    New 10-lane bridge to replace Port Mann

    By Kelly Sinoski, Vancouver Sun
    February 4, 2009

    METRO VANCOUVER — The provincial government has scrapped its plan to twin the Port Mann Bridge in favour of building a new 10-lane crossing over the Fraser River, at a cost of $3.3 billion.

    Premier Gordon Campbell said the new bridge, which will be built to accommodate rapid bus service, expanded cycling and pedestrian lanes and a possible light rail line, will ease congestion clogging the crossing and commuter delays by about one-third.

    The project design calls for two lanes each way to be reserved for local commuters heading south of the Fraser or to the Tri-Cities, as about 40 per cent of the bridge’s traffic never goes past Surrey or Coquitlam, Campbell said.

    Public transit users using the new bridge are expected to be able to get from Langley to a SkyTrain station in Burnaby in 23 minutes.

    But those driving will have to pay for it. Set to open in 2013, the new bridge will be financed primarily by tolls, which will start at $3 each way for all commuters, with concessions for truckers, bus and taxi drivers and van-poolers to encourage public transit.

    The tolls, to be in place for 40 years, will rise with inflation but will be capped at 2.5 per cent annually, government officials said.

    “Currently in B.C. we lose about $1.5 billion in our economy every year to congestion,” Campbell said. “A single span will clear up the bottlenecks that have been plaguing commuters for years and years.”

    Transportation Minister Kevin Falcon said the government’s private partners — consortium Connect BC Development Group, a group that features Australian-based Macquarie Group — believed it would be cheaper and save on maintenance costs to build a new bridge.

    “They didn’t want to be pouring money into aging infrastructure,” Falcon said, adding that in 40 years the existing Port Mann Bridge will be older than the Pattullo Bridge is now. “There will be savings over time.”

    The 37-kilometre project includes widening Highway 1, adding two lanes each way on the east side of the bridge and an extra lane in both directions on the west side. The capital cost of the project is about $2.46 billion, but the total cost, including operating and maintenance, is expected to be $3.3 billion.

    Of that, the province is financing $1.15 billion in the form of a repayable loan, which is being matched by bank financing. Its private partner is putting forward its own equity for the remaining $1 billion.

    The government came to the rescue of its private partners with the loan last month after Macquarie, an international toll-road operator and investor, encountered financing difficulty as a result of the global credit crisis.

    Falcon said construction of the new bridge is a historic event for Metro Vancouver, which is expected to add a million residents in the next 20 years, most of them south of the Fraser.

    He noted commuters and truck drivers now have to spend hours in traffic on the bridge, which was built in 1964 and is one of the most important routes for goods traffic to and from Metro Vancouver ports and businesses.

    Paul Landry, president and CEO of the B.C. Trucking Association, said trucks can be delayed up to an hour on the Port Mann. He supported the idea of toll discounts for trucks to encourage them to operate out of peak hours and keep traffic flowing more smoothly.

    Right now, “It’s terrible,” he said. “It’s very tough and it’s not only the delays and the cost of the delays but the uncertainty. If you’re trying to run on any schedule you have to arrange to leave early. If there’s any kind of an incident on either side of the bridge or on the bridge, things grind to a halt.”

    He said the additional lanes on the highway to the bridge will make a huge difference in cutting the congestion, as will the tolls since they will push commuters to use transit more.

    TransLink spokesman Ken Hardie said that due to congestion, no buses now use the bridge. When the new bridge is built, buses will be able to use it for the first time in 20 years.

    Hardie added that rapid bus lanes on the bridge could be converted to light rail in the future.

    Park-and-ride lots will be added in the Fraser Valley and there will be access lanes for buses on and off the freeway from 216th street in Langley to Lougheed Town Centre.

    The project, which will create 8,000 jobs, ties in to provincial and TransLink plans to boost rapid transit and build the Golden Ears and Pitt River bridges and the South Fraser Perimeter Road.

    Campbell said the province has to create a Pacific Gateway, noting that by 2020, anticipated trade from Asia could bring in $76 billion for B.C. and $230 billion for Canada.

    B.C. Chamber of Commerce president John Winter said the new bridge — along with the other infrastructure — will make it easier to live and work in the Tri-Cities, Maple Ridge, Pitt Meadows and south of the Fraser.

    “That’s where the economic growth is going to be,” Winter said. “It’s absolutely imperative that this bridge — and the other bridges — connecting with the ports are improved.

    “If we’re investing all this money in [Deltaport], this is all tied together and inextricably linked to progress.”

    Coquitlam Mayor Richard Stewart and Surrey Mayor Dianne Watts said it makes more sense to build a new bridge than hold up the old one until it has to be rebuilt in 40 years.

    “What do you do with a twinned bridge in 40 years when you have to tear one down and build a replacement for it?” Stewart asked.

    Cecil Damery, president and business agent of Ironworkers Local 97, said the impact of the recent Pattullo Bridge fire and repair underscored the need for a new bridge as a useful backup in case of emergencies.

    He said the plan is financially sound, since it would cost more to maintain and fix the old bridge.

    Damery added he was confident the project will be a boon for his industry.

    “For every construction job, six other jobs are created. It’s a trickle-down effect,” he said.

    Jack Davidson, president of the BC Road Builders and Heavy Construction Association, said the project shows the government is looking toward the future rather than just short-term.

    The province will have to get environmental assessment approval to build the new bridge, but expects that can be fast-tracked, since most of the work was already done for the twinning of the bridge, Transportation Ministry spokesman Dave Crebo said.

    Crebo said the new bridge is expected to have less impact on the environment because it will be a single span. The old bridge won’t be demolished until the new one is completed.

    NDP MLA Bruce Ralston criticized the government for re-negotiating a deal with its private partners, since other bidders who applied to twin the bridge wouldn’t have had the same opportunity.

