Seattle Multimodal Terminal at Colman Dock Project - What to expect during construction

During construction, Colman Dock will remain open and operational with the same number of Bainbridge Island and Bremerton sailings each day. While the contractor will complete most of the work from barges on the water, space on the dock will be limited because of construction work zones.

Learn how pile driving is done, view our blog post: Piling on the piles at our flagship ferry terminal 

  • Pile-driving occurs Monday through Saturday, during daylight hours, August through mid-February. This work may be noisy, and removal of old, creosote-coated timber piles can cause vibration and odors.
  • The main entrance to the ferry terminal is now at Madison Street. Get info about vehicle lanes for tollbooth access and ferry queuing (pdf 1mb)
  • Pedestrian connections to the Marion Street Bridge and the street remains open throughout construction to ensure access for walk-on passengers and customer safety. All facilities will be ADA-accessible.
  • The passenger-only ferry facility (King County Water Taxi and Kitsap Transit Fast Ferry) is temporarily located on the north side of Colman Dock through fall 2018.
  • Vehicle holding space off the dock is needed, especially on busy weekends and during the summer.

Terminal space limited during construction

The terminal building will be smaller as crews rebuild the dock below and the new building itself. There will not be enough space to accommodate passengers leaving for Bainbridge Island and Bremerton at the same time.

In January 2018, we adjusted the sailing schedules to and from Colman Dock to make sure there is enough room inside the terminal building to accomodate passengers waiting for one departure at at time. 

Existing terminal building open during first phase of construction in August 2017

August 2017 - February 2018

The existing terminal building remains open during first phase of construction, with no changes to current configuration. 

Nearly half of existing terminal building is demolished in March 2018

March 2018 - Summer 2019

Demolition of nearly half of the existing terminal building begins. The terminal building remains open, but it will be much smaller and have fewer amenities. 

A smaller terminal building allows crews enough room to work as safely and efficiently as possible while we maintain full ferry service.  

The smaller terminal building will maintain:

  • Ticket sales
  • ADA accessible restrooms 
  • Some seating
  • Limited food options
  • Information booth
  • Visual paging services
  • Full ferry service with no cuts to the number of sailings

Additional traveler information during this time: 

  • An attendant will be on duty in the terminal to assist people with site or other mobility challenges
  • The terminal will have a dividing rope line down the center to separate waiting areas for Bainbridge Island and Bremerton departures. The dividing rope line will have a lower and upper rope so that people with site-assist canes can locate the divider.
  • Pedestrian connections to Alaskan Way and the Marion Street Bridge remain open
  • No changes to bicycle access
  • Most vendors and all of the restaurants located inside the upper level of the terminal building will close by the end of February 2018 
  • Restaurants located at street level will remain open until summer 2019
  • No changes to vehicle access until summer 2018

Work hours

  • Monday through Saturday, 6 a.m. to 5 a.m. the following day.  There will be less construction activity inside the terminal during busy morning and afternoon commute hours. 

Noise and dust - We will work to keep the terminal building free from dust and debris, however this is an active construction zone and it is possible some dust will make its way into the public space.

  • Crews will surround the indoor active construction zones with plywood walls to keep noise and dust to a minimum 
  • Customers may hear light power tools and hammering during the day as crews remove and install turnstiles and engage in construction activity behind the plywood walls 
  • No loud work will occur inside the closed off areas between 7 a.m. and 8 p.m.
  • Loudest work will occur between 9 p.m. and 7 a.m.  
  • Contact us at or (206) 515-3870 for more information

Daytime construction activity

  • Removing and relocating turnstiles
  • Building temporary ticket window and information booth
  • Demolition work behind the temporary construction zone walls

Nighttime construction activity

  • Erecting plywood walls, demolishing sections of the building, building temporary structures inside the building

Even less space in the terminal building will be available in summer 2019.

Summer 2019

Even less terminal space is available. One-third of the new terminal building is made available for use.
