Highway & Interchange Studies

Our highest volume transportation facilities are highways and interchanges. The amount and variety of use—local commute trips, regional and interstate travel, freight movement—strain many of these facilities. And growth in many areas has maxed out their capacity. We’ve led a number of Interchange Justification Report (IJR) efforts to identify improvement strategies for area interchanges. Our staff has the finesse to build consensus between varied stakeholders from local agencies to WSDOT to development interests.
