In spring 2016, the city began working with affected neighborhoods in helping to identify traffic mitigation tools and locations to lessen traffic impacts due to East Link light rail construction. Specifically, East Link construction impacts Bellevue Way Southeast from near the current location of the South Bellevue Park and Ride along the roadway to the “Y” intersection (Bellevue Way and 112th Avenue Southeast) and extending onto 112th Avenue. The construction will involve building the guideway of the East Link light rail and South Bellevue station. Bellevue Way Southeast is a major arterial serving downtown Bellevue and the neighborhoods south of downtown. It is key connection for commuters entering and exiting Bellevue via I-90. When traffic becomes congested, typically southbound during the afternoon commute, some drivers bypass the congestion by using 108th Avenue Southeast and other neighborhood streets.
The Neighborhood Traffic Mitigation Committee (NTMC) includes a broad and geographically balanced representation from the neighborhoods of Bellecrest, Enatai and Surrey Downs and Beaux Arts Village. Membership includes one member of the Board of the above listed neighborhoods and 7 “community-at-large” members. The Committee is recommending mitigation with a "monitor and response" approach.
The NTMC has worked to recommend mitigation tools that best mitigate neighborhood traffic impacts resulting East Link construction which is now occurring on Bellevue Way (began in June 2017) and 112th Ave. SE (began July 2017).
Pilot project to discourage evening commuter traffic in neighborhoods proves effective
In response to concerns for increased traffic within neighborhoods during East Link light rail construction occurring on Bellevue Way SE and 112th Ave. SE, a pilot traffic mitigation program was implemented at 108th Ave SE at SE 16th St. and SE 16th St at Bellevue Way SE to discourage evening traffic in neighborhoods. The original pilot was launched in Sept. 2017 and modified in Jan. 2018.
Current features of the pilot program include:
- All motorists, transit and bicyclists must obey the all-way stop at the intersection of 108th Ave. SE at SE 16th St.
- No access to 108th Ave SE south of SE 16th St. is allowed Mon. through Fri., 4 to 7 p.m.
- No access to southbound Bellevue Way SE from westbound SE 16th St. is allowed Mon. through Fri., 4 to 7 p.m.
- Buses and bicyclists are exempted from the time-based turn restrictions.
The pilot was developed in collaboration between the Neighborhood Traffic Mitigation Committee and the Bellevue Transportation and Police Departments. The city has continually evaluated the pilot through traffic volume studies, operations, and community feedback. Data from an Oct. 2018 study shows continued decreases in traffic volumes from when the pilot turn restrictions were originally implemented.
The pilot has shown continued decreases in evening traffic on 108th Ave. SE and community feedback has been in support of the modifications. The city has determined to continue the pilot through the completion of major construction occurring on Bellevue Way SE and 112th Ave. SE which is expected in 2020 when these roadways will be restored.

Original Draft South Bellevue Traffic Mitigation Plan
In September 2016, residents of Bellecrest, Enatai, Surrey Downs and Beaux Arts Village received a mailer which seeks their feedback on a draft traffic mitigation plan to be implemented during East Link construction on Bellevue Way and 112th Avenue Southeast. The draft plan recommends strategic turn restrictions at key entrances in/out of these neighborhoods to deter commuter traffic from using neighborhood streets and is the recommendation of the Neighborhood Traffic Mitigation Committee (NTMC). Residents in the impacted neighborhoods were asked to complete an online survey by to share feedback that will be shared with the Neighborhood Traffic Mitigation Committee in late October. The online survey is closed.
The draft plan as proposed to residents is not being pursued.
South Bellevue East Link Construction Neighborhood Traffic Mitigation Kick-off Meeting
The city’s Transportation Department hosted an informational meeting on April 27, 2016 with the Bellecrest, Enatai and Surrey Downs neighborhoods and Beaux Arts Village to share background on known areas of traffic conditions and constraints, to receive additional feedback on other areas of concerns as they relate to East Link construction, and to address the next steps to form the South Bellevue East Link Construction NTMC. Below are the materials from the initial meeting:
- Presentation/Slideshow (PPT)
- Open House Display Boards
- Map of south Bellevue neighborhoods depicting existing traffic conditions and known traffic concerns
- Overall summary of the meeting
- Summary of comments (feedback cards)
- Summary of annotated maps at breakout tables (facilitated discussion)
- "Parking Lot" topics (identified at breakout tables; issues not directly related to South Bellevue East Link Construction)
