SAN FRANCISCO - After more than 75 years in the shadow of its glamorous cousin, San Francisco's "other" bridge is getting a chance to shine.

A New York artist has turned the San Francisco-Oakland Bay Bridge into his latest -- and by far biggest -- canvas.

Leo Villareal has individually programmed 25,000 white lights spaced a foot apart on 300 of the span's vertical cables to create what is being billed as the world's largest illuminated sculpture. Villareal is scheduled to flip the switch on it with a click of his laptop computer on Tuesday night.

The work, entitled "The Bay Lights" uses sequences of shifting light to produce an array of abstract patterns that will be visible nightly for at least the next two years.
