West Seattle Bridge Updates

The sudden safety closure of the West Seattle “High-Rise” Bridge in March 2020 has been a major challenge for Seattle and Washington State. Even though the West Seattle Bridge is not in Seattle’s District 4, Councilmember Alex Pedersen provides periodic updates on the closure, stabilization, repairs, and other issues impacting the bridge because he was appointed to Chair the City Council’s Transportation & Utilities Committee in January 2020. The West Seattle Bridge is an infrastructure asset vital not only to the 100,000 people of West Seattle but also to the entire region, especially as it impacts the economic engine that is the Port of Seattle. After successfully stabilizing the bridge in 2020, the ultimate goal was to complete substantial repairs (“rehab”) in time to restore access to the West Seattle “high bridge” mid-2022 (which became September 18, 2022). When the high bridge was closed for repairs, the Spokane Street Swing Bridge (West Seattle “low bridge”) became the “workhorse” bridge that provided limited access, and we have scheduled upgrades for that bridge, too. Alternate routes made available can be found on the website of our Seattle Department of Transportation (SDOT).

September 16, 2022 update: West Seattle Bridge Ready to Open September 18, 2022!

“I share the relief of 100,000 neighbors that we are finally reopening this vital regional bridge that connects all of us,” said Councilmember Alex Pedersen, Chair of Seattle’s Transportation Committee. “This long-awaited re-opening is less of a celebration and more of an expression of gratitude to the engineers and construction workers who carefully repaired this vital regional bridge to make it strong and safe again.

“While we are all grateful to see the bridge repaired and re-opened after two and a half years of repairs, I believe this must serve as a wake-up call to reprioritize and reinvest in all of Seattle’s aging bridges.  In a growing city carved by waterways, forged by the harsh experience of the West Seattle Bridge closure, and armed with the audit we obtained to assess our aging infrastructure, I look forward to new SDOT leadership prioritizing proactive improvements to Seattle’s bridges, because the people and businesses of Seattle cannot afford another bridge closure.”

Councilmembers Herbold, Pedersen React to the Announced Reopening of the West Seattle Bridge in September

SEATTLE – Councilmembers Alex Pedersen (District 4, Northeast Seattle) and Lisa Herbold (District 1, West Seattle & South Park) reacted to the announcement from SDOT today that the West Seattle Bridge is scheduled to reopen in three months, as soon as the week of September 12, 2022. 

“We know that all of West Seattle, South Park, and Georgetown have had the bridge reopening top of mind since it closed. I am still holding out hope for a summer re-opening, but I appreciate SDOT’s announcement today; it lets us know that we’re close – just three months away,” said Councilmember Lisa Herbold

“I’m relieved we finally have a safe and certain reopening date, and I know it’s disappointing to many that the concrete strike delays could not be overcome. I urge the project managers to consider extra shifts so the bridge re-opens before schools re-open,” said Councilmember Alex PedersenChair of the Transportation and Seattle Public Utilities Committee. “While I look forward to re-opening this vital regional bridge after more than two years of repairs, this must also be a wake-up call to reprioritize and reinvest in all our aging bridges.  In a growing city carved by waterways, forged by the harsh experience of the West Seattle Bridge closure, and armed with the audit of our aging bridges that I obtained for SDOT, all leaders should prioritize the proactive fixing of Seattle’s bridges and so we’ll look to the Executive’s budget proposal this Fall, because the people and businesses of Seattle cannot afford another bridge closure.” 

The West Seattle Bridge was promptly and unexpectedly closed in 2020 due to safety concerns, as inspectors saw cracks growing rapidly in the 40-year-old bridge. Since then, the City of Seattle has been working to remediate the closure, and ultimately decided to repair the bridge in lieu of replacing it. Repair work has been underway for two years but was delayed due to the recent, regional concrete strike. 

As part of their announcement today, the Seattle Department of Transportation (SDOT) released a tentative schedule for the remaining work, while simultaneously cautioning that large-scale projects like the repair of the West Seattle Bridge are complex and additional delays are still possible. Regardless, SDOT has pledged to continue transparently sharing information about the project schedule going forward.

November 29, 2021: “Notice to Proceed” for General Contractor

As announced by Mayor Durkan and SDOT today, SDOT and its selected construction contractor Kraemer North America agreed on a construction schedule that will complete repairs by mid-2022 (pending any unforeseen issues due to extreme weather events, supply chain problems, worker shortages, or other unexpected conditions).

The final phase of repairs includes:

  • Injecting epoxy into the cracks to seal them and prevent corrosion.
  • Wrapping parts of the structure with carbon fiber-reinforced polymer for durability to strengthen the bridge, similar to putting a cast on a broken bone.
  • Installing more tight steel cables called post-tensioning strands through the entire bridge. These strands reinforce the concrete, much like the bridge’s skeleton.

