Every weekday approximately 26,000 vehicles pass through Island Crossing. The volume of traffic on SR-530 has increased so much that accessing onto SR-530 from uncontrolled intersections during morning and evening peak traffic is extremely dangerous. This is especially so at the Smokey Point Blvd. intersection where 4,500 vehicles a day access onto SR-530. Arlington worked with WSDOT to install a temporary traffic signal at the intersection of Smokey Point Boulevard and SR-530 while a permanent solution is implemented, the design and construction of a roundabout. The planned roundabout will increase safety, increase mobility and reduce backups. The temporary signal will remain as the City continues to work with WSDOT and stakeholders on the roundabout. The SR-530 Roundabout project will include a single lane roundabout (expandable to two-lane), crosswalks, center medians, sidewalks and street lighting.
This project is being completed as a partnership with the following team members:
