Beginning January 8, 2025, through 2026, construction will take place at SeaTac Airport Station to add a new elevator to the pedestrian bridge. The new elevator will provide an additional option for passengers to travel from the pedestrian bridge to the pickup/drop off parking lot adjacent to the station. During construction, passengers can expect pedestrian walkways to occasionally be blocked or narrowed, and access to the current elevator periodically interrupted.

During times where pedestrian walkways are blocked and elevator access is unavailable, passengers may catch the Rapid Ride A Line bus from SeaTac Airport Station to Tukwila International Boulevard Station in order to use the 1 Line.

The pedestrian bridge from the station to the airport will be unaffected and available throughout the duration of this project.

Beginning February 10, 2025 half of the passenger pick up/drop off area will be closed, as will some parts of the plaza near the stairs and existing elevator as equipment begins to come in for construction of the new elevator.

Additional information about changes in elevator accessibility will be provided as it comes available.

The ONLY vehicles allowed access during the construction will be those using the ADA parking spaces and paratransit bus service. We apologize for any inconvenience this may cause.
