Bay Lights Maintenance and Installation

The Bay Lights is a large-scale art installation on the western end of the Bay Bridge in San Francisco, created by artist Leo Villareal. Initially installed in 2013 to commemorate the bridge's 75th anniversary, it became a permanent feature in 2016 due to its popularity. The installation requires 25,000 LED bulbs and a dedicated team of lighting engineers for maintenance. Maintenance work is conducted at night to avoid disrupting traffic, with workers using bucket trucks and climbing the main cables to service the lights. This work is challenging and requires safety measures due to the height and complexity of the task.
