Overview
This preservation project paved 128 miles of 7 state highways in Adams, Chelan, Douglas, Grant and Okanogan Counties to preserve the roadways and to improve the driving surface.  A Bituminous Surface Treatment (BST), also known as a chip seal, is a flexible, water resistant, protective surface of asphalt emulsion and gravel that is applied over existing pavement.

The following highways were resurfaced:
1. 22 miles of SR-17 in Adams and Grant Counties from Othello to Moses Lake. (Includes building a left turn lane at Baseline Rd., just below I-90 and intersection safety improvements at Cunningham Road, Lee Road, Road 2 SE and M SE.)
2. 21 miles of SR-17 in Grant County from US-2 near Coulee City to SR-174.
3. 16 miles of SR-17 in Douglas & Okanogan Counties from Bridgeport to US-97.
4. 14 miles of SR-20 in Okanogan County from Aeneas Valley Road to Wauconda Summit.
5. 16 miles of SR-24 in Adams County south of Othello.
6. 18 miles of SR-26 in Adams County from Othello to the SR-395. (Includes intersection improvements at "B" SE.)
7. 12 miles of SR-173 in Douglas County from Bridgeport to Brewster. (To save money for the City of Bridgeport, chip sealing of Columbia, Fairview and 10th Street was incorporated into this contract.)
8. 5 miles of SR-207 in Chelan County from Coles Corner to Lake Wenatchee.
9. 4 miles of SR-282 in Grant County from Ephrata to SR-17.
Construction began April 14th and was complete on September 12th, 2008.