For 20 months, District 1 residents and businesses have been suffering, with longer commutes to work, medical appointments, school and activities, less time spent with loved ones, and difficulty accessing necessary business supplies,” said Seattle City Councilmember Lisa Herbold. “For residents in the southern neighborhoods, including South Park, they’ve had increased traffic safety impacts. Starting the repair process is a huge step for District 1; completing the repair by the scheduled date of mid-2022 is critical. I will be in close coordination with SDOT as this work moves toward successful, on-time completion of the repair.”

The emergency stabilization of the West Seattle Bridge that’s already occurred gives these full repairs a head start and we all look forward to their completion next summer to restore this vital transportation link for tens of thousands of Seattle residents,” said Seattle City Councilmember Alex Pedersen, Chair of the Council’s Transportation Committee. “I’ll continue to be a champion for investing in our infrastructure and strengthening Seattle’s bridges and I am pleased the final phase of these repairs are underway so everyone can use the West Seattle Bridge again as soon as possible.”

“Our teams have been preparing for months to come back to the high bridge to complete this work to get vehicles back on the bridge. Our crews are familiar with the bridge from our work on stabilization and excited to get going,” said Kraemer North America Project Manager Adam Dour. “We’ll also be working to strengthen the Spokane St Swing Bridge as part of this contract, and we’ve worked closely with SDOT to ensure that our schedule prioritizes the reopening of the bridge as quickly as possible.”

June 28, 2021 Update: Federal Grant Awarded

As reported in the Seattle Times, there is good news for Seattle from our federal government with the United States Department of Transportation awarding a grant to help our efforts to restore the West Seattle Bridge. While the dollar amount was less than our request, it is remarkable to have received any of these competitive federal funds. We are grateful to U.S. DOT Secretary Pete Buttigieg and to our congressional delegation including Representatives Jayapal and Smith and Senators Cantwell and Murray. I’d also like thank our own Seattle Department of Transportation for seizing this and all opportunities to cobble together money to restore the West Seattle High Bridge and to strengthen the lower bridge that has been carrying much of the burden. SDOT submitted an award-winning application which included a letter of support signed by this City Council. I’m hopeful SDOT will put this $11 million to good use for the $175 million restoration project, which includes funding from the City, the Puget Sound Regional Council, and other sources.  For SDOT’s blog post on this award of funding, CLICK HERE.

March 15, 2021 Update:

I asked the Seattle Department of Transportation (SDOT) to participate in my Committee on March 17, 2021 to provide another presentation on the West Seattle Bridge. The purpose is to update the public and my Council colleagues on SDOT’s progress to restore the West Seattle High Bridge — and to strengthen the “low-level” bridge (Spokane Street Swing Bridge) which has had to carry a bigger burden during this infrastructure emergency. This update is timely due to SDOT completing 30% of the design for the restoration, a milestone which enables them to firm up total costs and seek competitive bids from general contactors to complete the work by the 3rd quarter of 2022. While the revised total cost estimate is $175 million, much of that total includes the costs of the initial emergency stabilization efforts (which helps with the ultimate restoration work) and the costs of establishing/improving alternative routes (“Reconnect West Seattle”). The actual construction costs for restoration of the West Seattle High Bridge is estimated to be $60 million (out of the $175 million). To cover the total cost, we have set-aside up to $100 million of city government resources, but it would be ideal to secure funds from other sources — which we have been pursuing aggressively: regional (approx $15 million from Puget Sound Regional Council), State (ideally $25 million from the 2021 legislative sessions), and Federal sources (a $20 million “INFRA” grant). Moreover, a portion of the renewed and revamped Seattle Transportation Benefit District (STBD) will assist during at least the next year.

January 1, 2021 Update:

To protect the physical integrity of the still-open lower bridge (underneath the closed West Seattle high bridge) and “to keep the Low Bridge clear for emergency vehicles – as well as transit and heavy freight – we’re saying, ‘don’t go low.’ Instead, please use alternate routes for those traveling to and from West Seattle by car to avoid a $75 citation.” For the SDOT Blog post, CLICK HERE.

November 19, 2020 Update:

Today Mayor Durkan announced her decision to REPAIR the West Seattle Bridge, which I support after careful consideration. Here is my statement:

After consulting technical experts, Seattle residents, local businesses, and the Port of Seattle, I want to thank our Mayor for her careful and thorough consideration of how best to move forward safely and effectively so we can quickly restore this vital infrastructure,” said Seattle City Councilmember Alex Pedersen, appointed earlier this year to chair the Council’s Transportation Committee.  

