Project Update on 30% Design
ISSUE
Information regarding the 42nd Ave South Bridge Replacement Project.
BACKGROUND
The 42nd Ave South Bridge is an important arterial that crosses the Duwamish River and connects the
City of Tukwila to surrounding communities and resources. The bridge serves over 10,000 vehicles
daily, as well as pedestrians and cyclists connecting to the Green River Trail, the Tukwila Community
Center, the Tukwila Park & Ride, and the Allentown neighborhood. It was built in 1949 and designed
to last 50 years; it has exceeded its original design life by over 20 years.
In August 2017, the City received the 42nd Ave S Bridge Structural Assessment by TranTech
Engineering LLC, which determined that, "...the existing bridge is both structurally deficient and
functionally obsolete." It also revealed that the bridge has a sufficiency rating of 7.56 out of 100,
which forced the City to implement vehicle load restrictions, reduced speed limits of 15 mph, and
limited passage of one truck at a time - regulations that were implemented to reduce structural
impacts and increase safety until the bridge can be replaced.
The City applied for state funding to replace the bridge in 2017 and 2019 through federally supported
grants programs but was unsuccessful in these requests.
In 2020, the City reached out to state and federal officials, who recommended that the City may be
more successful in future funding requests by moving forward with the design of the 42nd Ave South
Bridge. Therefore, the City put forward a request for qualifications for design. In November 2020, the
City Council approved $1.078 million in funding for a 30% design for the 42nd Ave S Bridge
Replacement. Included in this project is extensive community outreach to the Allentown neighborhood
and other impacted communities, which is just in the beginning phase.
At this point in time, the bridge is not effectively supporting the capacity and load requirements
needed to be efficient, and its poor structural integrity makes it a hazard. If one or more of the
beams were impacted by a large seismic event or vehicle collision, it could cause the bridge to
collapse into the river.
ANALYSIS
The City's goal is to build a new bridge that will support the community for the next 75+ years, as it is
the primary route for the Allentown neighborhood. TranTech Engineering LLC is developing
preliminary designs for the 42nd Ave S Bridge Replacement, which will give the City multiple
design/material options for the bridge replacement. The options will be presented to the City in the

Type, Size, and Location (TS&L) report. The TS&L report options will implement variables such
as increasing weight capacity for vehicles, wider lanes, and improved walkways for pedestrian safety.
The City is working with a community engagement consultant, Envirolssues, who was hired by
TranTech Engineering LLC to facilitate interviews of stakeholders and residents who would utilize the
new structure. The City is currently in the process of embarking on those interviews and the Public
Works Director is scheduling a stakeholder meeting with a small group of Allentown residents in the
coming weeks.
The City is also planning to have a virtual open house in late April to give Allentown residents an
update on the project and gather input regarding the structure. The Department is working with the
design team to disseminate information regarding the 42nd Ave South Bridge Replacement Project
and increase communication strategies with the public.
Continuing updates are being shared through the City's website and the Hazelnut. The 42nd Ave S
Bridge inspection updates were shared through a postcard mailing and a Hazelnut article in July of
2020. The Public Overview attachment provides a summary and schedule of our public outreach
strategy.
FISCAL IMPACT
The 30% design contract with TranTech Engineering LLC for $1,078,487.00 was approved by Council
on November 2, 2020. The 30% design is scheduled to be completed by end of 2021.
The total project cost for the 42nd Ave South Bridge Replacement Project is estimated to be $21.5
million. The Department is actively applying for local, state, and federal grants to supplement the
remaining funding required to finalize the 42nd Ave South Bridge Replacement Project. Recent
applications have included:
1. Washington House Transportation Budget Request — 2021 (Rep. Hackney)
2. 2021 Washington Senate Democratic Caucus Transportation Budget Form (Sen. Hasegawa)
3. Local Bridge Program Grant (formally known as BRAC)
4. Office of Senator Patty Murray Funding Solicitation
5. National League of Cities Budget Request
The City continues to explore other possible funding sources to accelerate the replacement of the
42nd Ave South Bridge. The Department is currently working on applications for the following granting
agencies:
1. Federal grant programs (BUILD grant)
2. State grant programs, including Public Works Board
3. Transportation Improvement Board (TIB)
4. Washington Freight Mobility Strategic Investment Board (FMSIB)
5. Puget Sound Regional Council (PSRC)
6. Transportation, Housing and Urban Development (THUD)

42nd Ave S Bridge Replacement Project
Project Overview
The 42nd Ave S Bridge is an important arterial that
crosses the Duwamish River and connects the City
of Tukwila to surrounding communities and
resources. The bridge, built in 1949, is reaching the
end of its life span and needs to be replaced. In
April 2017, the existing bridge received a
sufficiency rating of 7.56 out of 100 and is
considered Structurally Deficient and Functionally
Obsolete by the Federal Highway Administration.
The City is exploring options for a new bridge
design and will be gathering feedback from the
public on a variety of project features.
What's Happening Now?
Crews are onsite conducting fieldwork activities
that will inform engineers of existing site
conditions so they can begin preparing preliminary
design plans. We have begun engaging
surrounding stakeholders and the public to
identify design options and project opportunities.

