The world’s “tallest and longest tunnel slide” will open at London’s Olympic Park next year.
The ride will be built from the top of the ArcelorMittal Orbit tower and will be 178m in length and 76m wide.
It will have transparent sections so thrill-seekers will be able to see out during the £5 experience.
Speeds of 15mph will be reached during descent and the ride will last 40 seconds.
The tunnel is part of the Legacy Corporation’s commitment to developing the tower, which was designed for the London 2012 Olympics by artist Anish Kapoor and structural designer Cecil Balmond.
The Queen Elizabeth Olympic Park said: "We are delighted to announce that planning permission has been granted to build the world's tallest and longest tunnel slide from the top of the ArcelorMittal Orbit."
It said plans are now underway to install the ride which is due to completed by spring 2016.Reuse content
