S Lander St Bridge Project


At our open house, you can view the latest design renderings, and learn more about the project. We'll also share an early preview of construction, which is anticipated to begin in early 2018.

  • When: Thursday, March 30, 4 – 6:30 PM
  • Where: Metropolist, 2931 1st Ave S, Seattle, WA 98134 

Last updated 3/14/17

Design on the S Lander Street Bridge Project has progressed since our last open house in September 2016. As you may know, S Lander St is an essential east-west corridor in Seattle's SODO neighborhood and provides connectivity between nearby neighborhoods. Every day, the street serves freight, commuters, pedestrians, and bicyclists, as well as King County Metro buses and the Port of Seattle. The corridor also includes a crossing of four railroad tracks, causing frequent traffic delays and posing a potential safety risk.

To improve traffic, rail operations and safety, SDOT will build a bridge on S Lander St between 1st Ave S and 4th Ave S. SDOT is currently advancing the project design thanks to the voter approved Levy to Move Seattle and funding from the State legislature.

Every day, roughly 100 train crossings occur on S Lander St and surrounding streets. As a result, the street is closed for nearly 5 hours per day, impacting the mobility of tens of thousands of people and affecting freight access to port and manufacturing facilities critical to the local and national economy. As the region continues its rapid growth and rail operations in the area expand in the coming years, the S Lander St "bottleneck" will further put at risk the Pacific Northwest's economic vitality.

How Lander Will Be Fixed
The S Lander St Bridge project will construct a bridge over the railroad tracks on S Lander St between 1st Ave S and 4th Ave S. This crossing will provide a roadway unimpeded by rail operations, improve safety, and relieve congestion in Seattle's SODO neighborhood.

Why is this project important?
The S Lander St Bridge Project will help relieve traffic congestion and improve safety for cars, pedestrians and bicycles in a key freight corridor.

How will the project create more reliable freight movement?
The grade separation will create dependable access to one of the largest port operations in the United States. It will improve freight train movements for more than 3,000 rail cars and reduce truck delays, congestion, and emissions for more than 13,000 vehicles each day. This key connection will also improve reliability of travel to Interstates 5 and 90 and other key national freight corridors.

Will this project address safety and access in the SODO neighborhood?
The project will increase safety by separating trains from people driving, walking, and riding bikes and create an unimpeded access point for emergency responders. The bridge also provides access between regional transit hubs and employment centers.

Why is SDOT updating the design?
Seattle's transportation system has gone through many changes since the project's previous design process in 2007. New bridges and ramps have been completed at SR 519 and S Spokane St, and the Alaskan Way Viaduct replacement tunnel and roadway alignments are now known, all changing the way the area is used in meaningful ways. SDOT is reevaluating the design to ensure the most effective solution and the most efficient use of public funding.

How will construction impact businesses and commuter traffic in the area?
This project is still in the design phase, so no immediate impacts are anticipated. Construction is expected to begin in early 2018, and SDOT will work to ensure that all users of S Lander St and the adjacent area are informed about impacts during construction. In the long term, this project will greatly improve mobility and safety for users of the S Lander St corridor.



From 2003-2007, SDOT began the early stages of design and the process of meeting with property owners immediately adjacent to the project. This work was conducted until the project was placed on hold in March 2008 due to funding limitations. Click here see planning documents from that effort.


While on hold for several years due to funding limitations, the S Lander St Bridge Project has been reactivated thanks to the voter-approved Levy to Move Seattle and appropriations from the Washington State legislature.

On July 6, 2016, the US Department of Transportation (USDOT) announced that this project has been selected to receive a $45 million award under the Federal FASTLANE Grant Program, the largest grant award for Washington State. This is a new grant program created under the Fixing America's Surface Transportation (FAST) Act and passed by Congress in late 2015 to fund critical freight and highway projects across the country.

SDOT plans to complete the project design and start bidding for the design-bid-build S Lander St Bridge Project in summer 2017.


SDOT is committed to engaging adjacent businesses, area stakeholders, and the broader community in these early project design conversations. You can get involved by emailing or calling 206-684-5321.

In addition to soliciting input, SDOT is committed to keeping the community informed through updates at key project milestones.
