🚧 ROAD WORK UPDATE – RAPID VALLEY CHIP SEAL PROJECT CONTINUES 🚧
As the chip seal project continues in the Rapid Valley area, some roads may appear to be finished. However, there is still one final step before the project is complete.
Beginning Wednesday, July 29, crews will begin applying the fog seal. This protective treatment is applied over the chip seal and gives the roadway its finished black appearance while helping extend the life of the road.
🚗 Please continue to keep all vehicles, trailers, campers, and other equipment off the roadway until all work has been completed. Vehicles left on the street may be towed at the owner's expense if necessary for crews to safely complete the project.
Thank you for your continued patience and cooperation as we complete these important road improvements.
