Point Defiance Bypass

The $181.2 million Point Defiance Bypass project will reroute Amtrak passenger trains to an inland rail line through DuPont, Lakewood, and Tacoma. It includes a new Amtrak station in Tacoma's Freighthouse Square. Sound Transit currently uses a portion of this route for Sounder commuter rail service between Tacoma and Lakewood.

This bypass project is part of a much larger 20-project construction program being delivered by WSDOT throughout western Washington to improve service for the entire intercity passenger rail corridor.

The Point Defiance Bypass project includes the new Amtrak passenger train station, 14.5 miles of new and upgraded track, and five reconstructed at-grade crossings - each with advanced warning and signal systems. When all work is complete in 2017 it will provide more frequent, reliable and faster Amtrak Cascades passenger rail service in Washington.


Why Reroute the Train?

It's hard to dispute the beauty of the scenic waterfront rout around Point Defiance. But that train route is congested with nearly 50 daily freight trains. As a result, passenger trains often are delayed as they maneuver around freight congestion, tight curves, single-track tunnels, drawbridge openings, and landslides.

For passengers, this means missed connections, delayed appointments, and lost time with family and friends. 

The new inland rail route will create room for Amtrak Cascades to add more daily trips between Seattle and Portland, shorten travel times, and reduce delays.

Track and Signal Work

The Point Defiance Bypass project is funded with federal American Recovery and Reinvestment Act (ARRA) High-Speed Intercity Passenger Raily dollars. It is managed and overseen by the Washington State Department of Transportation's Rail Division. 

WSDOT has contracted with Sound Transit to deliver the track and signal work, including: upgrading crossings, bridge rehabilitation and construction, and retaining wall construction. Sound Transit also will provide advanced notification of construction activities and respond to all construction-related inquiries. 

During the construction period, neighbors and motorists can expect to see work along the existing track route that includes: welding, grading, track installation, signal work, improvements of at-grade rail and roadway crossings, and testing of equipment and trains.

Traffic Signal Crossings

The project includes safety improvements at five traffic signals that have at-grade railroad crossings, including: 

  • Clover Creek Drive SW
  • North Thorne Lane SW
  • Berkeley Street SW (as part of the city of Lakewood Madigan Access project)
  • 41st Division Drive
  • Barksdale Avenue

Advanced notice will be given of any work affecting traffic and informational signs will be posted at the construction sites.

Notifications and Work Window

The Sound Transit project team's intent is to provide a two-week notice for construction activities. However, during construction some unanticipated and emergency work may be needed, which may result in shorter notification schedules. Sound Transit will actively work with residents, businesses, and jurisdictions to provide:

  • Advance notice of work that requires traffic control
  • Advance notice of nighttime work
  • Presentations to groups
  • Outreach through mailings and personal contacts
  • Updates on the project website
  • Regular email updates through the Sound Transit "Point Defiance Bypass Track Work" email subscription list. Email corrie.adams@soundtransit.org to subscribe.

Work Window

Work will occur primarily on weekends, beginning at midnight on Fridays and ending at 7 a.m. Mondays. However, some work will occur duing weekdays
