Project Overview

As Seattle grows, improvements to freight mobility are essential to promote regional and international economic competitiveness. 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). It is also a designated Heavy Haul Route, critical last-mile connector and vital route for over-sized trucks or those carrying flammable cargo.  In addition, the corridor provides a major connection for people who bike between the West Seattle Bridge Trail, downtown, and the SODO neighborhood.

This project will:

  • Improve safety and reliability in the movement of people and goods
  • Support freight loads by rebuilding the roadway
  • Promote efficiency through signal modifications and intelligent transportation systems (ITS)
  • Improve safety by better separating non-motorized modes from freight traffic


Project Benefits

  • Improved freight mobility –Support the economic vitality of our region including the Port of Seattle and local industrial businesses.
  • Safety - Better access and connections in combination with separating non-motorized modes to reduce potential conflicts.
  • Better pedestrian and bike connections – New and upgraded facilities for people walking and biking also improves access for employees using transit or non-motorized modes to get to work in the area.

Project Funding

Funding to evaluate alternatives and complete early design is provided by the 9-year Levy to Move Seattle, approved by voters in 2015. Learn more about the levy at

Full funding is dependent on contributions from other public partners such as the Port of Seattle and the State, as well as competitive Federal grant programs such as FASTLANE. Learn more about FASTLANE grants at:

Public Outreach

This project began in 2015 with the examination of existing conditions and community input. A variety of methods engaged stakeholders, such as briefings, a public workshop, and an online survey.

In 2017, we are using public input, data collection, and technical analysis to evaluate different options for the future of the corridor.
