The aerial view of the bridge a scene like never before with freshly laid grass, grazing cows and hundreds of families enjoying a picnic breakfast.
The forecast rain was thankfully held off and people turned out to enjoy croissants, sausages, bacon eggs and coffee - with a stunning view across the water to the Opera House.
Many who were not among the lucky ticket-holders drawn from a ballot of 190,000 people to take part in the unique gathering still turned up at each end of the bridge.
