International Way Grade Separation Project

Project Information

International Way provides access to the Port's administrative office, Port tenants' facilities and neighboring industries. Site access currently requires passing through one of three at-grade rail crossings. The primary entry is International Way. At this intersection, rail traffic occasionally disrupts vehicle traffic entering or exiting Port property.

The Port completed a transportation analysis to better inform infrastructure investments and prepare for anticipated growth. The study identified the need for an overpass as the Port at International Way to eliminate rail/vehicle conflicts. The project, identified as the International Way Grade Separation Project, is in the initial planning and engineering stages. Building an overpass will improve traffic flows that benefit freight mobility, ensure access for emergency services and provide a safe route for vehicular traffic.

Proposed Alternative

The overpass will be located roughly along the existing alignment of International Way. At the initial planning and engineering stages of the project, the Port had previously developed and shared three alternatives, all of which required Columbia Boulevard to be closed on either side of International way. After hearing input from the local community, stakeholders and local impacted neighbors, the Port has proposed a new alternative which allows Columbia Boulevard to remain open to through traffic, as shown below:

The project is anticipated to go to construction in 2030 – 2032.