42nd Ave S Bridge Replacement Project
Stakeholder Interview Summary
February 12, 2021
Purpose/Goals
The first phase of community engagement for the 42nd Ave S Bridge project is focusing on building relationships with key
stakeholders, establishing local avenues for project communications, and ensuring outreach plans are in alignment with
stakeholder needs. Outreach during this phase includes interviews and briefings with key community stakeholders to gather
initial feedback about the project, potential solutions, decision criteria and tradeoffs and outreach approach.
The goal of the first round of stakeholder interviews is to:
• Build relationships with key stakeholders to facilitate continued coordination through the life of the project and
future coordination with the City of Tukwila on other projects.
• Share initial information about the project need and timeline.
• Provide an opportunity to stakeholders to share their project needs and concerns.
• Gather feedback on local avenues for project communications and engagement and how stakeholders would like
to stay informed throughout the project.
Stakeholders Interviewed
February 1, 2021 - BNSF Intermodal: Johan Hellman, Benjamin Marx, Megan Shea, Cheryl Townlian
February 2, 2021 - Tukwila Community Center: John Dunn
February 5, 2021 - Baker Commodities / Seattle Southside Chamber of Commerce: Mike Bulleri
Stakeholders reached out to but not interviewed
Seattle Southside Chamber of Commerce: Andrea Reay
Green River Trail: Kris Kelly and Matt Austin
Interview Approach
Stakeholders were identified based on their proximity to and reliance on the existing 42nd Ave S bridge, and services
provided to the Allentown neighborhood. Once stakeholders were identified, the community engagement team reached
out by email to schedule times to meet virtually on Zoom. The interviews were staffed by the City of Tukwila Project
Manager, technical team staff, and the community engagement team.
At the interview, the team shared a project overview including project purpose, community engagement and design
schedules, and answered any outstanding questions before jumping into interview questions. Below is a list of interview
questions, shared ahead of meetings, to help guide the conversation. Depending on the stakeholder, not all questions were
asked, and some clarifying questions not listed below were asked.
Interview questions (sent prior to stakeholder interview)
Experience using the bridge
• Before we get started, are there any questions you have about the project that you would like to make sure
we cover?
• What methods of travel do you use that take you over the bridge?
• What has been your experience crossing the bridge?
• What kind of issues, if any, do you and your [membership/students/staff/customers/etc.] experience when
using the bridge?
Future use of the bridge
• What ideas do you have for making the bridge a welcoming gateway into the Tukwila or Allentown
community?
Page 1 of 2

• Keeping in mind federal funding limitations, what do you hope the City of Tukwila prioritizes and considers
when developing design and construction concepts for the bridge?
Engagement
• Due to COVID-19, we are unable to meet with folks in person and hold an in-person open house. As an
alternative we plan to host a virtual presentation (if we can) and an online open house for project neighbors
and bridge users. We're planning to engage businesses, community organizations and other stakeholders via
phone conversations and virtual meetings to share design and construction concepts. Are there other ways
you would suggest the City gather feedback from the community?
• What is the best way for us to keep you and your [business/organization] informed and engaged throughout
the project?
• Are there other specific community groups that you suggest we also talk to?
Conclusion and next steps
• Do you have any remaining questions about the project that we didn't cover?
• Do you have any additional thoughts that you want to make sure we capture?
What We Heard
Current bridge uses
Several project stakeholders identified the 42nd Ave S Bridge as critical infrastructure that supports the transportation
options of the surrounding area. The bridge is a primary corridor into the Allentown neighborhood. For the freight and
industrial community, the bridge is a critical link in the freight network on a local scale and regional scale as goods and
products are shipped and moved cross-country to freight hubs. Baker Commodities and third -party truck companies use the
42nd Ave S Bridge to access the Allentown neighborhood -area when doing business.
Design opportunities
BNSF requests that the new bridge be designed to handle current and future load capacity as well as incorporate the ability
to support double -trailer trucks. Baker Commodities also advocates that the bridge be designed with large trailer trucks in
mind. The Tukwila Community Center viewed the design of the new 42nd Ave S Bridge as an opportunity to create better
cohesion between the community center, the bridge, and the Green River Trail in an effort create a welcoming gateway to
the Allentown neighborhood.
Baker Commodities, BNSF, and the Tukwila Community Center all voiced concern about access during construction since
the bridge closure would directly impact how people travel to and from the area.
Future communication and outreach opportunities
Several stakeholders suggested continuing to plan communications and engagement activities in a virtual setting for the
foreseeable future. For minor project updates, stakeholders thought digital engagement through social media and email
updates were most appropriate. Stakeholders were receptive to the idea of future briefings prior to outreach and project
milestones so they are kept in the loop. Several stakeholders also offered to share project updates through in-house
communication channels as well as post hard copies of project materials in their organizations' common spaces.
Stakeholders provided a list of languages to consider when translating materials for engagement activities and
communications. In alphabetic order, the languages identified include Amharic, Burmese, Dari, East African, Farsi, Indian
languages, Nepalese, Somali, Spanish, Tigrinya, Ukrainian, and Vietnamese.
Next Steps
The community engagement team will follow-up with previously identified stakeholders (Andrea Reay, Seattle Southside
Chamber of Commerce; Kris Kelly and Matthew Austin, Green River Trail) and offer another briefing opportunity. The
community engagement will also begin outreach to additional stakeholders to learn more about the Allentown
neighborhood and surrounding businesses. As interviews are conducted, this summary will be expanded to include their
feedback. The information gathered during the stakeholder interviews will inform planning and execution of future
community engagement efforts, including future online public meetings.
