SR 530 - 59th & 211th Roundabouts

Project Description 

The City of Arlington is working with the Washington State Department of Transportation (WSDOT) on two very important transportation safety improvements on SR 530; the installation of roundabouts at 59th Ave and at 211th Place.  WSDOT has recently programmed and funded the design and construction of these two single lane roundabouts to increase safety and mobility on SR-530. These two intersections are currently non-controlled and have been the site of many accidents and traffic delays; the roundabouts will provide a safe travel route for all vehicles that use this roadway.
