In consultation with neighbors, schools and stakeholders, the Neighborhood Transportation Safety Services group developed a traffic improvement strategy for the Northtowne area, along 100th Avenue Northeast, between Northeast 24th and Northeast 14th streets. The project also includes some side streets between 100th Avenue Northeast and 98th Avenue Northeast. The work focuses on addressing concerns about speeding and the need to improve safety for people who walk and bicycle in the neighborhood and around schools nearby. Phase 1 of the project, including the construction of a roundabout at 100th Avenue Northeast and Northeast 10th Street, was completed in spring 2021.
Phase 2 description
Construction of a second phase of improvements is scheduled to begin the first week of Jan. 2026 and will include:
- Sidewalk on the north side of NE 18th St (98th Ave NE to 100th Ave NE), east side of 98th Ave NE (NE 18th Street to NE 20th Street), north side of NE 21st St (98th Ave NE to 100th Ave NE),
- Shared use pathway on the east side of 100th Ave NE (NE 14th St to NE 24th St)
- Raised intersections with enhanced crosswalks on 100th Ave NE at NE 15th, 18th and 21st Sts.
- Raised crosswalks with Rectangular Rapid-Flashing Beacons (RRFBs) will be installed on 100th Ave NE at NE 14th St and NE 23rd St.
What to expect during construction
- Schedule: Construction is expected to Jan. 2026 and last through summer 2026. Please note that construction schedules are subject to change.
- Work hours: Work hours on 100th Avenue NE will be 7 a.m.-6 p.m. Work hours on NE 18th Street, NE 21st Street and 98th Avenue NE will be adjusted based on the bell schedules of the adjacent schools. All work is weather permitting.
- Impacts: Work on 100th Avenue NE will involve phased closures. Work will be phased in three segments on the north, central and south ends of the project. Each segment will include a closure of 100th Avenue NE to all non-local vehicle traffic, and flaggers will be enforcing this restriction during work hours. Vehicle access to side streets within the 100th Avenue NE closure area will only be maintained for streets that have no other vehicle access points. Access for people walking, rolling and biking will always be maintained.
The primary signed detour for each closure of 100th Avenue NE will use Bellevue Way NE to bypass the closure. Flaggers will alternate traffic to direct people driving, walking, rolling and biking around work zones on NE 18th Street, NE 21st Street, and 98th Avenue NE. Please follow flaggers’ instructions.
Funding
$1.3 million for Phase 1, funded by the Neighborhood Safety, Connectivity and Congestion Levy and other sources.
