The 543m and 7,000 tonne south approach viaduct was the first real glimpse of the bridge to appear, as enormous steel box girders were launched out into the Forth across the distinctive V-shaped support piers.

Not all of the south viaduct’s seven V-shaped piers share the same foundations, with three piers located on land and four piers in the water.
