Allentown Truck Reroute Project

Project Status Update

For the City to determine a preferred alternative to reroute the existing truck traffic, an Environmental Impact Statement (EIS) must be conducted. The EIS will include robust community outreach and opportunities to engage for all interested parties on potential alternatives for freight traffic. Council approved moving forward with the EIS at the June 14, 2021, Committee of the Whole Meeting.

As of July 2021, the City is looking to hire a project manager to oversee the EIS to determine an alternative access route for existing truck traffic. The City will also hold monthly meetings with the Allentown community to provide updates on the EIS and hear firsthand about questions and concerns.



3rd and 4th Quarter of 2021 Hire Term-Limited Project Manager
4th Quarter of 2021 Begin monthly progress meetings with the Allentown Community on November 23, 2021
1st Quarter of 2022 Start Request for Qualifications process for EIS consultant, select consultant, and bring contract to Council for approval
2nd Quarter of 2022 Start the EIS
4th Quarter 2023 Complete the EIS and report to Council and the Allentown Community


Allentown Community Meetings

Meetings will be held on the 4th Tuesday of every month from 5:30-6:30pm at the Tukwila Community Center. The first meeting will be held on November 23, 2021.

Project Overview

In 2015, the City of Tukwila and BNSF jointly funded an access study to determine a potential new alternative route for truck traffic into the intermodal yard.

  • Trucks currently access their destinations via 42nd Avenue S and S 124th Street through the Allentown neighborhood.
  • The City is examining the feasibility of the previously-identified existing route options identified in the 2016 BNSF Alternative Access Study, evaluating them given current conditions and broad screening criteria.
  • As part of the study, open houses were held and community input was collected.
  • The exploration of these alternatives is still in the early stages. The City will ensure its findings and any actions are communicated clearly to the community.


The following four alternatives are being considered along with the status quo (42nd Ave. S. bridge/S 124th St.):

42nd Ave S Bridge/S. 124th St. (Status Quo)
This is the current route most trucks and vehicles use to access the facility. This will be considered the no-build or baseline alternative.

Gateway Drive – North Leg
This proposal would connect with the existing gate through the north leg of Gateway Drive, a new roadway between the Boeing Employee Credit Union and ITT Technical Institute building, and a new bridge over the Duwamish River.

48th Avenue S
This alternative accesses the facility at the south end via the existing 48th Avenue S roadway and a new bridge over the Green River Trail and Duwamish River.

S 112th Street
This alternative accesses the facility at the northern half via a new roadway along the existing Seattle Public Utility and Seattle City Lights utilities corridor.

Airport Way S
This alternative accesses the facility at the north end via an existing railroad access road that goes under Boeing Access Road and Sound Transit Link Light rail line.

Frequently Asked Questions

Does the City of Tukwila have a preferred alternative access option to reroute freight traffic?
The City has no preferred option for alternative access to BNSF’s facility. An EIS must be conducted for the City to determine a preferred alternative to reroute the existing truck traffic. The EIS will include robust community outreach and opportunities to engage for all interested parties on potential alternatives for freight traffic.

Does replacing the 42nd Ave S Bridge impact community efforts to reroute freight traffic from S 124th St?
No. The work to replace the 42nd Ave S Bridge is a public safety project and has zero effect on the larger community effort to reroute freight traffic off of S 124th St. The City of Tukwila is committed to collaborating with the Allentown community regarding freight traffic through the neighborhood and that collaboration is an entirely separate effort from the 42nd Ave S Bridge replacement. Further, the City Council has directed staff to engage in an Environmental Impact Statement (EIS) process – a necessary step to determine a preferred alternative– to further evaluate alternatives for freight traffic on this route. The EIS process will have significant opportunities for community input.

How is the Environmental Impact Statement (EIS) being funded?
City funds will cover the cost of the EIS.

The US Congress is considering spending trillions of dollars on infrastructure – has the City of Tukwila applied for those funds to reroute freight traffic?
The City has not applied for infrastructure funding to reroute traffic. The City must complete the EIS process in order to determine a preferred alternative and then begin design work before any such project would be a candidate for funding.

What is the role of BNSF in this process?
We anticipate that BNSF will be an engaged stakeholder in this process, and we are including them when we share information, where appropriate, including invitations to public meetings. As with the larger Allentown community, BNSF is an important stakeholder going forward regarding any conversations about rerouting freight traffic.

How can residents be involved in this process?
The City will begin regular, monthly meetings with the Allentown community in the fourth quarter of 2021. Residents are encouraged to attend these meetings for updates. In addition, the City website will be updated as the different projects progress. Finally, the EIS for the truck reroute effort is a comprehensive analysis that includes several opportunities for public comment and the community is encouraged to provide comments.

Have you thought about developing a citizen task force about this issue?
The City has been working with the Allentown Advocates and will continue to work with them throughout the duration of these projects.
