Current work zones

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:

  • Work hours are typically 7 AM to 7 PM on weekdays and 9 AM to 7 PM on Saturdays with occasional work until 10 PM on any of those days, if needed.
  • Pile installation continues. Increased noise can be expected.
  • Expect intermittent pedestrian path closures and detours for safety on the west side trail during pile installation.
  • Road restoration work continues. There will be periodic closures of the Pike Street crosswalk.

Starting in early August, areaway repair began on the north side of Columbia Street between 1st and Post avenues. This work consists of filling the areaway under the sidewalk with lightweight concrete fill, replacing the sidewalk above and improving entryways to businesses on Columbia Street.

Construction update


What to expect on Columbia Street:

  • Work at the marine habitat south of Colman Dock is in full swing.
  • Finishing touches, including minor furnishings, will be installed early next week in front businesses on the north side of the sidewalk.
  • Private utility work continues near Post Avenue at Columbia Street.
  • Potholing work on Columbia Street between Western Avenue and Alaskan Way continues.

Where to expect Columbia Street construction:

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, and Saturday, 9 AM to 7 PM, with occasional night and weekend work.
  • All work will be performed from the water.
  • Expect some construction equipment and vehicles moving in and out of Pier 48. 
  • Equipment may be noisy; the most significant noise coming from barge mounted equipment.

Step Forward, the tunnel grand opening celebration  

On Feb. 2-3, WSDOT and the City of Seattle are hosting a grand opening celebration to mark the completion of the new SR 99 tunnel, the final days of the viaduct, and the improved and reconnected waterfront to come. The family-friendly event will include a free walk in the new SR 99 tunnel, a community celebration on the viaduct, plus food trucks and live music. There will also be an 8k fun run and a 12-mile bike ride that traverse both the viaduct and the new tunnel. Visit www.99stepforward.com for more information.

Private Utility Work

Private utility companies continue relocation work in preparation for viaduct removal. Expect work along the waterfront near Union, South Main, and South Washington streets. Work will be primarily in small areas, and with relatively short durations of single-lane closures and localized parking restrictions. Click here to see a map of the private utility work in the area. For questions about a specific location, contact: SDOTConstructionHub@seattle.gov.

  • Trenching and overhead utility pole work from King to University streets along Alaskan Way will start the week of November 12.

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.
