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 Spring streets:

  • Day time work hours are typically 7 AM to 7 PM on weekdays and 9 AM to 7 PM on Saturdays as needed.
  • Pile driving continues.
  • Periods of increased noise and vibration associated with vibratory and impact hammers.

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):

  • Construction will occur weekdays, 7 AM to 7 PM.
  • Intermittent night work continues. Work hours are 7 PM to 4 AM. The noisiest work will be complete by 10 PM.
  • Equipment may be noisy during daytime work, with the most significant noise coming from barge-mounted equipment.

Full Realign99 highway closure begins Friday! 

 WSDOT will have daily updates on the closure starting Monday. WSDOT is expecting significant congestion during commute periods, both on highways and local streets. Follow your local traffic reports or #realign99 on Twitter as you plan your trips. 

Private Utility Work

Private utility companies continue relocation work in preparation for viaduct removal. Remaining work locations are focused at the Pike Street Hill Climb, University, Spring, and South King streets and aerial work along the west side of Alaskan Way. Some of the work will be performed at night to limit traffic impacts. See the map of the private utility work in the area. For questions about a specific location, contact: SDOTConstructionHub@seattle.gov. 

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.
