January construction update

Night work to run through Feb 15

In-water work began on the ferry berthing structures in mid October. And now Manson Construction, our marine contractor, is building the wingwalls. Crews need extremely low tides for extended periods of time so they can weld in locations that are normally below the water line. These extreme low tides occur between the hours of 6:00 p.m. to 4:00 a.m. The night work that began Dec. 9 will run through Jan. 25. Then, a second round of night work will start Jan. 27 and run to Feb. 15. The goal is to complete as much in-water work as possible within the fish window – a time when migrating salmon are less likely to be around. There will be no night work on Sundays or holidays. The City of Mukilteo has approved a noise variance for this work. 

What to expect during nighttime work:

  • Neighbors nearby may see and hear welding operations, hand tools, small power tools, and the engine of the derrick crane. Sound will dissipate as it moves away from the terminal. Also, the terminal sits between the working location and the homes that overlook the new terminal. 
  • Noise is 70-80 decibels at the source (equivalent to a passing car or bus) and will dissipate to 7-25 decibels (equivalent to rustling leaves) for neighbors 600 to 1500 feet away.
  • Crews will shut off equipment when not in use to minimize noise.
  • There will be no work on Sundays or holidays.

Pedestrian path reopened

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, also paved recently. For now, the pedestrian path is in a temporary configuration. 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.
