Bay Bridge’s Lights Return After Being Shut Off for 3 Years

The original installation of the lights opened in 2013 but closed in 2023 after wear from wind, salt, moisture, and vibration led to LED failures.

The San Francisco-Oakland Bay Bridge lights returned Friday night after being shut off for three years.

The event debuted the 1.8-mile-long rebuild that features 48,000 custom-engineered LEDs, according to Illuminate, the San Francisco nonprofit arts organization that produced the project. The lights will be on every night from sunset until sunrise.
