Design Status

The project team has completed 60% design. In this phase of design, there is a defined project footprint and a strong sense of what the project will look like. The project team has also identified where there may be impacts in the project area and the extent of those impacts. Further detail will be added in subsequent design phases. Once design is finished, the project team will create construction documents and a contractor will use those documents to build the project.

The project team is refining design for all three project sections and continues to meet with adjacent property owners, Sound Transit, WSDOT, and neighborhood associations for input on the project footprint and anticipated impacts.

Check out the updated renderings and graphics below and share your thoughts on each section of the project.

Community Input to Date

The project team sought public input during the early design and planning phases through community briefings, an online presentation, and a virtual open house. Community input contributed to decisions about what type of bridge will be built and how the bridge will connect to both the new station on the east side of I‑5 and 1st Avenue NE on the west side of I‑5.
Learn more about what we heard from the community during the first virtual open house in spring 2020 (PDF).

East Bridge Landing

The East Bridge Landing—on the east side of I‑5—will take pedestrians and bicyclists to the future Shoreline South/​148th Station where they can hop on Sound Transit light rail or buses and connect with the Trail Along the Rail (most sections of this trail to be completed in later years). The Sound Transit light rail station will include bicycle parking. The direct ramp design will eliminate the need for stairs to reach the platform, providing easy access for travelers on foot, on bicycle, or using assisted modes of travel such as wheelchairs.

Bridge Span over I‑5

The bridge will carry pedestrians and bicyclists over I‑5 between the Parkwood neighborhood on the west side and the new Shoreline South/​148th Station on the east side. The side-by-side arches and supporting cables of the bridge will create space and light for people using the bridge and those traveling nearby. The bridge will be wide enough to accommodate pedestrians and bicyclists traveling in both directions and will comply with the American with Disabilities Act (ADA) standards.

All elements will have lighting and safety features, including screening (throw barrier) to protect drivers on the interstate below from falling objects. The bridge will be built largely off-site, minimizing construction impacts over I‑5.

West Trail Connection

This ramp and approach to the bridge will be on the west side of I‑5 in the Parkwood neighborhood. The project team is working with immediate neighborhoods, including three places of worship, to ensure that the design and construction of the bridge will limit any disruptions. This portion will connect the bridge to 1st Avenue NE via a 16-foot shared path and planted buffer.
