Almost 7 million pounds of concrete — roughly the equivalent of seven Boeing 747s loaded for takeoff – went into the foundation of the future passenger building of the Mukilteo Multimodal Terminal Project. Crews wrapped up the foundation’s construction in September, one year after it began. The foundation will support the building, trestle, and support system that holds the moveable bridge connecting the ferry to land.

On the heels of this, crews finished boring the final 487-foot-long underground tunnel that holds the stormwater utility pipes. This bore was the riskiest and longest of the project, 75 percent of the total 650 feet of pipe. We used an underground boring method rather than digging an open trench to uphold our commitments to local tribes and to minimize ground disturbance, lowering the risk of soil settlement for nearby Sound Transit and BNSF structures. Next, crews installed manhole access to the stormwater system in October, completing this phase of the project.
The utility work and the building foundation set the stage for the second phase of construction – the terminal building, vehicle holding lanes, toll booths, and other components – expected to begin in early 2019.

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 busiest routes in the state, with more than 4 million total riders every year. The terminal has not had significant improvements since the 1980s and components of it do not meet current seismic standards. The new Mukilteo ferry terminal, one-third of a mile east of the current one, will provide passengers with improved transit connections, safer and more efficient loading facilities, and improve access to the Mukilteo waterfront.
This project has come a long way from the first public scoping meeting in October 2011. Feedback gathered at 11 public meetings and 24 briefings with local elected officials, businesses, and community groups helped shape the design of the new Mukilteo ferry terminal to make it a unique part of our ferry system and a centerpiece of the Mukilteo waterfront.
