Starting in late March, night owls and early birds in Seattle will get a new way to reach the airport. Transit agency Sound Transit is launching a trial overnight bus route that will run between Seattle-Tacoma International Airport and downtown during hours when light rail is not operating — from midnight to 4 a.m. Buses will depart every 30 minutes beginning March 28, providing around-the-clock public transit access to the air hub.
The route will run from the airport via the Tukwila International Boulevard light rail station to key downtown Seattle stops, including Sodo, Stadium, the International District/Chinatown and Westlake. It will bypass several stations south of the airport and north of downtown. As the head of Sound Transit noted, this pilot is especially important ahead of the FIFA World Cup that the city will host and will give greater flexibility to both passengers and airport employees.
Currently, getting to the airport by public transit in the dead of night or early morning is virtually impossible: light rail doesn't begin running until after 4 a.m., and the limited King County Metro night bus routes don't go far north of the airport and don't reach Seattle. The new service aims to address that gap.
