May/June construction update

Hammers began swinging again on May 4 after more than a month of work suspension to comply with Gov. Inslee's Stay Home, Stay Healthy order that took effect March 23. Business is not as usual. Only low-risk construction activities that workers can perform with six feet of distance between them are allowed. Safety measures are spelled out in a comprehensive COVID-19 plan that adheres to 30 safety protocols. A COVID-19 supervisor monitors workers to ensure all adhere to the plan, which requires health screenings at the start of each shift including temperature checks, maintaining six feet of distance at all times, wearing additional PPE onsite, and much more.

Work activities in June: 

Starting June 1 and running for two to three weeks, trucks will haul in materials to lay down the new holding lanes.

Trucks will use the special haul route that passes through the southern end of the old holding lanes and into the job site. Flaggers will coordinate the flow of trucks exiting the job site with the queuing ferry traffic. This work will take place from 7 a.m. to 2:45 p.m. Mondays through Thursdays and 7 a.m. to 1 p.m. on Fridays. 

These are not our usual holding lanes, either. They're a layer cake of materials designed to treat storm water before it leaves the site or enters Puget Sound. The holding lanes will be constructed of a special porous concrete called permeable concrete that allows rainwater to pass through and into a thick layer of sand that filters it. Then the water finds its way to an under drain system, the geo-membrane liner for which is shown in the photo above. This base layer collects and channels storm water into drain pipes so the filtered water can enter the Sound. 

Colorful elevator glass features tribal motifs

WSF is committed to honoring the history of the new Mukilteo terminal site as the home of the Coast Salish people and the spot where the tribes and U.S. Government signed the 1855 Point Elliott Treaty. During design consultation, the tribes asked us to be welcoming from land and water. These images on the elevator glass, designed by Tulalip Master Carver James Madison, will welcome all who come ashore. The east elevator is shown above; the west elevator features a similar design by Madison with a woman in the background. The special glass was installed over the past two weeks.

Seawall and promenade shaping up

Mukilteo seawall and promenade

The seawall, shown above, provides support for the waterfront promenade behind it. The promenade extends on the east and west ends of the passenger building. Wall outcroppings offer spots for pedestrians to linger, and benches -- of cedar and finished concrete -- provide places to sit and enjoy the view. Low-level lighted bollards and native vegetation will line the promenade. Interpretive signs, similar to those near the Mukilteo Lighthouse, honor the site's history.

The promenade path links the one at Lighthouse Park to the one at Edgewater Beach -- with a stop inside the new passenger building. (No ferry ticket needed to tour the building.) The pathway replaces the old asphalt one along the shoreline and it will be about 3 feet higher to account for sea level rise and because the site's previous refueling station had been constructed on a flood plain.

Wingwalls and piles

Ferry berthing structures

Marine crews took advantage of nightime low tides this past December, January, and half of February to weld areas of the wingwalls that are only accessible during very low tides. This shot above shows the ferry berthing structures in March when the marine contractor finished its work during the last fish migration window -- a time when crews can work below the water line. Marine crews drove all piles needed to support the overhead pedestrian walkway and the vehicle transfer span (below).​

The toll plaza will have four tollbooths; its roof is being installed now.

Marine crews constructed major portions of the new fishing pier that will open with the new ferry terminal in fall 2020. They will pick up where they left off in August when the next fish window opens and they can again work below the water line. The old Mukilteo fishing pier, owned by the Port of Everett, is attached to our old terminal and will come down with the demolition of that structure. The new pier will also be managed by the Port of Everett for the benefit of Mukilteo residents.

  • General work hours: Weekdays 7 a.m. to 6 p.m. and Saturdays 9 a.m. to 5 p.m. We don’t anticipate work on Sundays. Work is suspended now due to the coronavirus and the governor's Stay Home, Stay Healthy order. 
  • Fish migration window: There will be no in-water work mid February through July to protect migrating fish, in accordance with National Marine Fisheries Service, United States Fish and Wildlife, and Washington State Department of Fish and Wildlife requirements.
  • Construction lights will be directed away from our terminal neighbors.

Waterfront development: The project is one part of a larger redevelopment plan for Mukilteo's waterfront, which will include a replacement of the nearby NOAA research station, improved beach and trail access, the addition of mixed-use buildings, and more.
