Project overview

The Northgate neighborhood is a major residential and employment hub. It’s 1 of 6
“urban centers” identified in Seattle’s Comprehensive Plan. An urban center is a relatively small area expected to accommodate high densities of development for housing and employment.

Northgate is also listed as a regional growth center in the Puget Sound Regional Council’s (PSRC) Vision 2040 regional growth management plan. With the completion of Sound Transit’s Link light rail station to the east of Interstate 5 (I-5) in 2021, the neighborhood is poised to become one of the region’s most active transit hubs.

Connecting communities on the east and west sides of I-5 in Northgate

We’re building a new pedestrian and bike bridge over I-5 in Northgate. The Northgate Ped and Bike Bridge will improve connections between the east and west sides of the Northgate community, helping knit together a neighborhood historically divided by a 10-lane interstate and maximizing the use of transit facilities. The King County Transit Center currently serves over 6,000 passengers a day, and the future light rail station is expected to serve over 15,000 passengers per day.

When complete, the bridge will help connect the neighborhood’s thriving job and retail centers with the rest of the city and region. The project will also connect to nearby walking and biking routes with a multi-use bike and ped path along 1st Ave NE between NE 92nd Street and NE Northgate Way.

The project consists of four main parts:

Related Projects:

Other projects we are coordinating with include:

  • Bridge spans over I-5

  • Western approach between North Seattle College and wetland area, connecting to College Way N and N 100th St

  • Eastern approach between I-5 and 1st Ave NE at NE 100th St, near the King County Transit Center

  • Multi-use path along 1st Ave NE

The project will benefit the area by providing:

  • A new connection over I-5, decreasing travel times for people walking and biking between the 2 sides of the highway

  • Safety improvements and access for people walking and biking throughout the Northgate area

  • Better access to regional transit at the King County Transit Center and future Link light rail station, resulting in increased use of transit facilities

  • Improved connections between the Northgate retail center for its employees and customers and for residents and visitors to other nearby amenities, such as parks and medical and social services

Recent cost-saving changes

The design team developed a bridge design that includes the following cost-saving changes and design improvements:

Original Design

Revised Design

20-foot wide walkway on bridge

16-foot wide walkway on bridge

2,100-foot long bridge length

Shortened bridge length to 1,900 feet

East approach conflicted with WSDOT Park-and-Ride at 1st Ave NE

East approach modified as it touches down near 1st Ave NE, simplifying the connection and preserving the WSDOT Park-and-Ride lot

West approach included stairs at the North Seattle College, with limited sight distance

West approach modified to improve sight distances and make a more direct connection

Complicated construction approach

Standard construction approach to reduce project duration

Tube/truss design (enclosed)

More open structure and more graceful bridge transition

Finally, an added benefit of the revised design is enhanced user experience with features such as a wetland wildlife overlook and a view of arriving light rail trains at NE 100th St.

What we’ve heard

Based on community input, we know there is interest in:

  • Minimizing environmental impacts of the bridge by making sure, for example, that the project doesn’t disturb wildlife during construction and ensuring the bridge’s drainage system (for stormwater) is designed to enhance wetlands on the west end

  • Ensuring safety of all bridge travelers

  • Understanding how the project is funded and the cost of the project

  • Connecting the bridge to other infrastructure, including neighborhood bike routes

  • Separating or managing modes of traffic on the bridge

We value the community input provided to date, and we’re continuing to incorporate community goals and priorities into the revised design where feasible.


Planning and design will continue through 2018. Environmental review is ongoing, with final permitting also complete in 2018. We expect construction to begin in 2019 and to be complete in 2020, prior to the opening of the Link light rail station in 2021.

We've secured funding from various sources in addition to the voter-approved Move Seattle levy. These include SDOT, Sound Transit, Washington State, and additional local funds.

Get involved

In the year ahead, as we finalize design of the bridge project, you'll have opportunities to learn more about it and provide feedback. Our team will be in the community making presentations, hosting public events, sending information to project neighbors, and hosting pop-up tables at busy public spaces. Email is the best way to stay up to date on the project and to get notifications about outreach events.
