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.

Conduit with shoring


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.
