Ferries - Mukilteo Multimodal Terminal Project

Project news

  • Contractor bids for the construction of terminal buildings and other major components of the project have been rejected because they exceeded funds available for the project. Plans are in place to revise the contract and solicit new bids this fall.
  • Work to remove the old fuel pier (also known as the 'tank farm') has already been completed, and work continues to prepare the site for the remainder of construction.
  • The waterfront path remains open to pedestrians, but may be rerouted or temporarily closed based on construction activities. Any closures will be signed in advance. Please obey all posted signs around the construction site.
  • Construction work hours are 7 a.m. to 6 p.m. on weekdays and 9 a.m. to 5 p.m. on Saturdays. No work will occur on Sundays or holidays except by City of Mukilteo exemption.

The Mukilteo Multimodal Terminal Project relocates the Mukilteo ferry terminal to the abandoned fueling facility site, one-third of a mile east of the existing terminal. The project includes a new passenger and maintenance building, a supervisor’s building, transit center and four new toll booths. Its location near the Sounder commuter rail station improves transit connections. Removal of the tank farm pier eliminates thousands of tons of toxic creosote-treated debris from Puget Sound.

Why are we replacing 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 one of the busiest routes in the state, with over 4 million total riders every year. 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 new Mukilteo ferry terminal will provide passengers with improved transit connections, safer and more efficient loading facilities, and improve access to the Mukilteo waterfront.

Needs & 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
