Once open, the walking and biking trail will run parallel to Woodinville-Snohomish Road and connect up to Northeast Mill Place.
The city also plans to start construction on another project to extend this trail even further in January 2027. Eventually, the trail is expected to stretch across downtown Woodinville and join with the Eastrail, a planned 42-mile regional trail connecting Snohomish to Renton.
“I think this is a starting point, a trigger for engaging this whole [Eastrail] corridor,” said Asha D’Souza, director of Woodinville’s Public Works Department. D’Souza added that the roundabout is part of a series of projects, including replacing the trestle over State Route 202, that the city has planned around the trail.
Woodinville officials expect both the roundabout and the trestle project to increase Woodinville’s capacity for growth and improve traffic in the downtown area.
In October 2023, the Woodinville City Council considered design proposals to connect Woodinville-Snohomish Road and Little Bear Creek Parkway, looking at both a roundabout and a signal. Based on an analysis by construction consulting firm Parametrix, the cost to build the roundabout was estimated at $2.7 million to $3.2 million, with an added cost of up to $5.5 million for the trail tunnel below. The estimated cost to build a signal instead was $3.65 million.
After moving forward with the roundabout design, the City Council approved an $11.9 million construction contract for the project in June 2025.
Construction on the roundabout started in July 2025 and was completed this October. In the center of the roundabout, the City of Woodinville installed a blue abstract sculpture mimicking a river, a design the City Council selected in August 2025.
Although the project is complete, Woodinville-Snohomish Road and Little Bear Creek Parkway have not been fully reopened. Cars can travel east on Little Bear Parkway towards 134th Avenue and west on Woodinville-Snohomish Road onto 133rd Avenue. The roundabout and trail are expected to open by Nov. 4, 2026.
