Infrastructure Upgrade for Pioneer Passage

Seattle City Light has reached a significant milestone for improvements to Pioneer Passage, an alley in Pioneer Square. Crews completed excavation and conduit installation work similar to the work that was finished in Nord Alley in 2016. Both alleys lie just east of 1st Avenue South between Yesler Way and South Jackson Street.

The work was done in conjunction with the planned repaving of the alleys using Pioneer Square Preservation Board-approved brick. The Seattle Department of Transportation will carry out that part of the work with a contractor and will keep stakeholders informed of the schedule once it is set.

City Light crews managed to minimize community impact during the construction phase by assisting businesses and tenants who accessed their garage in Pioneer Passage.

Later this year, City Light plans to return to pull new electric cable through the conduit. That work will be done at vaults and has a much smaller impact than the civil construction. Once the work is complete, customers will benefit from improved electrical reliability for years to come.

Pioneer Square’s Infrastructure and Paving Upgrade Continues in Pioneer Passage

Seattle City Light plans to replace aging underground conduit along Pioneer Passage as part of the larger infrastructure and paving upgrades taking place in Pioneer Square. The work will increase electrical reliability and capacity in the area. Seattle Department of Transportation (SDOT) and the Alliance for Pioneer Square are coordinating the project with City Light in the areas shown below:

Impacted parking and work zones shown in orange.

The work is set to begin on September 6th and continue into late November and no power outages are expected. At a later date, SDOT will repave the alley with a Pioneer Square Preservation Board-approved brick pattern. Access to the alley will be limited and one side of the alley may be partially blocked or closed during construction, but full business access will be maintained during weekdays.

Infrastructure and Paving Upgrade Planned for Pioneer Passage in Pioneer Square

Seattle City Light plans to increase reliability by replacing aging underground conduit (duct bank) and electrical cable along the Pioneer Passage alley. The alley is located east of 1st Avenue South between South Washington Street and Yesler Way. The project is being coordinated with the Alliance for Pioneer Square and the Seattle Department of Transportation (SDOT). Later in the fall, SDOT will repave the alley with a Pioneer Square Preservation Board-approved brick pattern.

See the map showing the locations and work stages.

Overview of the construction stages.

The new electrical infrastructure and equipment will increase the reliability and capacity of the Pioneer Square/downtown electrical system.

What you can expect:

  • No power outages are expected.
  • The work will proceed from south to north in stages with parking not permitted as necessary in order to stage trucks. See map.
  • Customers should expect noise caused by construction equipment during work hours.
  • Access to the alley will be limited during construction, but open after construction hours. One end of the alley at a time will be partially blocked or closed depending on which stage the crews are working in. Uniformed police officers will be on-site to help with traffic and pedestrians.
  • Trash/recycling disposal locations may need to shift to designated areas in the alley and alley deliveries should be redirected to the surrounding streets.

Construction is due to begin the first week of September and continue through November 2016, at which time SDOT will begin their paving project. Work will take place Monday through Friday, 9:00 a.m. to 3:00 p.m., and weekends from 9:00 a.m. to 6:00 p.m.
