Seylor Valley Road, Confederated Tribes of the Colville Reservation

Nespelem, Washington

Akana provided professional engineering services for the design of approximately 4.42 miles of improvements to Seylor Valley Road between Bridge Creek Road and Lynx Creek Road on the Colville Reservation. Under the project, the existing gravel roadway, which is crossed by three cattle guards, nine culverts, and one pipe arch stream crossing, as well as 27 driveway or dirt road approaches onto the road, will be widened and paved, and culverts crossing the road will be improved or replaced. Guardrail also will be added to the stream crossing at the Hall Creek pipe arch.
