On Thursday night, the Fremont Bridge will fire up its new lights, a permanent art installation celebrating the centennial of Seattle’s historic bascule bridges. The Ballard and University bridges are next on the list.

The Bridge Lights project is a collaboration between SDOT, the Office of Arts and Culture and artists Hayley Buckbee and Ian Campbell (with RSVR). The city says the lights are designed to “gently reflect seasonal, solar and lunar patterns,” and the Fremont design “beautifies this city landmark and celebrates the vibrant artistic spirit of the Fremont community.”

Unlike most major U.S. cities, Seattle’s bridges lack artistic light, the city said. “Lighted bridges serve as symbols of local pride for residents and become a significant part of a city’s story, attracting regional visitors and tourists, like other city landmarks including the Fremont Troll and the Space Needle,” SDOT explained in a press release.

This Wednesday evening, the city will provide a 6-minute preview of the lights (“including four seasonal palettes”) for the media, sometime between 6:30 and 7 p.m. Then on Thursday evening, the light display switches on permanently.

SDOT tells My Ballard they don’t have a date set for the Ballard Bridge lights as of yet, and it’s “not in the immediate future.”
