The project to improve traffic flow and relieve congestion along Argonne Road between Knox and Trent in Spokane Valley began Monday.
While most of the work will be conducted during nighttime hours, traffic restrictions will remain in place through the daytime. Access to businesses will be available throughout the project.
The project starts with reconstruction of the intersection at Argonne and Knox to widen the radius of the corners to facilitate smoother turns. While that work is under way from May 11 through mid-June, traffic on Argonne will be reduced to two lanes in each direction. Only right turns will be allowed on Argonne and Knox; there will be no left turns from any direction of the intersection while that work is under way until about mid-June.
The work will then move to the Argonne/Montgomery intersection where a new northbound right turn lane will be added. Changes to crosswalks will consolidate all east-west pedestrian traffic on Montgomery at Argonne to the crosswalk north of the intersection, and the lightly-used crosswalk south of the intersection will be eliminated. A new traffic camera to help respond to changing traffic needs will also be installed.
In late July, work is expected to move to the Argonne/Trent intersection where another traffic camera will be installed. The project also includes signal/pole relocations or replacements at the Montgomery and Knox intersections.
Ramps complying with the Americans with Disabilities Act will also be constructed at the Knox intersection.
Funding for the $1.7 million project comes from the Federal Highway Administration ($1,106,000) and the city of Spokane Valley ($606,000).