After studying the various choices, I agree with Mayor Jenny Durkan that immediate repair of the bridge is the best choice so we can quickly and safely restore mobility to our region’s bridge network. Repairing the bridge now still keeps open the long-term solution to plan and fund a methodical replacement in the future and to coordinate with increased transit options. I believe the cracking and closure of the West Seattle Bridge must be a wake-up call to take better care of all our aging bridges with more investment in maintenance to keep transit and freight moving throughout a city defined by its waterways and ravines. After being appointed to Chair our City’s Transportation Committee earlier this year, I remain committed to work with Mayor Durkan, our Seattle Department of Transportation, our Port of Seattle, the rest of the City Council, and Seattle residents to make sure we honor this commitment to our bridge infrastructure and get this done.”

November 9, 2020 Update:

Councilmembers Alex Pedersen (as Chair for the Transportation Committee) and Lisa Herbold (District 1, West Seattle) asked the Seattle Department of Transportation (SDOT) to provide the City Council and the public with a formal update on the West Seattle Bridge at a “Council Briefing” today.

  • For SDOT’s November 9, 2020 presentation, CLICK HERE.
  • For the Cost-Benefit Analysis (CBA) of various options for repair and replacement, CLICK HERE.

Now that the West Seattle high bridge is stabilized, the key question is whether to repair or replace it and we have developed several good options for moving forward to restore that vital infrastructure for Seattle residents and our regional economy. I know the Mayor is prudently consulting engineers, stakeholders, and funders so that she can make a strategic decision that prioritizes safety and reliability for our city and our region. I believe this crisis should be a wake up call to our city that we need to do much more to fund the maintenance of our aging bridges, a challenge further demonstrated by the recent audit of Seattle’s bridges.

September 16, 2020 Update:

After the sudden closure of the West Seattle Bridge in March 2020, Councilmember Pedersen asked the City Auditor to provide an independent assessment of all Seattle Bridges. That report confirmed that Seattle has been under-investing in its bridges and made several recommendations for improvement.

Councilmembers Herbold and Pedersen Respond to West Seattle Bridge Remaining Closed through 2021

4/15/2020 STATEMENT: SEATTLE – Councilmember Lisa Herbold (District 1 – West Seattle/South Park) and Councilmember Alex Pedersen (District 4 – Northeast Seattle and Chair of Transportation & Utilities Committee) issued the following statement regarding the ongoing and extended closure of the West Seattle Bridge:

“Today we learned from the Seattle Department of Transportation (SDOT) that, while the rate of cracking of concrete under the West Seattle Bridge has slowed, new cracking continues even with no vehicles.  Unfortunately, SDOT now estimates the bridge cannot be made safe for traffic for at least the next 21 months (through the end of 2021). Safety will continue to be the top priority during this infrastructure emergency. SDOT is developing plans to shore up the bridge in advance of the likely extensive repairs. SDOT believes, however, that repairs would extend the life of the bridge for only 10 years.

“The impact of this long-term closure on West Seattle cannot be overstated. We will need additional work to manage traffic and mobility for residents. Ensuring access to emergency services and transit will be critical as well. What we are doing now to provide alternate routes will not be sufficient once traffic resumes normal levels.

“We look forward to working with our State and federal governments to identify the funding for both the repairs and the eventual replacement of the bridge, including an expected stimulus package for infrastructure from Congress. This situation also reinforces the importance of renewing the Seattle Transportation Benefit District to provide additional bus service.

“It’s good that SDOT is creating a technical advisory panel to leverage engineering expertise.  The City Council’s Transportation & Utilities Committee will require timely updates from both SDOT and the technical advisory panel.  We will also pursue Legislative Department participation on the technical advisory panel to increase oversight of the complex solutions.”

“When I learned about this issue today, I immediately supported the Mayor’s decision to temporarily close the West Seattle Bridge because safety should be our top priority,” said Councilmember Alex Pedersen who chairs the City Council’s Transportation Committee.  “As we provide safe travel alternatives for residents, first responders, and public transit, I look forward to hearing not only an analysis from structural engineers but also next steps, including a realistic timeline for solutions from our Seattle Department of Transportation (SDOT).”

“As Chair of the Transportation Committee, I’d like to schedule a public briefing in the future so we can all hear the latest structural reports on all Seattle bridges and the plans for repairs and upgrades.  Strategic infrastructure projects that increase safety, move freight, and get thousands of people to their jobs will be vital as we eventually lift ourselves out of the public health and economic crisis.”  

March 23, 2020FULL PRESS RELEASE (from SDOT):

Following Accelerated Growth of Concrete Cracks in West Seattle High Rise Bridge, SDOT to Close Structure This Evening for Assessment

Spokane Street “Low Bridge” to Remain Open Only to Transit, Freight, and Emergency Vehicles

Seattle – Out of an abundance of caution, the Seattle Department of Transportation (SDOT) announced today that it will close the West Seattle High-Rise Bridge effective 7:00 PM tonight (March 23, 2020) to all traffic due to accelerated concrete cracking that was observed during a regular bridge inspection. A comprehensive assessment has already begun with a team of experts to determine the extent of the cracking and put together a plan for a near-term repair. The bridge closure will begin at 7 PM tonight will remain closed until further notice.

