Bainbridge Ferry Terminal Overhead Walkway December update

Aerial view of construction progress at Bainbridge Island ferry terminal

Crews continue pile-driving work at the Bainbridge ferry terminal through December. This aerial shot from December gives a good overview of the project status.

Pile driving for passenger walkway extends through December 

Whenever we work below the water line, state law requires us to monitor marine life in the area. Recently we detected surf smelt eggs near where crews were set to drive piles. Crews paused work there for two weeks as we monitored the eggs. This means pile driving will continue through December. We will continue to monitor marine life throughout the project.

Both vibratory and impact hammers are used to drive the piles. To reduce noise for ferry passengers during impact hammering, crews carry out this work between sailings. Even so, there can be more noise and dust in the area along with the possibility of creosote smell as the old piles are pulled and hauled away.

These changes continue through December:

  • Slip 2 continues as the primary slip. 
  • Vehicle exit lanes continue to be realigned. 
  • Vehicles are held in lanes 1-15 in the upper holding area.
  • Motorcycles stage in the lower trestle lane 5 and bicycles in lane 6.

Changes at Seattle terminal starting Dec. 12

Aerial views of slips at Colman Dock

This view shows the slips serving Colman Dock. Slip 1 is on the far right and slip 3 is at far left.

Walk-on passengers have had more room to spread out in our spacious new passenger terminal that opened Nov. 18 along with great views through the large windows looking out onto Elliott Bay and downtown Seattle. This is one part of the project. Crews continue work on the entry building and elevated pedestrian walkway that links it to the terminal building.

As with any construction project of this size, crews are still working throughout the site. That means changes to slip assignments starting Dec. 12 to allow crews finish electrical work to the slips and make concrete repairs to the south balcony.  

Bainbridge walk-on passengers exiting from slip 2 need to head north (turn left) after disembarking the ferry walkway onto the balcony to exit around the north balcony of the terminal building.

Here’s an overview of the work to come. But it’s important to sign up for rider alerts for the route and follow staff direction as this work may wrap up earlier or later than stated here.   

  • Slip 1 closure starting Dec. 12 for electrical work. This is expected to last three weeks. This moves Bainbridge service to slip 2 for that time. Note: Crews will also be working from an in-water derrick barge in slip 1 on starting Dec. 12.
  • Southwest corner of balcony closes Dec. 12 for concrete work. This is expected to last two weeks. All walk-on passengers must exit around the north balcony of terminal building (see photo above).
  • Slip 2 closure starting around Jan. 3 and lasting for about two weeks. Bainbridge service moves back to slip 1.
  • Marion Street exit closures through December during these hours: 6:30 a.m. to 9:30 a.m. all traffic must exit via Yesler Way. From 9:30 a.m. to 2:30 p.m. Marion exit is down to a single lane. Reminder that large trucks must use the Yesler Way Exit.
