), which will be 820 meters long
  • The towers will stand approximately 75m above deck level, with a total height of about 163m from the top of their footing - that's taller than the Sheraton Wall Centre Hotel.
  • The bridge will have 42 metres of navigational clearance above high water level (same length and clearance as existing).
  • The new bridge is 65 metres wide, including 50 metres of roadway (including shoulders), five metre wide multi-use path, with three metres of clearance for pedestrians and cyclists, and 10 metre gap/median where pylons should support the two bridge decks.
  • The bridge will have 10 lanes (five in each direction). Initially opening with eight lanes (four in each direction) the additional two lanes will be completed once portions of the old bridge have been removed.
  • The main span is supported by 288 cables, which if stretched end to end, would cover about 45 kilometres.  
  • Foundations for the new bridge required use of the largest capacity piles (up to 5000 tonnes capacity) in Canada.
  • Compared to the Alex Fraser Bridge, the new Port Mann Bridge is five metres longer and 25 feet taller.


  • 1,158 pre-cast segments in the approach spans
  • 25,000 tonnes of asphalt used for new bridge deck
  • 116 steel composite segments in the cable‐stay span

  • 28,000 tonnes of rebar and 13,000 tonnes of structural steel
  • 37 kilometers of onshore Highway 1 widening
  • 3.1 million m3 of earthworks
  • 30 new, 6 rehabilitated structures
  • 100,000 m2 of retaining walls
  • 8,000 person years of employment
  • New 10 lane, 850 m cable-stayed bridge on the Fraser River Crossing
  • 12,000 tonnes of structural steel
  • 157,000 m3 of concrete
  • 1170 m of approaches
  • 288 cables, 251 piles, 108 caisons
  • 2 pylon towers, each 158 m high
