S Lander St Bridge Project

Improving safety and relieving congestion in Seattle's SODO neighborhood

What’s happening now?

Design on the S Lander Street Bridge Project has progressed since our last open house in September 2016. We held our third open house on March 30, 2017, where visitors had the chance to view the latest design renderings and learn more about the project. We also shared an early preview of construction, which is anticipated to begin in early 2018.

Click to view map South Lander St is an essential east-west connection in Seattle’s SODO neighborhood. Every day, the street serves over 13,000 vehicles, 1,400 pedestrians, 100 bicyclists, and needs to be closed over 100 times per day for train crossings. This active train crossing causes frequent traffic delays and poses a potential safety risk, especially for people walking and biking. As the region continues its rapid growth and rail operations in the area expand in the coming years, the S Lander St "bottleneck" could put the Pacific Northwest's economic vitality at risk.

Watch this time-lapse video of the S Lander St crossing to see typical weekday traffic volumes and interactions between the corridor's many users.

To improve local traffic circulation, rail operations, and safety, SDOT will build 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.

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 announced this project was 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. For more information on the FASTLANE Grant Program, click here.


We're committed to keeping you informed and working with neighbors to limit construction impacts to the extent feasible. Here are some ways to get more information about the project:

Why is this project important?
The S Lander St Bridge will enhance mobility in this critical freight corridor and improve safety for people walking, biking, and driving.

How will the project create more reliable freight movement? The bridge will create reliable access adjacent to one of the largest port operations in the United States. It will improve safety for the more than 3,000 freight rail cars per day on the tracks, and reduce truck delays, congestion and emissions for more than 13,000 vehicles each day including 1,400 surface freight trucks per day. This project will improve the reliability of the last-mile connections between the Interstates and the Port of Seattle and area manufacturing in the Duwamish Manufacturing Industrial Council (MIC), the largest MIC in the state.

How will the bridge benefit people walking and biking?
The new bridge will feature a 14-foot walking/biking path on the north side of the bridge that is physically separated from the road. The bridge approaches will also include new curb ramps that meet current standards for accessibility.

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


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

East Marginal Way Corridor Improvement Project - East Marginal Way is a major freight corridor that provides access to the Port of Seattle terminals, rail yards, industrial businesses, and the regional highway system, and between local Manufacturing and Industrial Councils (MIC's). In addition, the corridor provides a major connection for people who bike between the West Seattle Bridge Trail, downtown, and the SODO neighborhood.

The project will improve safety, efficiency, and reliability in the movement of people and goods. We will rebuild the street to support freight loads, promote efficiency in reduction of bottlenecks through signal modifications and intelligent transportation systems (ITS), and improve safety for all modes by better separating non-motorized modes from freight traffic.

You are also invited to participate in the project's open house, April 12-26,
