SR 525 - Mukilteo Multimodal Terminal: What to expect during construction

November construction update

Night work to begin Dec. 9 and run through Jan. 25

In-water work began on the Mukilteo Multimodal Terminal Project in mid October. And now Manson Construction, our marine contractor, will begin work on 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 9:00 p.m. to 4:00 a.m. Consequently, crews must do this welding work for 16 nonconsecutive nights starting Dec. 9 and running through Jan. 25, 2020. 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 re-opening moves to December

Crews are currently working in all corners of the site right now -- building walls, sidewalks, First Street, installing utilities and drainage along with building the new passenger and maintenance buildings and toll plaza. Because of all this activity, it's not safe to re-open the pedestrian path until early December. We apologize for the delay. We were aiming to reopen the path in October, but crews encountered an extensive amount of buried debris (old wood pilings) when installing the water and storm pipes. This meant we had to make multiple changes to the area under the new holding lanes. Plus heavy rains in October caused their own delays. 

When it opens, the new path will be a paved sidewalk running along First Street, shown below. It will provide a safer way to access the waterfront and from which to watch the construction as it moves toward our goal of opening the new terminal in fall 2020.

The roof is up

Crews finished lowering 84 roof panels, measuring 10-feet by 20-feet each, onto the new Mukilteo ferry terminal building in early October. The panels are constructed of cross-laminated timbers, or CLT, which is wood stacked crosswise and bonded with structural adhesives. CLT panels provide the strength of traditional building materials but with a lower environmental impact, in keeping with our goal on this project to be “light on the earth” and LEED Silver-certified.

The Sounder roundabout
To build 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.

No in-water work happens 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 be LEED Silver-certified and 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.
