At Sydney's New Year's Eve fireworks, which famous bridge is used as a central backdrop?

Sydney's New Year's Eve fireworks use the Sydney Harbour Bridge as a central backdrop.

The bridge spans Sydney Harbour between the central business district and the North Shore. Its steel arch and location beside the Opera House make it a highly recognizable structure for the city's annual celebration, which is watched by large crowds around the harbour and by international television audiences.

Sydney's festivities usually include an earlier family-oriented display and a major midnight fireworks show. The program can also feature aerial effects launched from barges, buildings, and other harbour structures, so the bridge is a centerpiece rather than the only launch site.

The bridge is sometimes incorrectly described as the Harbour Bridge in Melbourne or confused with Sydney Opera House. Its official name is Sydney Harbour Bridge, and it opened to traffic in 1932. The New Year's Eve event is organized as a large harbour-wide celebration rather than a ceremony limited to the bridge itself.
