It was so singular a marvel, so ambitious a feat, that its opening drew the president and a crowd of thousands. A leading national magazine said it stood poised to become "our most durable monument."

Some 125 years later, the Brooklyn Bridge remains a powerful symbol of engineering might and imagination, and a revered fixture in the landscape of the nation's largest city.

And it can still draw a crowd. Thousands of people are expected at the bridge's 125th birthday blowout Thursday, with fireworks, a Navy flyover, a colorful new lighting scheme and the debut of a tribute song scheduled to honor the storied span. It opened on May 24, 1883.
