Chinatown-ID Underdeck LED Lighting Upgrades

Map showing locations of Chinatown-ID underdeck LED lighting upgrades

Project Description

Seattle City Light plans to upgrade the underdeck high pressure sodium (HPS) light fixtures at several overpass locations in the Chinatown-International District area. Existing lights will be replaced with new light emitting diode (LED) fixtures.

Location

This project is located on South Jackson and King streets in the Chinatown-International District neighborhood.

What's Happening Now?

Project Update (Feb. 2021): Crews are working through some remaining electrical issues before the new streetlight system can be powered.

Community Benefits

  • The new lights will increase visibility and improve pedestrian and traffic safety in the Chinatown-International District.
  • The installations will lower operations and maintenance costs for the utility.
  • LEDs reduce greenhouse gas emissions during manufacturing as well as when they are in use. Additionally, about 20,000 tons of reduced carbon emissions per year are the result of fewer service vehicle trips.

Anticipated Impacts

  • Crews will replace the existing lights with new LED fixtures that focus on sidewalk and roadway lighting. The color temperature for the new lights will be at 4000 Kelvin (K), which emits a warm white color.
  • Maintenance outages may be required to do the work safely. Customers will be notified in advance of any outage.
  • Customers can expect temporary parking and lane restrictions in the immediate work area during construction hours.
  • Traffic control flaggers will be used to maintain traffic and pedestrian safety through the work areas.
  • Noise is expected from construction and heavy equipment.

  • Construction Start: June 2020
  • Duration: 3-4 months
  • Daily Work Schedule: Mon-Fri: 9 a.m.-3 p.m. Some weekend work is expected.
