Here’s a heads up for what promises to be a stunning addition to the Bay Area cityscape. On March 5, in honor of its 75th anniversary, the bay bridge will be lit with 25,000 white LED lights. Each light is individually programmable by the artist behind The Bay Lights project, Leo Villareal, to create complex algorithms and patterns for a dazzling display across the bridge’s west span (the east span will come later). Villareal said it will incorporate 255 levels of brightness, and the lights will be sequenced so the bridge mirrors its surroundings.

The project will continue for two years, with nightly lighting from dusk to midnight. And because it uses energy efficient LEDs, the cost of lighting bridge should be just $30 per day, while it’s estimated to bring an added $97 million to the local economy.
