2 Million Dollar Chip-Seal Project Begins on US 101 in Grays Harbor County

Chip-sealing repairs pavement damage and extends the life of the roadway. The treatment also improves safety for motorists by providing a smoother, skid-resistant driving surface. Centerline rumble strips are grooves or rows of raised pavement markers placed perpendicular to the direction of travel. As a vehicle passes over the rumble strips, noise and vibration are produced alerting inattentive drivers when they are crossing over into on-coming traffic. For more information on the chip-seal process, visit You can also visit to learn about rumble strips.
