Gateway Completion Project

This project involves extending SR-509 to ease congestion on I-5, adding a southern access point to Sea-Tac International Airport and improve service between industrial districts by allowing general-purpose traffic and trucks to bypass I-5, SR 99 and local streets. When finished, SR 509 will become a key component of the Seattle and South King County transportation network. RES Group NW managed the overall relocation process while actively performing 120 relocations for non-residential and residential displacees. In addition, negotiated full and partial acquisitions. Property rights were acquired in accordance with the Federal Uniform Relocation Assistance and Real Property Acquisitions Policies Act (URA) and WSDOT Right of Way Manual.
