Ferries - Mukilteo Multimodal Terminal Project

Project news

  • The uplands contract to build the terminal building, holding lanes, toll plaza, promenade, and landscaping elements has been awarded to IMCO Construction. Work is scheduled to begin in early 2019. 
  • The contract for the remaining marine elements will be advertised to bidders in 2019. 
  • Preparation work to begin major construction of the new terminal was completed in fall 2018. This work included decontaminating the work site, building preliminary in-water structures, and laying the foundation of the new terminal building.

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 eliminated 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 more than 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. 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
