The final piece of the world’s tallest and longest tunnel slide has been lifted into at the Orbit tower at the Queen Elizabeth Olympic Park.

The 178m slide, designed by artist Carsten Höller, is set to open to the public on Friday, June 24, after the thirtieth and final section of tunnel was lifted into place this week.

During the 40-second trip, riders will reach speeds of up to 15 miles per hour, with London’s skyline visible through transparent sections of the tube.

Peter Tudor, Director of Visitor Services, London Legacy Development Corporation, said: “It’s so exciting that the final piece has been lifted into place.

“The Slide at the ArcelorMittal Orbit will be an incredible experience and yet another reason to visit Queen Elizabeth Olympic Park. I can’t wait until it opens on 24 June.”

Entry to the tower and The Slide will cost £17 for adults, or £12 for children, with a £2 discount for local residents.

During the 40-second trip, riders will reach speeds of up to 15 miles per hour, with London’s skyline visible through transparent sections of the tube.

The Orbit is Britain’s largest piece of public art. The 376-foot tower was completed in May 2012 and was largely funded by steel tycoon Lakshmi Mittal.

Plans were announced in July 2015 to construct a slide at the tower, in a bid to attract additional visitors.
