Washington State Ferries is reminding drivers who travel through Colman Dock to give themselves more time to get to and out of the Seattle terminal in the coming weeks.

Contractor crews for the Washington State Department of Transportation will begin deconstructing the section of the old Highway 99 Alaskan Way Viaduct in front of the terminal on Wednesday, Feb. 20.

Officials said the work will require reducing Alaskan Way to one lane in each direction between Marion Street and Yesler Way. Travelers should prepare for heavier-than-normal traffic congestion during the closure. The work is scheduled to conclude by the end March.

Construction is not anticipated to affect walk-on passengers’ access to Colman Dock, officials added.

Customers will still be able to use the Marion Street pedestrian bridge or Alaskan Way to access the terminal.
