SeaTac Sea-Tac International Airport Tukwila

Routes that could be affected: 128, 129 (new), 140, 156 (new), 170, and 180

Table of Contents

Why Metro is proposing this change:

  • 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 Tukwila Sounder (commuter rail) Station and Sea-Tac International Airport.
  • To minimize duplication of transit service to downtown Seattle.

Proposed changes

Route 128

  • Change routing to serve Tukwila International Boulevard Link Station.

Route 140

  • Change routing to serve Southcenter Boulevard, S 154th Street, the Tukwila International Boulevard Link Station, and SW 148th Street between Tukwila and Burien. Increase evening frequency of Route 140 to every 30 minutes. New Route 156 (see below) would provide replacement service to McMicken Heights, Sea-Tac International Airport, and the Tukwila Sounder Station.

Route 156 (new)

  • Create new route between International Boulevard, McMicken Heights, SeaTac, and Southcenter via the SeaTac/Airport Link Station at International Boulevard S / S 176th Street. Peak period trips would serve the Tukwila Sounder Station. New Route 156 would operate until approximately 9 p.m., every 30 minutes on weekdays and every 60 minutes on weekends.

Routes 170 and 129 (new)

  • Discontinue Route 170 and create new Route 129 to provide replacement peak-hour service on weekdays between Riverton Heights and the Tukwila International Boulevard Link Station, which would provide a connection to Link service to downtown Seattle. New Route 129 would operate five morning and five evening peak period trips on weekdays.

Route 180

  • Discontinue service to the Sea-Tac International Airport terminal, and provide service to Air Cargo Road. Route 180 would serve the SeaTac/Airport Link Station at International Boulevard S / S 176th Street.

Advantages

Route 128

  • The neighborhoods of Boulevard Park, Riverton Heights, and Tukwila would be connected to Tukwila International Boulevard Link Station.

Route 129 (new)

  • The Riverton Heights neighborhood of north SeaTac would be connected to Tukwila International Boulevard Link Station.

Routes 140 and 156 (new)

  • Route 140 would provide new service along S 154th Street and Southcenter Boulevard.
  • Route 140 would provide faster service between Renton, Southcenter, and Burien, which would benefit a majority of riders.
  • Route 156 would provide a new connection between International Boulevard, the SeaTac/Airport Link Station, McMicken Heights, and Southcenter.
  • Transit service would be more reliable because Route 140 would not be subject to delays and congestion on the Sea-Tac International Airport roadways.

Route 180

  • Route 180 would provide faster service between Burien, SeaTac, and Kent.
  • Transit service would be more reliable because Route 180 would not be subject to delays and congestion on the Sea-Tac International Airport roadways.

Disadvantages

Route 128

  • Travel times for some Route 128 riders between West Seattle or White Center and Southcenter would increase by five to eight minutes.

Routes 129 (new) and 170

  • Riders of current Route 170 between Riverton Heights and downtown Seattle would have to ride new Route 129 and transfer at the Tukwila International Boulevard Link Station to travel to downtown Seattle.
  • Riders of current Route 170 between McMicken Heights and downtown Seattle would have to walk to new Route 156 on S 176th Street and Military Road S, or to Route 180 on S 188th Street, and transfer to Link at the Sea-Tac/Airport Station to travel to downtown Seattle.

Routes 140, 156 (new) and 180

  • To get to or from Sea-Tac International Airport, riders of current Route 140 would have to transfer or take a different bus route.
  • Some riders who currently use Route 140 in McMicken Heights would have to walk farther to use new Route 156.
  • Riders on routes 156 and 180 would have to walk farther from the SeaTac/Airport Link Station to the airport terminal.
