Story behind the photograph
This Sunday 18th of March was the Sydney Harbour Bridge 75th anniversary. The day was celebrated by closure of the bridge to general traffic and allowing hundreds of thousands of people to take a walk across the bridge from North Sydney into the city. There were a lot of events both on water and in the air showing a spectrum of historical vessels and aircraft from 1920s to today. At night the organisers have created a visual spectacle by directing strong colour light beams underneath the bridge structure highlighting its engineering elements. You can see more photographs from the day in the Sydney Harbour Bridge 75th Anniversary gallery.
