The city of Maple Valley and Gary Merlino Construction Co. made improvements to the the SR 169/SR 516 intersection, also known as the "Four Corners" intersection. The city widened the roadway to add lanes and turn pockets, installed a new signal at SE 264th Street, and built new bike lanes, sidewalks, curbs and gutters.
The improvements will significantly reduce the number and severity of rear-end and sideswipe collisions. New sidewalks and bike lanes will also improve safety for pedestrians and bicyclists.
Over the next 10 years, it's estimated that the average travel time savings for drivers will be a total of 150,000 hours annually.
| Economic Incentive
Traffic will flow more efficiently through the intersection and drivers will have better access to businesses in the area.
