Highways and interchanges are the backbone of our transportation network, handling everything from local commutes to regional and interstate travel and critical freight movement. However, as growth continues, many high-volume facilities operate at or beyond capacity. At SCJ Alliance, we’ve led numerous Interchange Justification Reports (IJR) to develop targeted improvement strategies that enhance capacity and efficiency.

Our team has the expertise and finesse to bring together a wide range of stakeholders—including local agencies, WSDOT, and private development interests—building consensus to implement solutions that meet current demands and future growth.
