Yamhill County advances road repairs, safety signs and bike planning after public‑works update
Loading...
Summary
County Public Works outlined summer construction and safety upgrades — including a July full‑depth North Valley repair with a possible 14‑day closure, new solar speed signs, and reuse of asphalt grindings — while the RIAC highlighted crash mapping and a newly posted 50 mph limit on North Valley Road.
The Yamhill County Board of Commissioners heard a detailed Public Works briefing on April 2 about several major road and safety projects the county plans for 2026, and a companion presentation from the Rose Improvement Advisory Committee (RIAC) on crash mapping and speed‑limit recommendations.
Public Works Director Mark Lago said crews and contractors will prep the county's chip‑seal and overlay projects this spring and begin a large North Valley Improvements job in July that includes four long full‑depth repair sections. "To accomplish this work, we will need to close the road for up to 14 days," Lago said, and the county will place reader boards and post notices two weeks beforehand. The project will replace buried sections up to 3 feet deep, install geofabric layers, and replace several large pipes.
Lago also detailed materials and maintenance steps planned for the summer, including a 2026 chip‑seal contract with Sierra Santa Fe and annual bridge inspections for National Bridge Inventory (NBI) and non‑NBI bridges. He reported the county received a 2,300‑ton pile of asphalt grindings, screened it down to about 2,000 tons of usable material and estimated it "saved the county between $25,000 and $50,000" when reused for widening shoulder sections on McDougal.
RIAC Chair Ryan Webb described the committee's role advising Public Works on master plans, crash pattern analysis and safety measures. Webb said RIAC recommended a revised posted speed on North Valley Road following an ODOT study; "now it's posted speed limit is 50," he said, and he expressed hope the combination of engineering work and posting will improve safety.
Webb reminded the public of continued collaboration with George Fox University students on capstone projects and invited residents to a bike‑focused presentation April 9 (6–8 p.m.) at the Yamhill County Public Works Building. He also summarized RIAC recommendations to tighten right‑of‑way permit requirements — including requiring traffic‑control plans for closures and vegetation restoration inspections.
What happens next: Public Works said it will publish closure notices, place reader boards two weeks before the North Valley closure and post project updates on the county website and social media. The George Fox capstone presentation is open to the public on April 9 at the Public Works building.
