Intersection Spotlight: Woodinville-Duvall Rd & W. Snoqualmie Rd

If you’ve ever driven this stretch, you know the challenge: backups, tricky turns, and safety concerns. While this intersection isn’t within Duvall’s city limits, it absolutely affects our daily lives — and neighbors have asked me about solutions, including whether a roundabout might work here.

The good news: This intersection is already flagged in King County and regional transportation plans for improvements.

Options under study include:

• A roundabout (improved safety and flow, but requires more land)

• Turn lanes and channelization (focused fixes, less disruptive, but not a full solution)

• Signal upgrades (modern signals that adapt to traffic, though still stop-and-go)

Each approach has trade-offs. The final choice will depend on traffic studies, crash history, safety, and community input. Also, in the PSRC Regional Transportation Plan (2022-2050) appendix, Woodinville-Duvall Road is identified as a corridor needing operational and safety enhancements; intersection improvements are among the strategies listed.

What matters most is that we keep this project moving forward. With improvements already happening nearby on Woodinville-Duvall Rd — like bridge upgrades and corridor planning — fixing this intersection is the next big step toward safer, smoother travel for everyone.

I’ll keep sharing updates as the County moves into the study and outreach phase. Together, we can push for an improvement that makes sense for Duvall and the Valley.
