Argo Yard Truck Roadway

(East Marginal Way Phase II)

The Port of Seattle is the lead agency in a coalition including the Freight Mobility Strategic Investment Board (FMSIB), the Union Pacific Railroad, AMB Properties and the City of Seattle, which will build a dedicated one-way truck roadway providing a safer and faster truck freight route from the port marine terminals to the Union Pacific Argo Yard rail gate.
 
The truck roadway would be constructed from the east side of the SR 99/East Marginal Way trestle underpass to the existing Colorado Street cul-de-sac. The Project also will include the improvement of Colorado Street and Diagonal Avenue from the southern end of the new truck roadway to SR 99/East Marginal Way.

Project Elements

The roadway project is envisioned in three elements:
  • Element I: The Port will construct and maintain a 1500’ long, 16’ wide south-bound dedicated truck-only roadway between the SR 99/East Marginal Way trestle underpass and the existing Colorado Street cul-de-sac.
  • Element II: Improve the public roadway system of Colorado Street and Diagonal Avenue from the southern end of the truck roadway to SR 99/East Marginal Way at Diagonal Street, and construct the undercrossing of the SR-99 trestle south of Duwamish Avenue at the project’s north end.
  • Element III: Union Pacific will construct a new automated gate system to improve efficiency when entering the Argo Yard.

Project Status

A Memorandum of Understanding defining partners’ roles and responsibilities was completed in January 2012. Design and Right of Way will be completed in late-2012. Construction will begin in early 2013 and be completed in 2014.
