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.
- Alaskan Way traffic shift prep work between Pine and Union streets:
- The crosswalk at Pike Street will close Saturday, October 13, and reopen by Monday, October 15. During the closure, pedestrians will be detoured one block south to Union Street.
- When Alaskan Way reopens on Sunday, the road will be one lane between Pine and Union streets, with two-way traffic controlled by flaggers.
- By Monday morning, October 15, one lane in each direction will open while signal and utility work continues.
- In late November, two lanes will be open in each direction.
Starting in late March, underground utility work began in multiple locations along the waterfront between Pike and Columbia streets, primarily in the parking area. This work must be completed now before the travel lanes are shifted this fall to prepare for viaduct demolition in 2019.
Early Utility Work is complete:
- In late September, we completed Early Utility Work, by finishing up the installation of an electrical vault between Seneca and Spring streets.
- This work had to be completed now before the travel lanes on Alaskan Way are shifted to prepare for viaduct removal.
Other area projects:
- Alaskan Way traffic switch: Alaskan Way will be closed from 8 PM Saturday, October 13 to 10 AM Sunday, October 14. During this closure, crews will complete striping and activate signals in order to open Alaskan Way in its new, four-lane alignment west of the viaduct. Visit the AWV Program website for a map of the new alignment and additional details.
- Center City Connector: Please see the project website for more information
- Private utility work: Private utility companies continue relocation work in preparation for viaduct removal. Expect work in various locations along the waterfront between South King and Pike streets, 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.
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.
Starting in early August, areaway repair will begin 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.
What to expect on Columbia Street:
- Construction work will occur Monday through Friday, 7 AM to 5 PM.
- Columbia Street closed between First and Post avenues.
- Pedestrian detours continue in the vicinity of Post Avenue and Alaskan Way.
Where to expect Columbia Street construction:
Harborscapes building removal was completed in October 2018. This work had to be completed now to prepare for viaduct removal.
Beginning in October, construction will begin 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.
What to expect during Marine Habitat work (South of Colman Dock):
- All work will be performed from the water.
- Construction will occur Monday through Friday, 7 AM to 7 PM, and Saturday, 9 AM to 7 PM, with occasional night and weekend work.
- Equipment may be noisy; the most significant noise coming from barge mounted equipment
