March construction update

The passenger building shell is closed in against the elements. Crews are now at work on the building's interior. This marks a significant milestone in WSF’s work to replace the 63-year-old, seismically deficient terminal on the Mukilteo waterfront with one that improves safety and efficiency for our passengers. What you see below is the north balcony -- the water-facing side -- where walk-on passengers and those in wheel chairs will use the overhead walkway to board the ferry.

Wingwalls and piles

Marine crews have driven all of the piles needed to support the overhead pedestrian walkway and the vehicle transfer span during this fish migration window, a time when crews can work below the water line. The fish window closed Feb. 15. Marine crews also 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.

Two of WSDOT's inspectors, Randy Hooper (left) and Ken Morley, often work in cold and wet conditions on the marine side of the new Mukilteo ferry terminal. Here they enjoy a March sun break. The duo inspects the drilled shafts for the vehicle transfer span (bridge connecting the ferry to land), supports for the overhead walkway, and the pile-driving for the wingwalls and dolphins. These structures keep the ferry in position while vehicles load and unload. Work on the in-water structures began in October 2019 and continues through March. It will resume in August when the fish window re-opens.

Fishing pier

Marine crews are also working on the new fishing pier that will open with the new ferry terminal in fall 2020. 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. Part of our agreement with the Port was to build a new fishing pier and, in our Memorandum of Agreements with the Tulalip, Suquamish, and Swinomish Tribes, we agreed to relocate it on the east side of our new terminal. That work is underway now.

Popular pedestrian path remains in its temporary configuration

The pedestrian path from the Sounder Train station east to the end of the work zone opened on Dec. 9. Crews have poured the sidewalks along the new First Street. Please use caution on the trail as the fence footings extend into the path. Some areas of the pathway may require pedestrians to step up or down a curb. Crews will continue making improvements to the pathway, pouring additional sidewalks and extending its length. When the project is complete, this sidewalk through what's now the work zone will be the permanent path and it will be ADA compliant. First Street, which will lead to the new holding lanes and transit center, is closed to vehicles until the new terminal opens next fall.

The Sounder roundabout
While building the new First Street, crews have reconfigured the roundabout in front of the Sounder commuter train station. There is still be space for vehicles to turn around there, but it's been changed to make way for construction. This new configuration will remain in effect until the new First Street opens next year.  

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.

There will be no in-water work during the fish migration window – 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.

Looking ahead to a terminal designed to LEED Silver standards and one that's light on the earth.

This site that formerly housed an abandoned U.S. Air Force fueling pier will soon be home to a building that’s light on the earth, integrating solar panels, natural ventilation, rain water harvesting, enhanced stormwater treatment, native plantings, and other green design elements into its design. This honors our commitments to tribal partners and the city of Mukilteo. Tribal cooperation was key to the project’s design. Terminal, toll booths, and other structures incorporate tribal cultural elements.

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.