    He said the government eight months ago said it would cost $1.6 million to twin the bridge and is now quoting $2.5 billion for the new plan.

    “The minister and premier say this is a way to save costs,” he said. “Table the contract, open it up. How’s it going to escalate over time? We were led to believe they were twinning the bridge. It seems this was negotiated after the contract was awarded.”

    And here is the New Cape Horn Interchange model. The before and after here is amazing. The original Cape Horn was always one of the worst designed interchanges in the world, which is terrible since it essentially is the heart of our entire east/west road network (with also north/south movement between the eastern burbs)



    Again, look at how many arteries are able to interact with so little land, compared to equally important interchanges in American cites. Hence why it reminds me more of an Asian design. Good to see.

    I'm very impressed by the Campbell government's willingness to invest in infrastructure.

    Its worth noting that much of Vancouver's "transit community" is up in arms about this.

    Then again, these are the same people that opposed the Canada Line on the grounds it moves faster than 10km/h, putting it firmly in the same camp as Ronald Reagan and Lincoln Navigators.

  4. Default New Port Mann Bridge-something like Boston's Bunker Hill Bridge...

    O-D and everyone: Interesting info on BC constructing a new bridge instead of improving an older 60s-built bridge here-it reminds me somewhat of Boston's Bunker Hill Bridge that was constructed over the Charles River as part of the Big Dig project-a boondoggle that had delays and cost overruns galore.

    Hard decisions are being made here-by constructing a expensive new bridge instead of renovating older infrastructure. I noticed that transit advocates are protesting this-and can this new bridge either be built with or carry a future Skytrain line?

    As infrastructure gets older sometimes a new bridge is the way to go-like building a entirely new part of the San Francisco-Oakland Bay Bridge(the East Bay section) or what is being considered by the NY Thruway for the Tappan Zee Bridge over the Hudson River Downstate-a extensive renovation of the existing bridge or an entirely new bridge which would include a Metro-North Commuter Railroad line between Westchester and Rockland Counties,NY as good examples of this.

    I noticed that tolls would fund this major project-a necessary evil here.
    I am all for transportation improvments in most any way but the big question can we AFFORD the major cost of new construction?

    -Thoughts and opinion from LI MIKE-

    In this case the reasoning is that since the public private partnership grants the private operator a 35 year operating and maintenance contract, when the private operator hands the infrastructure back to the Province in 35 years, the old bridge will be 75 years - basically at the end of its useful lifespan - and that means that the whole "twinning" exercise will have to be repeated - to replace the older span. This provides a "savings" at the end of the 35 years by not having to replace the older span at that time.

    The estimated costs of maintenance on the old bridge are $180 million.
    The estimated increase in the cost of the new bridge to change it from 5 lanes to 10 lanes is $380 million.
    The cost of a new 5 lane bridge in 35 years to replace the old bridge would probably be $1 billion (comparable to the original estimate for the original 5 lane concept).

    News reports say that an LRT line can be underslung under the bridge deck rather than having to remove the HOV lane to do so.

    Note that the new bridge is divided into collector and express lanes - in that respect, it will function as a through routed expressway bridge as well as a collector lane / arterial road / local traffic bridge. Much of the traffic on the bridge is local traffic between Surrey and Coquitlam that if forced to use the freeway because there is no local arterial road bridge across the river.

    The naysayers are primarily in the City of Vancouver and the City of Burnaby who do not want commuter traffic routing through residential areas - essentially a city vs suburbs argument - even though only something like 20% of the bridge traffic even goes to downtown Vancouver.

    The following figure is an excerpt from a 2004 TransLink report on travel characteristics of Highway 1 traffic:

    Though in both those cases, the existing bridges are ugly-duckling cantilever trusses, whereas I can't see a lot of people regarding Port Mann's bowstring arch as expendably unsightly. (Expendably obsolete is another matter.)

    The Loma Priada (sp?) quake in 1989 sealed the fate of the east spans of the Bay Bridge.
    Asthetics don't factor into the equation. Some people have been commenting - another cable stayed bridge? [i.e. Alex Fraser, SkyBridge, North Arm Bridge, Golden Ears Bridge, Pitt River Bridge]

    Well, they do, sort of--after all, there are reasons why all the postcard views have focussed upon the west-bridge suspension spans rather than the east-bridge cantilever truss. It was *always* the ugly duckling.

    Even if Loma Prieta "sealed the fate", it also provided a providential alibi for addressing an aesthetic defect, much as it did for the demolition of the Embarcadero Freeway...

    Apparently the footings of the cantilevered span of the Bay Bridge weren't piled down properly, so even if they wanted to, it couldn't be earthquake-proofed.

    Note the "asthetics don't factor" comment related to the Port Mann bridge versus its cable-stayed replacement (the comment is oddly truncated as quoted).

    I know; I was just stating how they factored more with the East Bay Bridge, quake or no quake, structural issues or no structural issues. (You seemed to imply that they did not factor at all *there*, either.)

    The worst that can be said about Port Mann is that even its bowstring has a certain 60s superhighway blandness to it. (Well, I guess just like a cable-stayed replacement has a certain modern-day superhighway blandness to it.)

    Come to think of it--though our lack of similarly wide-spannable waterways may be a factor--I find it interesting that the cable-stayed phenomenon has yet to hit Ontario. (Correct me if I'm wrong.)

  12. Default

    Maybe there'll be a cable-stayed in Windsor?

    For the Bay Bridge, I think I recall Arnie threatening to scale back the landmark design to a viaduct style bridge because of ballooning costs. The self-anchored suspension design they chose for the Bay Bridge was definitely chosen because of its uniqueness.

    Vancouver is digging tunnels and throwing up bridges like it's nobody's business. This is their 1962-1977 moment.
