Des Moines — SeaTac — Sea-Tac International Airport — Tukwila
Routes that could be affected: 128, 140, 170, and 180; potential new routes: 127 and 156

Why Metro is suggesting changes

  • To provide service connections between local communities and the Tukwila International Boulevard and SeaTac /Airport Link stations.
  • To provide more direct service between Burien, Southcenter, and Renton.
  • To maintain a connection between the Sounder (commuter rail) Tukwila Station and Sea-Tac International Airport.
  • To minimize duplication of transit service to downtown Seattle.

Suggested changes

  • Change Route 128 to serve Tukwila International Boulevard Link Station.
  • Change Route 140 to serve Southcenter Boulevard, S 154th Street, the Tukwila International Boulevard Link Station, and SW 148th Street between Tukwila and Burien. Route 140 would no longer serve Sea-Tac Airport and McMicken Heights.
  • Create new Route 156 between Des Moines, McMicken Heights, SeaTac, and Southcenter via the SeaTac /Airport Link Station at International Boulevard S/S 176th Street.
  • Discontinue Route 170 and create new Route 127 to provide peak service between south SeaTac, McMicken Heights, and the Tukwila International Boulevard Link Station, providing a connection to Link service to downtown Seattle.
  • Change Route 180 to discontinue service to the SeaTac /Airport Link terminal, and provide service to Air Cargo Road. Route 180 would serve the SeaTac /Airport Link Station at International Boulevard S/S 176th Street.

SeaTac/Airport Link light rail station

The SeaTac/Airport Station will be located near the northeast corner of the main airport parking garage, just west of the intersection of S 176th Street and International Boulevard (State Route 99). There will be a direct pedestrian connection from the station to the airport ticket counters and SeaTac’s City Center. The walk from the station to the airport terminal building is about 1,000 feet.

Advantages

  • Boulevard Park, Burien, Des Moines, McMicken Heights, Riverton Heights, SeaTac and Tukwila neighborhoods would be connected to Link light rail stations.
  • New all-day service would be provided along S 154th Street by Route 140.
  • Route 140 would provide faster service between Renton, Southcenter, and Burien.
  • Route 156 would provide a new connection between Des Moines, S 200th Street, the SeaTac /Airport Link Station, McMicken Heights, and Southcenter.
  • Route 180 would provide faster service between Burien, Kent, and Auburn.
  • Transit service would be more reliable since bus routes would not be subject to delays and congestion on the Sea-Tac International Airport roadways.

Disadvantages

  • Travel times for some Route 128 riders between West Seattle or White Center and Southcenter would increase by about five minutes.
  • Riders of the current Route 140 who are travelling to or from Sea-Tac International Airport would have to transfer or take a different bus route.
  • Current Route 170 riders between McMicken Heights and downtown Seattle would have to transfer at the Tukwila International Boulevard Link Station.
  • Current Route 170 riders would no longer have service to 24th Avenue S and Airport Way S.
  • Route 180 riders would have to walk farther from the SeaTac /Airport Link to the airport terminal.
