SR 525 - Mukilteo Multimodal Terminal

Mukilteo Ferry Terminal aerial photo

The existing Mukilteo terminal is aging and in need of major repairs. Visit our Flickr page to view more project photos.

The Mukilteo/Clinton ferry route is WSF's second busiest route for vehicle traffic; accommodating 4 million riders per year.

  • The first phase of construction, to remove the tank farm pier, began in late June. View the latest construction alert to learn more.
  • Pier demolition is expected to begin in August.
  • The work area around the tank farm pier will be closed to the public during construction. Recreational users, including divers, swimmers, and boaters are advised to use caution.
  • Please continue to check the project website or subscribe to our email listerv for updates as construction progresses.


In June 2013, Washington State Ferries (WSF) and the Federal Transit Administration (FTA) released the Final Environmental Impact Statement (EIS) for the Mukilteo Multimodal Project. The Selected Alternative (pdf 1.3 MB), known as a modified Elliot Point 2, relocates the ferry terminal one-third of a mile east of the existing terminal. View the latest project fact sheet (pdf 1.1 MB) to learn more.

Why is WSDOT considering improving or relocating the Mukilteo Terminal?
The Mukilteo/Clinton ferry route is part of State Route (SR) 525, the major transportation corridor connecting Whidbey Island to the Seattle-Everett metropolitan area. It is WSF’s busiest route for vehicle traffic and has the second highest annual ridership. During the afternoon peak commute period, walk on ridership is expected to increase 124 percent (2010-2040).

The Mukilteo terminal has not had significant improvements since the early 1980s and components of the facility are aging and do not meet current seismic standards. The current terminal layout makes it difficult for passengers to get in and out of the terminal and contributes to traffic congestion, safety concerns and conflicts between vehicle and pedestrian traffic. The new terminal will improve operations and multimodal connections and safety.

The End Result
The Selected Alternative, (pdf 1.3 MB), known as a modified Elliott Point 2, relocates the terminal to the western portion of the tank farm site. The project includes a new passenger and maintenance building, a supervisor’s building, four new toll booths and a new transit center. It is close to the commuter rail station. The existing tank farm pier will be removed, eliminating thousands of tons of toxic, creosote-treated debris from Puget Sound.

Project Benefits
The new terminal will:

  • Improve safety and accessibility for pedestrians, vehicles and bicycles
  • Improve the efficiency and reliability of ferry operations, including vehicle and passenger loading and unloading
  • Improve transit connections for riders who travel without a car and help ensure reliable multimodal connections 
  •  Reduce the ferry-related congestion along Mukilteo’s central waterfront
  • Provide public access to the Mukilteo waterfront

What is the project timeline?

  • 2010-2014 - Environmental process
  • 2014-2016 - Final design
  • Summer 2015 - Winter 2017 – Construction phase 1
  • 2017- 2019 - Construction phase 2 (depending on funding)

Financial Information

The project would cost approximately $129 million. The Legislature has identified funding for the project, which includes a mix of state funds and federal funds. WSF recently secured $16.8 million in federal grants and plans to begin first phase of construction in Spring 2015.
