Officials Reassess Highway 20 Speed Limits Around Oak Harbor
City and state transportation officials reviewed proposed speed limit changes along Highway 20 at a November 28 meeting, taking into account citizen concerns and recent collisions. The adjustments, if approved, would lower speeds through key segments and near a new roundabout, affecting drivers, enforcement and traffic flow for Island County residents.

City Engineer Alex Warner briefed the Oak Harbor City Council on November 28 about a series of traffic studies and proposed speed limit adjustments being conducted by the Washington State Department of Transportation. WSDOT recommended reducing the speed limit from 40 miles per hour to 30 miles per hour between Barlow Street and Swantown Avenue. South of Swantown Avenue the state proposed a 35 mile per hour limit that would continue further south to create a smoother transition into denser urban sections.
The city also pressed for a lower posted speed approaching the new roundabout at West Fakkema Road. State engineers had earlier floated a 45 mile per hour approach, while some council members argued a 40 mile per hour posting would be safer because drivers are braking suddenly at the roundabout. WSDOT traffic engineer Joshua Shippy said the state would rely on its updated traffic study and noted that the state secretary of transportation has final authority over speed limit changes on state highways, including within Oak Harbor city limits.

Outside city limits WSDOT is considering reducing a 50 mile per hour zone south of Libbey Road to 45 miles per hour after recent crashes and several fatalities prompted a fresh safety analysis. Those potential changes are part of a broader reassessment of traffic patterns on both the north and south ends of Oak Harbor as development and travel behavior shift.
Once WSDOT completes its analyses the city plans to consolidate recommended adjustments into an ordinance and is likely to return the issue to council in early 2026. Implementation typically includes a grace period before strict enforcement. Police Chief Tony Slowik said the department will use radar trailers with messaging to help drivers adjust to new posted speeds and to encourage compliance before issuing citations.
For local residents the outcomes will affect commute times, pedestrian and cyclist safety, and how law enforcement manages enforcement. The process underscores the interplay between state jurisdiction over highway speeds and city priorities for traffic safety and livability.
