The Bay Bridge — San Francisco's lesser-known bridge — got a 1.8-mile-long, 50-foot-high "light sculpture" Tuesday night.
The display includes 25,000 LED lights and will be up for at least two years, according to a statement.
The lights cost $4.25 an hour to operate and were funded entirely by private donations.
California Lt. Gov. Gavin Newsom, former San Francisco mayor, said he liked the lights.
