WSDOT lowers speed limits on six-mile stretch of SR 20 in Oak Harbor

Drivers on State Route 20 in Oak Harbor were facing a permanent slowdown across the six-mile corridor from Penn Cove to Southwest Barlow Street, with new posted limits of 45 mph between mileposts 24.95 and 30.26, 35 mph from 30.26 to 30.77, and 30 mph from 30.77 to 31.29. A full run through that stretch works out to about 9 minutes at the new limits, roughly 1.5 minutes longer than holding 50 mph over the same distance. New signs were scheduled for the week of Monday, May 11, and the lower limits became enforceable as soon as they were installed.

The Washington State Department of Transportation said the reductions were meant to better match current driving speeds, traffic volumes, the road’s design, and the surrounding land use. Within Oak Harbor city limits, WSDOT worked closely with the city on the changes; south of the city limits, the agency said the lower speeds were prompted by questions from community members and a review of traffic patterns. The new limits mirror the practical reality of the corridor, where traffic shifts from the Penn Cove side into town and past Southwest Eagle Vista Avenue, Southwest Swantown Avenue, and Southwest Barlow Street.

Oak Harbor’s City Council had already moved to align local code with WSDOT’s recommendations earlier in 2026. The ordinance lowered the speed entering the city near Southwest Eagle Vista Avenue from 50 mph to 35 mph, kept the transition from the former 40 mph zone near Southwest Eagle Vista Avenue to near Southwest Swantown Avenue at 35 mph, and dropped the stretch near Southwest Barlow Street to 30 mph. City staff said the changes fit Oak Harbor’s Active Transportation Plan adopted in 2024 and its Comprehensive Safety Action Plan adopted in 2025.

The council approved the local changes unanimously, but the discussion was not without resistance. Island County resident Tabitha Bailar objected during public comment, saying the road segment is not a school zone or a heavily trafficked pedestrian area. Councilmember Christopher Wiegenstein defended the reductions as necessary even if they made some drivers uncomfortable, and Councilmember James Marrow said he had been told by a traffic law enforcement chief that the loudest complainers are often the fastest drivers.

The May change also fits a broader reset on Highway 20 speeds in Oak Harbor. In September 2025, WSDOT and the city were already weighing a reduction near West Fakkema Road tied to a new compact roundabout north of town, a debate that showed how closely the agency and city were revisiting speeds as development, traffic and safety concerns changed along the corridor.
