The project was advertised for private contractor construction bids on Mar. 25, 2013. Bids were opened Apr. 18. On Apr. 20, contract #8458 was awarded to Granite Construction Co. for $889,550.32 with construction starting this summer and expected to be complete in the fall.
A well attended open house was held in Okanogan on Sept. 19, 2012. Input received generated a revised intersection improvement design alternative. (Read the news release)

In this (I-2) Highway Capital Safety Improvement - Collision Prevention Project, WSDOT is addressing two intersections on US 97 in Okanogan. One is the Cameron Lake/Armory Junction Roads intersection and the other is the Oak Street/Airport Road intersection.
Why is WSDOT
planning to improve these intersections?
US 97-Cameron Lake/Armory Jct. Roads Intersection
There have been 11 collisions at the US 97 and Cameron Lake /Armory Junction Roads intersection from 2006 to 2011. A number of them were "T-bone" collisions which produce a higher percentage of severe injuries and fatalities. A 2012 review of traffic moving through the intersection showed that 30 to 35% of all the vehicles turned into or out of Armory Junction Road. The volume combined with the collision history demonstrated that something needs to be done at this location. A number of different solutions were considered for this intersection from signs to signals to turn lanes to roundabouts.
US 97-Oak Street/Airport Road Intersection
At this intersection WSDOT is trying to reduce potential collisions by addressing conflict points for traffic turning off US 97. The preferred alternative plan adds left turn lanes on US 97 for both northbound and southbound traffic. These new lanes will provide a refuge for vehicles stopped on the highway waiting to make a left turn, allowing through traffic to continue without having to stop as motorists do now.
On average, the Cameron Lk. Rd. intersection handles 6,200 vehicles per day; Oak St., 4,100. (WSDOT 2011 Annual Traffic Report)
The End Result
The projects are designed to reduce the number and severity of collisions at these intersections while efficiently moving traffic.
- Provide advance notice to highway drivers that vehicles are entering from the side roads.
- Reduce the number of conflict points between through and turning traffic.
- Provide a dedicated lane refuge for drivers turning from US 97.
- Reduce delays and increase mobility for drivers on US 97 because they don't have to stop and wait for traffic making left turns from US 97.
What is the project timeline?
Construction starts this summer and is expected to be complete in 35 working days, by this fall.
