Sea-Tac Airport Opens New Northbound Airport Expressway and Return-to-Terminal Loop

The Port of Seattle opened Seattle-Tacoma International Airport's new Northbound Airport Expressway and Return-to-Terminal Loop roadway on March 27, 2008. The new loop ramp is intended to reduce traffic congestion on airport roads, particularly on the drop-off and pick-up curbs in front of the terminal. The new loop makes the return route simpler and faster, as traffic currently has been forced to exit off S. 170th St. to re-enter the expressway to the west. A new relocated exit for S. 170th St. moves to the east for easy access to International Boulevard.
