Ferries - Mukilteo Multimodal Terminal Project


What's happening now?

  • The first stage of construction, to build the new bridge seat and trestle, is underway. The contractor is currently installing in-water piles and preparing the upland area of the site for construction. The next phase of construction, to install deep stormwater utility lines, will begin in early 2018.
  • During construction, the waterfront path will remain open to pedestrians, but may be rerouted based on construction activities. Please obey all posted signs around the construction site.
  • 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 Project (pdf 3.31 mb) relocates the Mukilteo ferry terminal to the tank farm 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 is WSDOT 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 WSF’s busiest route for vehicle traffic and has the second highest annual ridership, with over 4 million total riders in 2015. 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.

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
