Downtown Demonstration Bikeway

The Transportation Department celebrated the opening of the Demonstration Bikeway on July 31, 2018 (video). It provides a safer and more comfortable route for people to bike north-south in Bellevue's busiest neighborhood. The bikeway is on 108th Avenue Northeast, from Main Street to Northeast 12th Street.


The project is funded by the Neighborhood Safety, Connectivity and Congestion Levy, which was approved by voters in 2016. The project installed:

  • Separated bike lanes on both sides along most of the street. Lane dividers include painted buffer areas, temporary curbs and posts, and planter boxes.
  • Striped bike lanes in narrow road segments, such as intersection approaches at NE 4th, 6th, and 10th Street, and shared lane markings at two existing median islands where the road is too narrow for bike lanes.
  • Additional bike safety improvements including green pavement markings highlighting mixing areas between bikes and cars, such as turn lanes and high-traffic driveways.


A before-and-after study was conducted to assess the outcomes of this project for all street users, including people bicycling, walking, driving, using transit, and transporting goods, based on data and community engagement. The following reports provide insights into community outcomes related to the topics of safety, efficiency, and livability.
