Northgate Pedestrian and Bicycle Bridge

Last Updated: February 21, 2017

Project Status Update

In mid-2016, we commissioned an independent cost validation of the initial 30% project design. From this, we determined that we cannot build the bridge as it was designed and stay within the available budget. A new design team has started revising the initial design to deliver a project that meets our design goals within our targeted budget.

We value the community input provided to date, and we’re continuing to incorporate community goals and priorities into the revised design where feasible. This includes lighting, crime prevention features, and connections to nearby walking and biking routes.

We expect to bring the revised 30% design to the community in the spring of 2017 and will share more information as it becomes available. Stay tuned!

Project Description

The Seattle Department of Transportation plans to build a new pedestrian and bicycle bridge over I-5 to improve connections within the Northgate community. This will include access to major regional transit facilities east of I-5: the King County Transit Center and the Sound Transit Light Rail station.

The project team has selected a tube/truss design with the main span crossing I-5 in the vicinity of 100th Street.

Additional pedestrian and bicycle improvements include:

  • A protected bike lane on the west side of 1st Avenue NE between NE 92nd Street and NE 103rd Street
  • A shared bicycle/pedestrian path on the east side of 1st Avenue NE between NE 103rd Street and NE Northgate Way

Project Benefits

The Northgate Pedestrian and Bicycle Bridge will benefit the area by providing:

  • A new connection between the east and west sides of I-5 in Northgate
  • A better connection for students and transit users to North Seattle College
  • Important access for bicyclists and pedestrians in the Northgate vicinity
  • Increased ridership at the King County Transit Center and future Light Rail Station

Project Funding

The project is currently estimated to cost between $26.3M and $32.8M. At this time, the project is funded by SDOT, Sound Transit, the 2015 Washington Transportation Package, and the 2015 Move Seattle Transportation Levy
This project was not selected for federal funding through the TIGER Grant program in 2014 and 2015.   
Due to the project’s placement in priority, funding from the Washington Transportation Package will be released in 2019. Construction is not expected to begin until all funding is readily available.
