Road Construction
The news you need to navigate during road construction projects to improve traffic flow in and out of Sea-Tac Airport.
160th Street to Hwy 518 Eastbound now open
Looking to head east on Highway 518 from the 160th Street? A new eastbound on-ramp is now open on the Airport Expressway at 160th Street.
Rerouted Exit from the Airport Garage
All traffic leaving the airport's parking garage now exits slightly left over a new roadway that goes under the Link Light Rail Station and out to the North Airport Expressway. This route provides easy freeway access for both north and southbound drivers.
Exiting customers who wish to head south on International Boulevard (SR-99), are no longer able to use the first exit to South 170th St. Instead, drivers are directed to go around via the freeway system, or use the Return to Terminal loop ramp and exit at South 170th St. Whichever direction you’re going, please avoid returning through the airport drives.
Please use extra caution and watch carefully for other vehicles.