Buses, freight and emergency vehicles will be moved to Spokane Street Bridge, which is also called the “low bridge,” and motorists should use the First Ave or South Park bridges.

“Even in the midst of a pandemic, the Seattle Department of Transportation has been closely monitoring our critical infrastructure. Last night, our engineers identified safety risks in our West Seattle high rise bridge and are now taking swift action to protect the public by removing traffic from the bridge while next steps are assessed,” said Mayor Jenny Durkan. “Transit, freight and first responders will continue to have access to the Spokane Street bridge to ensure access to and from West Seattle. To the residents and businesses of West Seattle: I want to thank everyone for their flexibility and patience during this challenging time in Seattle’s history. It is a top priority to ensure safety and access to goods and transit, and we will be working as quickly as we can resolve this.”

“We’ve kept a watchful eye on the West Seattle Bridge for years. Recently, a series of closely monitored cracks have grown faster than our team of experts had anticipated. Our engineers saw this acceleration as a clear warning sign that closer inspection is necessary, and complete closure is required to maintain safety as our top priority. As we close the bridge today, we will scale and accelerate a process already underway to determine next steps. Above all else, as the Mayor has made clear, we will make sure our first responders have quick and safe access to and from West Seattle,” SDOT Director Sam Zimbabwe said.

“As a West Seattle resident and a citywide public official representing all Seattleites, I believe this is the right decision for the safety of West Seattle bridge users, and the long range transportation demands of my constituents,” said Council President M. Lorena Gonzalez (Pos. 9 – Citywide).  “I stand ready to work with Mayor Durkan, Director Zimbabwe, Councilmember Herbold and Chair Pedersen, to address the short-term and long-term impact of this bridge closure.  Keeping people safe is critically important and this closure prioritized the health and safety of the over 100,000 people who use the West Seattle Bridge every day.”

“I support the Mayor’s decision to temporarily close the West Seattle Bridge because safety should be our top priority,” said Councilmember Alex Pedersen who chairs the City Council’s Transportation Committee.  “As we provide safe travel alternatives for residents and public transit, I look forward to hearing not only an analysis from structural engineers but also next steps, including a realistic timeline for solutions from our Seattle Department of Transportation (SDOT).”

At 7PM, all public and private vehicles will be prohibited from crossing the high-rise span of the bridge between I-5 and Fauntleroy Way SW. SDOT is putting signs in place to guide people through the new route. Prohibiting people and vehicles from the structure reduces the load weight and is necessary for public safety.

While the problems have accelerated at a rapid and unanticipated rate, this challenge did not appear out of the blue. The West Settle Bridge was originally designed for three lanes of travel in each direction. As Seattle grew, the bridge grew to three westbound lanes and four eastbound. This added traffic, combined with the significant increase in size and weight of commercial vehicles (including buses), has only compounded the long-term maintenance challenges posed by the West Seattle Bridge. Further, 80 percent of the bridge load is dead load, meaning deterioration is possible even when all traffic is removed. 

In 2019, however, the Federal load rating for this type of bridge changed and the Seattle Department of Transportation assembled a team of engineers and experts from the public and private sectors to begin actively assessing the extent and growth of bridge cracking, create safety recommendations, and a short-term repair plan.  As a component of that review, SDOT has been regularly inspecting concrete cracks in the West Seattle Bridge. During the latest inspection, an SDOT engineer found known cracks in the concrete had worsened at a rate SDOT and the outside specialists found unacceptable.

The City is working with King County Metro and regional transportation, life-safety, and maritime partners today to jointly develop a comprehensive traffic control plan to keep people and goods moving. This plan will include bus reroutes, general traffic detours to alternative streets and bridges, and a street-by-street approach to increase the capacity of detour routes to better carry the traffic using the high-rise bridge today.

The Seattle Police Department, Seattle Fire Department, and medical first responders are aware of the closure and planning detours. SDOT’s traffic control plan will use streets that accommodate the emergency response network to connect communities to hospitals as they are today.

King County Metro bus routes that typically travel the West Seattle Bridge include RapidRide C Line, 21 and 21X, 37, 50, 55, 56, 57, 116X, 118X, 119X, 120 and 125. Routes 37 and 125 are not operating during Metro’s temporary reduced schedule, which started March 23. Metro is working to finalize bus reroutes using the Spokane Street lower bridge and surface streets in SODO, and identify whether any bus stops might not be served as a result of the reroutes. Metro customer information staff plan to post service advisories online later Monday.
