Work planned on: Street Light Power Project near Seattle Center

Seattle City Light will convert the 480 Volt streetlight power supply along the perimeter of Seattle Center to a 120-Volt system. The existing 480 Volt lighting system is not commonly used for streetlighting by Seattle City Light and this area is one of the few remaining 480 Volt systems in Seattle.

The upgrade is happening to ensure all streetlights continue to work properly and safely to meet current standards and safety guidelines. The project improvements will consist of trenching and installing electrical conduit; installing electrical handholes; and replacing existing wiring. The project will also replace sidewalks and ADA curb ramps in locations designated on the map.

Timing and Coordination:

The conversion has been taking place around the rest of the Seattle Center perimeter as part of the overall Mercer Corridor project. This project will complete the Seattle Center perimeter streetlighting in the areas that are not included in that project. This project will start at the intersection of 1st Avenue N & Mercer St., and then wrap the perimeter of the Seattle Center campus ending at Broad St. and Denny Way. Work is expected to take place from January 2015 through June 2015.

Impacts and what you can expect:

  • Trenching in right-of-way areas
  • Sidewalk closures in locations identified on map
  • Temporary traffic restrictions in locations identified on map

No pole replacements will take place as part of this project.

Schedule: January 2015-June 2015.
Begin: January 2015
Duration: 6 Months
