• The final piece of the region chip seal project was finished the week of September 11 when crews applied the permanent plastic pavement markings.

This P-1 Roadway Preservation project rehabilitated or chip sealed 210 miles of highway on eight highways in Chelan, Douglas, Grant, and Okanogan Counties.

Why did WSDOT repair and resurface these highways?

This project included crack sealing only for:

• I-90 MP 148.44 to MP 175.60 - George to Moses Lake and MP 181.77 to MP 191.89 - SR 17 to Warden
• SR 17 MP 67.75 to MP 96.55- Ephrata to Coulee City and MP 98.30 to MP 119.67 - Coulee City to Bridgeport
• SR 153 MP 8.00 to MP 30.74 - Methow to SR 20

and...pavement repair, crack sealing, and chip sealing for:

• US 2 MP 90.72 to MP 99.04 - Tumwater Canyon
• SR 28 MP 10.17 to MP 19.12 - Rock Island to Crescent Bar
• SR 173 MP 0.00 to MP 11.99 - Bridgeport to Brewster 
• SR 281 MP 0.00 to MP 10.54 - George to Quincy 
• SR 283 MP 0.05 to MP 14.74 - George to SR 28

This project also included building a two mile long passing lane on SR 28 at Spanish Orchards and a "cushion course" rehabilitation of SR 283 which added six inches of new road bed under the new surface.
