Denny Substation Project
Pay My Bill   

The Denny Substation Program is transitioning into the final phase of construction. Over the next several weeks, a series of tasks will continue around the substation site including utility and material testing, vault work, asphalt grinding and overlay, decorative lighting installations and testing, safety testing for guardrails, caulking, painting, sign installations, plumbing, landscaping, and irrigation. As soon as mid-March, we’ll begin installations on two artwork pieces: Lead Pencil Studio’s work called “Transforest” which is a large-scale sculpture on the southwest side of the substation, and Ned Kahn’s “Switchwall” work which is integrated into the outer walls of the substation facility at the upper southeast and northeast corners.

Denny Network

The Denny Network will be working on a series of small unscheduled weather dependent items. The following work will take place when the streets are expected to be dry:

  • Vault inspection and remediation
  • Asphalt paving
  • Roadway channelization (street striping and other markings)

Additionally, City Light crews will continue work in South Lake Union installation of new electrical cable and equipment in recently completed Denny Network infrastructure.

What to Expect During Network Construction

  • Closures of sidewalks and crosswalks should be expected in work areas
  • Business and pedestrian access will be maintained wherever possible
  • Lane restrictions and some traffic and pedestrian detours
  • Typical weekday work hours from 6 a.m. to 7 p.m.
  • Some weekend, night, and early morning work
  • Noise and vibrations during high-impact work
