South approach to Sea-Tac Airport closing at night

Construction of an expansion of Sound Transit’s Link light rail line is altering the way South Sound residents reach Sea-Tac Airport late at night and early in the morning through Dec. 18.

Crews are blocking off the South 182nd Street entrance to the airport from International Boulevard from 11:30 p.m. to 5:30 a.m. through that date to allow the lifting of concrete sections into place for the new elevated light rail route.

Sound Transit and the airport recommend that airport users approaching from the South on International Boulevard follow detour signs northward to South 170th Street and from there to the terminal. Traffic on the arrival drive is also being affected by the construction.

Traffic on that drive is being rerouted onto the northbound Airport Expressway. Traffic can exit the expressway at South 170th Street and then to southbound International Boulevard or follow the expressway to I-5 southbound near Southcenter.

The light rail system, which now connects the airport with downtown Seattle, is being extended southward to a new station at Angle Lake at South 200th Street.
