North Seattle Neighborhood Greenway

Updated: December 31, 2018

What’s happening now?

Under construction

Construction for the North Seattle Neighborhood Greenway started this summer 2018 and is scheduled to be substantially complete spring 2019. Work will continue through the holiday season; crews will not work on January 1. 

We continue to work throughout the corridor to upgrade crossings for people walking and biking, and along the new neighborhood greenway route installing traffic calming speed humps, and new signs and pavement markings.

Please be aware and follow the traffic changes at N 100th St and College Way N, and see the "Intersection Improvements" section for more details about these changes. Please also follow the posted signs and detours near 3rd Ave NW and NW 92nd St, and N 100th St and Aurora Ave N, when traveling through these areas.

Other major work zones include 3rd Ave NW and NW 92nd St, N 100th St and Greenwood Ave N, and Holman Rd NW and 13th Ave NW New Signal.

Seattle Squeeze:

It's time to get ready - Starting January 11, 2019, the Puget Sound region will experience the longest closure of a major highway when Washington Department of Transportation (WSDOT) closes the Alaskan Way Viaduct to complete the work needed to open SR 99 tunnel 3 weeks later. Everyone traveling in the region will be impacted.

About neighborhood greenways

Neighborhood greenways are safer, calmer residential streets for you, your family, and neighbors. We make people walking and biking the priority. The North Seattle Neighborhood Greenway includes:

  • 20 mph speed limit signs
  • speed humps to calm traffic
  • stop signs for side streets crossing the neighborhood greenway
  • signs and pavement markings to help people find their way
  • easier crossings of busy streets with crosswalks, flashing beacons, a roadway island, or traffic signals

We considered the following factors to select the greenway design and route:

  • The Bicycle Master Plan (BMP) recommended a neighborhood greenway on NW/N 90th St and N 100th St to connect to the planned Northgate Pedestrian & Bike Bridge across I-5. Protected bike lanes on N 92nd St were also proposed in the BMP and then prioritized in our recent implementation plan.
  • Community input and feedback from hundreds of people through public meetings, site visits with community members, an online survey, and direct communications. We heard a lot of requests for a neighborhood greenway with slower speeds on residential streets, safer crossings at busy intersections, flatter routes with less cut-through traffic, and improved connections to nearby schools, parks, transit, popular business districts, and Seattle’s growing bikeway network.
  • Data on traffic speed and volume, roadway operations, and street use.

The selected route along N 100th St/NW 92nd St avoids the steepest hills and prioritizes streets with lower vehicle speeds and volumes. It also connects people to the destinations we heard were most important:

  • Parks: Soundview Playfield, Crown Hill Park, Sandel Park, and Licton Springs Park
  • Schools: Whitman Middle School, Eagle Staff Middle School, Cascadia Elementary School, Licton Springs K-8 School, Greenwood Elementary School, St. John Catholic School, and North Seattle College
  • Neighborhoods, business districts: Crown Hill, Greenwood, Licton Springs, and Northgate
  • Citywide bike network: 17th Ave NW Neighborhood Greenway, Greenwood Ave NW bike lanes, Fremont Ave NW Neighborhood Greenway, College Way N bike lanes, and N 92nd St bike lanes
  • Transit: RapidRide lines on Holman Rd NW and Aurora Ave N, bus routes on Greenwood Ave N and College Way N, and future Northgate Pedestrian & Bike Bridge to light rail

Like all our neighborhood greenway streets, the North Seattle Neighborhood Greenway will include speed humps, prioritize people walking and biking, and improve crossings of busy streets.

About the school safety project

Our Safe Routes to School program funded crossing improvements at 15th Ave NW and NW 92nd St at Whitman Middle School, NW 80th St and 1st Ave NW at Greenwood Elementary School, and the Safe Routes to School Connections providing neighborhood greenway routes to the school on 1st Ave NW and the new schools at the Wilson-Pacific site: Eagle Staff Middle School, Cascadia Elementary School, and Licton Springs K-8 School.

About the Neighborhood Street Fund projects

Our neighborhood greenway work has been closely coordinated with the Neighborhood Street Fund's 2018 projects in the area: Holman Rd NW and 13th Ave NW Signal and Aurora Ave N Corridor Improvements.


The North Seattle Neighborhood Greenway & School Safety Project and associated Neighborhood Street Fund projects began construction in 2017. We expect to finish building these improvements in early 2019.

2017 (completed)

  • N 92nd St Protected Bike Lanes (initially marked in October 2016, weather delayed until early 2017)
  • 1st Ave NW Neighborhood Greenway Connection (N 92nd St to N 73rd St)

2017-2018 (completed)

  • Safe Routes to School Education and Enforcement Campaign

2018 (under construction)


This project is funded by the 9-year Levy to Move Seattle, approved by voters in 2015.

The Neighborhood Street Fund program pays for transportation projects identified and prioritized by the community. Projects range from crossing improvements to creating unique public spaces. They're typically between $100,000 and $1 million. The 2019 application for NSF projects is open now – apply by November 19!

The Safe Routes to School connections were paid for by a Washington State Department of Transportation Safe Routes to School grant.

Seattle Squeeze

Seattle is entering a new era of tough traffic when WSDOT permanently closes the Alaskan Way Viaduct on January 11, 2019, and the new SR 99 tunnel opens three weeks later in early February. This closure is the longest highway closure in the history of the Puget Sound Region, and just the beginning as private and public construction projects will continue to change how we move and deliver goods over the next five years. SDOT and its partner agencies are working together to manage congestion during this challenging period, limit the impact on commuters and businesses, and keep downtown open for business. 

However, traffic disruption during this period is unavoidable, and commutes are going to get longer. Everyone traveling to and in Seattle needs to have a plan. To minimize those disruptions and ensure that first responders and emergency vehicles can still move quickly through Seattle, everyone traveling to and in Seattle needs to have a plan for commuting to work or school, appointments, and/or running simple errands. 

Check out the Seattle Squeeze website and factsheet for more information.
