Photo of the 453 feet tall concrete mast the supports the Octavio Frias Suspension Bridge, in Sao Paolo, Brazil in South America; it is the only bridge in the world that has two curved tracks supported by a single concrete mast. There are people in the photo, but they are too far away to be recognised. Licence plates and logos on vehicles cannot be recognised as well. There is a single helicopter in the sky seen against the clouds. Photo shot in the morning sunlight; vertical format. Copy space.
