Happening now

Construction to rebuild Pier 62 began in December 2017, and is anticipated to be complete in late 2019. Visit the Pier 62 rebuild webpage to learn more about the project and what the completed pier will look like.

We’ll share regular construction updates on this webpage and via our construction updates email newsletter.

Construction update


What to expect between Virginia and Pike streets:

  • Daytime work typically 7 AM to 5 PM weekdays, Monday through Friday.
  • Periodic southbound lane closures along Alaskan Way for sidewalk work 7 AM to 3 PM. 
  • Periodic closures of westside path for pier and sidewalk work. The path will be open outside of working hours and weekends.
  • Pier 63 decking maintenance.

Beginning in late October, construction began on marine habitat enhancements just south of Colman Dock and west of Alaskan Way. The work will create an intertidal area to improve the function of the natural ecosystem along our urban shoreline. The work will have no impact to parking, pedestrians or vehicles.

Construction update


What to expect during Marine Habitat work (South of Colman Dock):

  • Rock installation on the Habitat Beach has been completed! The planting period will soon begin, but we will need to wait patiently for plants to become accustomed to the new environment over the next few years.

Columbia Street Areaway Fill

Starting in early August, areaway repair began on the north side of Columbia Street between 1st and Post avenues. This work consisted of filling the areaway under the sidewalk with lightweight concrete fill, replacing the sidewalk above and improving entryways to businesses on Columbia Street. The Columbia Street Areaway Fill was completed in mid-November. 

Additional information can be found on the Columbia Street Areaway Fill construction flyer

Early Utility Work  

Starting in lake March 2018, underground utility work began in multiple locations along the waterfront between Pike and Columbia streets, primarily in the parking area. This work was completed in late September before the travel lanes on Alaskan Way shifted to prepare for viaduct demolition in 2019. 

Additional information on Early Utility Work can be found on the Alaskan Way construction flyer, Railroad Way construction flyer, Columbia Street construction flyer, Spring and Seneca Streets construction flyer, and Madison Street construction flyer.

Harborscapes Building Removal 

Harborscapes building removal was completed in October 2018. This work had to be completed now to prepare for viaduct removal. 


A lot of construction will be happening on Seattle’s waterfront over the next several years. Working with our agency partners, we’ve created WaterfrontConstruction.org to help you stay up to date on current and future public construction in the central waterfront area.
