WSDOT will "chip-seal" the following highway sections:
- SR 20/Ferry County Line to Republic
- SR 21/US 395 to I-90
- SR 21/Wilbur to Keller Ferry
- SR 21/Republic to Canada
- SR 26/Washtucna to LaCrosse
- SR 174/Vicinity of Electric City to Wilbur
- SR 260/Kahlotus to Washtucna
- SR 263/Snake River to Kahlotus
- US 395/Boyds to Canada
In addition, several streets within the towns of Kahlotus, Washtucna, and Wilbus will be chip-sealed.
Why is WSDOT
chip-sealing these highways?
To preserve the roadways and to improve the driving surface, a Bituminous Surface Treatment (BST), also known as a chip seal, will be applied. It is a flexible, protective surface of asphalt emulsion and gravel that is applied to existing or repaired pavement.
The End Result
This project extends pavement life, and improves the ride quality and safety on 158 miles of state highway.
Project Benefits
- Provides a waterproof layer protecting the undrlying pavement.
- Increases traction and skid resistance.
- Fills cracks and raveled surfaces.
- Provides an anti-glare surface when wet and increases reflectivity at night.
What is the project timeline?
The project will be advetised for bids shortly. Work will be underway this summer.
Financial Information
- Pre-Existing Gas Tax - $7-9 million
- Total Funding from all sources - $7-9 million
