2018 Open July 19, 2018. This intersection was originally accepted in 2012 as stop control (evolving to a signal with growth) for the first phase of a development. Because there was a long lapse prior to construction, it became subject to the WSDOT Intersection Control Evaluation process adopted July 2013. Subsequently, this is the first roundabout in WSDOT Eastern Region recommended by a consultant employing that process. ICD estimated from Google Maps linework.
