Sound Transit is replacing platform edge tiles at SeaTac Airport Station from July 15 to Sept 6. The maintenance work will occur from 10 p.m. to 6 a.m. each day.

During this time, trains will share one track, requiring passengers to board all trains on the platform to Northgate. Passengers should pay attention to platform closure signs, the train’s head sign, and listen for announcements before boarding.

Additional travel time may be experienced during this project. Check the ST Trip planner for transit updates.
