Road Alert: Starting 8/29 - W Snoqualmie Valley Rd NE between NE 80th St to NE Novelty Hill Rd

8/29 to 9/9: Chip Seal Pavement Preservation Work on West Snoqualmie Valley Road between NE 80th St to NE Novelty Hill Rd

Contractor crews working for King County Road Services will begin a multi-day process of applying Chip Seal to West Snoqualmie Valley Road between NE 80th St to NE Novelty Hill Rd. The crew is expected to work from 8 a.m. to 4 p.m. starting August 29 and could last up to September 9. Work on Saturday is likely. Crews may not be on site each day as the road needs to cure between steps. 

Crews will use a pilot car to guide traffic through the work zone. Please expect delays of up to 20 minutes and drive very slowly to keep the gravel on the ground. 

This work can be rescheduled due to weather, equipment, materials, or crew availability.

Chip Seal

• Asphalt mixed with water is sprayed on the road.
• A layer of small crushed gravel (chips) is spread and rolled in.
• The surface cures in 1–2 days, then loose gravel is swept away.
• Helps seal small cracks, improves traction, and extends road life.

Why chip seal here? With limited funding, chip seal lets us preserve more miles of roadway across unincorporated King County. While overlay is more durable, it’s also much more costly. Chip seal is a practical way to keep neighborhood roads safe and functional.

Addressing common concerns:

• Crews sweep up loose gravel after the curing process.
• We work to protect driveway connections and drainage.
• Feedback from residents helps us improve coordination with contractors on current and future projects.
• Please drive slowly in the work area do avoid kicking up loose gravel.

We know construction can be inconvenient, and we appreciate your patience as we work to keep our roads safe and maintained.
