Thirty separate sections comprise the Slide's snaking form, which twists itself around the sculpture's latticed structure. Measuring 178 metres in length, it claims to be "Europe's tallest and longest tunnel slide".
Beginning from the 76-metre-tall viewpoint, Höller's slide spirals downwards in a tight corkscrew before unravelling 50 metres from the ground. Riders can expect to reach speeds of 15 miles per hour during their 40-second descent.
The tube has a predominantly silver base but features a transparent top half, offering panoramic views of London's skyline to thrill seekers.
Visitors ascend the steel tower via a central elevator to reach the slide or viewing deck above.
The ArcelorMittal Orbit was created by artist Anish Kapoor and structural engineer Cecil Balmond as a key attraction for visitors during the 2012 Olympics. It is located in the Queen Elizabeth Park in east London, standing 114.5 metres tall – the tallest sculpture in the UK.
"It's so exciting that the final piece has been lifted into place," said Peter Tudor, a spokesperson from London Legacy Development Corporation. "The Slide at the ArcelorMittal Orbit will be an incredible experience and yet another reason to visit Queen Elizabeth Olympic Park."
