Redwood Highway chip seal begins June 17 between O’Brien and California border

June 10, 2024

O’BRIEN – Drivers should expect congestion and delays along Redwood Highway (U.S. 199) between O’Brien and the California border next week due to a chip seal project.

Construction will require lane closures from milepost 36 to milepost 41, Monday through Friday, June 17-21. Most work will take place during daylight hours. Traffic control will be provided by flaggers and pilot cars. Most delays will be less than 20 minutes.

Due to loose rock on the roadway, drivers are advised to slow down and allow additional space between vehicles.

This is the final segment of work for a project that began last summer and paved the highway from Cave Junction to O’Brien. Work was suspended in September due to hazardous conditions related to nearby wildfires.

Prime contractor Knife River Materials will return in late June or early July to apply permanent striping to this area. This work may also require intermittent lane closures.

This $8.5 million project also added several safety features along Redwood Highway and applied a chip seal to an 8-mile section of Oregon 42 (Coos Bay-Roseburg Highway) near Winston.

Local driveways: In areas where the highway is limited to a single lane for construction, local residents are asked to wait at the end of their driveways for a pilot car before turning onto the highway. ODOT will post signs at each driveway, and flaggers will provide traffic control at local intersections.
