WSDOT plans to construct an additional one mile of general-purpose capacity by adding an auxiliary lane on southbound SR 167 between SR 516 and South 277th Street in Kent. The project aims to address operational challenges and will be constructed using existing shoulder pavement.
What to expect
The project will address operational challenges on SR 167 by creating one mile of new general-purpose capacity for SR 167. Currently, heavy on-ramp and off-ramp volumes at these interchanges create a bottleneck on SR 167. The auxiliary lane will help smooth out heavy merging and diverging vehicles between these interchanges. There will be minimal construction impacts to the traveling public as this project utilizes shoulder pavement within existing right of way.
