Following completion of the 133rd Avenue NE extension to Woodinville-Snohomish Road, construction of a new roundabout at the intersection of Woodinville-Snohomish Road and Little Bear Creek Parkway (NE 177th Place) began in summer 2025. The project is designed to improve traffic flow, enhance safety, and strengthen connections for people traveling by vehicle, bicycle, and foot.

A key feature of the project is a dedicated pedestrian and bicycle tunnel beneath the roundabout. The tunnel provides uninterrupted access for Eastrail users while reducing conflicts with vehicle traffic at the intersection.



Traffic Notice

Construction crews have shifted work on the 133rd Ave NE roundabout project to the west side of the site, resulting in a temporary traffic change. On June 11, 2026, a portion of Little Bear Creek Pkwy (177th Place) was closed to through traffic between a point east of Homeward Pet and 134th Ave NE. Access reopened on Woodinville-Snohomish Road. The closure will remain through summer 2026, with the roadway reopening when roundabout is completed.


Traffic Impacts

  • Local access to businesses will remain open
  • Traffic flaggers on-site to manage business access and traffic flow.
  • Brief delays are expected as construction vehicles enter and exit the work zone




Roundabout Project Benefits

  • Improved Traffic Flow: Roundabouts keep vehicles moving more efficiently than traditional signalized intersections, helping reduce delays and improve travel times.
  • Reduced Congestion: The project provides an alternative route through downtown, helping relieve traffic on the heavily traveled NE 175th Street corridor.
  • Safter Trail Crossings: A dedicated Eastrail tunnel beneath the roundabout allows pedestrians and cyclists to cross safely, separated from vehicle traffic.
  • Better Downtown Connections: The roundabout improves access to and from downtown for drivers, cyclists, and pedestrians.
  • Enhanced Public Spaces: The project creates opportunities for landscaping, pollinator-friendly plantings, public art, and future trail corridor improvements
  • Roundabout Public Art: The center of the roundabout will feature River, a sculpture created by Wildheart Designs. The artwork will serve as a visual landmark and contribute to the character and identity of the corridor.
