Project Facts
- This project included construction of new channelization at the junction of Thacker Road and SR 26, near Othello.
- Besides the 148 miles of temporary pavement markings the project required, it installed 10,500 feet of new plastic center, crosswalk and stop-bar lines.
- The project also installed new plastic traffic arrows, railroad crossing symbols, bicycle lane symbols and surveillance markers.
This project was completed August 10th 2007.
This roadway preservation project chip sealed 141 miles on 11 state highways in Adams, Chelan, Douglas, Franklin and Okanogan counties. A project to build left turn lanes on SR 26 near Othello was incorporated into the seal project to save money and deliver the project sooner.
Why is WSDOT
Chip Seal these highways?
To preserve the roadways and improve the driving surface, a Bituminous Surface Treatment (BST), also known as a chip seal, was applied. It is a flexible, protective surface of asphalt emulsion and gravel that is applied to existing or repaired pavement. The following highways were resurfaced under this project:
- 21 miles of US 2 in Douglas County from Moses Coulee to the SR-17 Jct. near Coulee City.
- 9 miles of SR 17 in Franklin County from SR 260 Jct. vicinity to Adams County Line.
- 15 miles of SR 20 in Okanogan County from Winthrop to north of SR 153 Jct. near Twisp.
- 11 miles of SR 26 in Adams County from Grant County Line to SR 17 Jct. near Othello.
- 18 miles of US 97 in Chelan and Okanogan Counties from SR 150 Jct. near Chelan to Pateros.
- 22 miles of US 97 in Okanogan County from SR 17 Jct. near Brewster to Okanogan.
- 3 1/2 miles of US 97A in Chelan County from Chelan to US 97 Jct.
- 2 miles of SR 150 in Chelan County from Chelan to US 97 Jct.
- 8 miles of SR 153 in Okanogan County from Pateros to near Methow.
- 17 miles of SR 172 in Douglas County from west of Mansfield to SR 17 Jct.
- 0.3 miles of SR 213 in Okanogan County from US 97 Jct. to Malott.
- 15 miles of SR 971 in Chelan County from SR 97A Jct. north of Entiat to SR 97A Jct. near Chelan.
The End Result
This project extends pavement life and improves the ride quality and safety on 141 miles of state highway.
Project Benefits
Provides a waterproof layer protecting the underlying pavement.
Increased traction and skid resistance.
Fills cracks and raveled surfaces.
Provides an anti-glare surface when wet and increases reflectivity at night.

Increasing safety is one of our priorities
Besides the safety benefits of the project itself, safety for the public and the construction workers is paramount while the work is underway. During construction, a comprehensive traffic control plan and a work zone safety plan was in place to protect travelers and workers.
Will this project impact tribal resources?
After consultation with the Colville Tribes, no impacts were identified. At WSDOT, we seek to address the concerns of tribal nations using the process outlined in Section 106 of The National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOTCentennial Accord Plan. Part of this project was within the Colville Tribal Boundary. The Tribal Employment Rights Ordinances (TERO) was applied.
