Ferries - Mukilteo Multimodal Terminal Project

Project news

  • IMCO Construction mobilized at the site in early January to begin work on the terminal building, holding lanes, toll plaza, promenade, and landscaping elements.
  • 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.

Overview

The Mukilteo/Clinton ferry route is part of State Route 525, the major transportation corridor connecting Whidbey Island to the Seattle-Everett metropolitan area. It is one of the state's busiest routes, with more than 4 million total riders every year. By 2040, walk-on ridership during the peak afternoon commute is expected to increase 124 percent (2010-2040).

The Mukilteo ferry terminal is aging and hasn't seen significant improvements since the early 1980s. Components of the terminal do not meet seismic standards and its layout contributes to traffic congestion, safety concerns, and conflicts between walk-on and drive-on traffic. The new terminal, one-third of a mile east, will improve safety by meeting current seismic standards. It will also improve transit connections and passenger safety while streamlining passenger loading and opening the Mukilteo waterfront up to residents.

The site that used to house an abandoned U.S. Air Force fueling station will soon be home to a ferry building designed to be light on the earth and LEED Silver certified. Removing that old fueling pier also eliminated thousands of tons of toxic creosote-treated debris from Puget Sound. The existing ferry terminal remains open and the Mukilteo/Clinton ferry service unchanged during construction. 

The Mukilteo Multimodal Ferry Terminal project includes:

  • Passenger building and maintenance building
  • Passenger overhead loading
  • Toll plaza with four toll booths and seven vehicle holding lanes
  • In-water docking and loading structures
  • Transit center for connections to buses and trains
  • Signalized intersection and expanded vehicle holding area to reduce congestion on SR 525.
  • Waterfront promenade that will link up to a city park
  • Transit center located near the Sounder Commuter Rail Station

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
