The Port Mann Bridge is a steel tied arch bridge that spans the Fraser River connecting Coquitlam to Surrey in British Columbia near Vancouver. The bridge consists 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 Port Mann is Template:M to ft, including approach spans. The main span is: Template:M to ft plus the two Template:M to ft spans on either side.[1]. Current volume on the bridge is 127,000 trips per day.[2] Approximately eight percent of the traffic on the Port Mann bridge is truck traffic.[3] The bridge is the longest arch bridge in Canada and 15th longest in the world.

History

The Port Mann Bridge opened on June 12, 1964, originally carrying four lanes. At the time of construction, it was the most expensive piece of highway in Canada. The first "civilian" to drive across the bridge was CKNW reporter Marke Raines. He was not authorized to cross, so he drove quickly.[4] In 2001 a HOV lane eastbound was added by moving the centre divider and by cantilevering the bridge deck outwards.[5]

Widest Bridge in the World

At 65 meters wide, the new Port Mann Bridge will hold the title of being the widest long span bridge of any type in the world. [6] The current record is held by the Sydney Harbour bridge at 49 meters wide.[7]

On January 31, 2006 the British Columbia Ministry of Transportation introduced the Gateway Program as a means to address growing congestion.[8] The project originally envisioned twinning the Port Mann Bridge by building a second bridge adjacent to it.[8]

The PMH1 project adds another HOV lane, provides cycling access and reintroduces bus service to the Port Mann Bridge for the first time in over 20 years. A new bus rapid transit service will be operated within the HOV lanes along Highway 1 from Langley to Burnaby.[9]

Rather than twin the bridge, the government unveiled plans on February 4, 2009 to replace the bridge with a new 10-lane bridge; the bridge will be tolled, electronically, approximately $3 each way. The estimated cost of construction is $2.46 billion (This also includes the cost of the Highway 1 upgrade, a total of 37 km). The total cost including operation and maintenance is expected to be $3.3 billion. When the new bridge is completed, the existing bridge, which will be more than 45 years old, will be taken down.[10]

The project was intended to be funded by using the Public-private partnership funding format, and Connect B.C. Development Group was chosen as the preferred developer. The Connect B.C. Group includes the Macquarie Group, Transtoll Inc., Peter Kiewit Sons Co. and Flatiron Constructors.[11] Although a memorandum of understanding had been signed by the Province, final terms could not be agreed. Consequently, the Province will be funding the entire cost of replacement.[12]

In total the new bridge will be 2.2 km long, 50m wide carrying 10 lanes, and have a 42m clearance above high water level (same length and clearance as existing). The towers will be approximately 75m tall above deck level (total height approx 163m from top of footing). The main span (between the towers) will be 470 meters long, which will be the second longest cable-stayed span in the Western Hemisphere. The main bridge (between the end of the cables) will have a length of 850 meters with two towers and 288 cables.

Opposition to Original Twinning Plan

A number of groups have lobbied to improve mass transit rather than build a new bridge. Opponents to the expansion include the Municipality of Burnaby,[13] some urban planners,[14], and the Sightline Institute[15].

Opponents argue that increasing the highway capacity will only relieve congestion for a few years before increased traffic congests the area again,[16] and would encourage suburban sprawl. The Livable Region Coalition has urged the Minister of Transportation, Kevin Falcon, to consider rapid transit lines and improved bus routes instead of building the new bridge.[17]

The David Suzuki Foundation claims the plan violates the goals of Metro Vancouver's Livable Region Strategic Plan.[18]
