City and transportation department officials from Portland and Vancouver got a first look at the possible designs for the proposed Interstate 5 bridge replacement Thursday morning.

The project is the regionโ€™s second attempt at replacing the Interstate 5 Bridge over the Columbia Riverโ€”a major thoroughfare for commuters and freight trucks. It comes on the heels of the Columbia River Crossing (CRC) project, which failed in 2014 after Washington and Oregon legislators were unable to agree on a funding plan.

In 2019, Oregon Governor Kate Brown and Washington Governor Jay Inslee revived the bridge replacement project, citing the need to address the seismic instability of the bridge, as well as improve traffic flow. The project now has a new name: the Interstate Bridge Replacement (IBR).

Now, after almost a year of discussing the issues the project needs to address, like traffic congestion and โ€œsubstandard bicycle and pedestrian facilities,โ€ the projectโ€™s oversight committeeโ€”made up of Portland and Vancouver city officials, public transit representatives, and transportation department leadersโ€”are moving onto developing solutions, starting with selecting the bridge design.

The three proposed interstate bridge designs include the former CRC designโ€”two five-lane bridges side-by-side with dedicated public transit and pedestrian and bicycle pathways underneath. The committee was also presented with a variation of the CRC design with a different onramp configuration and a single bridge option that stacks the north and southbound lanes on top of each other, flanked on either side by the transit lanes and a pedestrian and bicycle pathway. The bridge also has 10 possible public transit configurations, ranging from high-capacity light-rail, rapid bus service, and a combination of both.

According to IBR Program Manager Greg Johnson, the three design options provide the framework for the project to meet its goals of reducing travel times, increase the number of people using public transit, reduce crashes on I-5, and increase the bridgeโ€™s resilience to a major earthquake.

The IBR program leaders are asking the steering committee to select one of the design options by early 2022. Committee members on both sides of the state lines are skeptical of that timeline, mostly due to the time it will take for each agency to individually assess the options, ask follow-up questions about the projectโ€™s impacts, bring their viewpoints to the committee, and reach a consensus.

โ€œIโ€™m on board, but this still is a pretty fast timeline that Iโ€™m concerned with,โ€ said Steve Witter, TriMetโ€™s director of engineering and construction. โ€œWe donโ€™t need to be in a rush to make a bad decision.โ€

Metro President Lynn Peterson requested more detail from the IBR team on how the proposed tolling of the bridge and an increase in public transit options would impact vehicle demand.

Portland City Commissioner Jo Ann Hardesty, who oversees the Portland Bureau of Transportation, emphasized how the bridge could impact the regionโ€™s climate goals.

โ€œThis project has to be part of the solution to the problem that we have on I-5, but it needs to demonstrate how it wonโ€™t contribute to more 124 degree days like we experienced just this last summer in the Lents neighborhood in Portland,โ€ Hardesty said. โ€œIt needs to demonstrate how it wonโ€™t contribute to elevated rates of asthma and hospitalization for Black and brown Portlanders which normally are the recipients of the negative outcomes of freeway activity.โ€

โ€œIโ€™m happy moving forward,โ€ Hardesty said, โ€œIโ€™m just saying donโ€™t forget these critical components as we continue.โ€

After deciding on a design early next year, the committeeโ€™s recommendation, along with input from various other public surveys and community groups, will be presented to the bi-state legislative committee overseeing the bridge replacement. That group of Oregon and Washington legislators will be responsible for ultimately selecting the bridge design and moving the project into the environmental assessment phase, which evaluates how the project will impact the surrounding area. The IBR project aims to break ground on the bridge in 2025.

Future IBR meetings and opportunities for public comment on the project can be found on the IBR website.

  1. It’s no surprise that ODOT chumps are doubling-down on their absurd double-deck bridge design. The first bridge designs 2004-2008 were sensible, simple single-deck like the Glen Jackson on I-205. Then an African American was elected President and CRC Commission leaders Wsdot and ODOT took Mitch McConnell’s vow to “not cooperate with Obama” as “consent” to waste millions on double-deck bridge designs they know should NOT be built. Of the 4 bridge designs from 2011-2013, the first was “peer reviewed” and judged “structurally unsound,” the last design dubbed “Like balancing a bowling ball on a golf tee.” Putting the transit corridor on a lower deck is a crime. Put it on the same level and it becomes and emergency access corridor! “We don’t need no stinking emergency access corridor,” grunt ODOT trolls. ODOT director Kris Strickler and Metro Council President Lynn Peterson should be charged with CRIMINAL violations of the planning process. These line & dot junk maps are meant to mislead the public. So far the project cost is $250 million and the design is junk.

  2. The LPA (locally preferred alternative) access to Hayden Island is a death trap. The new central underpass means the exit ramps are blindly steep as they lead to ‘T’ stops. In the southbound direction, motorists who can’t or don’t stop or do stop but someone behind doesn’t, plunges motorists in the water; an unacceptably high rating for rear-end accident hazard in both directions that should be stricken from the plan, but just fine with ODOT director Kris Strickler (former Wsdot project manager along with Lynn Peterson).

    In 2011, when the first bridge design was made public and peer reviewed as “structurally unsound” – the first thing CRC leader Wsdot did was defer funding to finish ODOT’s Marine Drive interchange, a fine design to construct first to create construction staging access, but now potentially off the table. The Port of Portland needs better access to Marine Drive and the existing stoplight and public crosswalk are terrible.

    The Coast Guard killed the original CRC project in 2013 by announcing it didn’t meet minimum standard river clearance of 125′ – the design first was 90′ and then raised to 116′ after the concern was raised by the Port. So add 10′ to the design and the terrible Hayden Island access design gets more complicated and more expensive. Simpler single-deck met the river clearance, but it’s still off the table even though it was the preferred alternative 2004-2009. Go to the project webpage linked in the article and you’ll find LOUSY maps that clearly demonstrate the project is again criminally mismanaged by nefarious crooks and dimwits who’ll do anything for money like that famous John Lennon song “All you need is money…money money…money is all you need.”
