Most expensive rollercoaster

Expedition Everest was opened by Disney for $100 million (£;51 million) in 2006 after six years of research and construction. The concept is a train journey through the Himalayas that uses a shortcut via Forbidden Mountain, wherein lies the fearsome Yeti - an enormous 6.7-m-tall (22-ft) audio- animatronic beast controlled by 19 actuators and covered in 93 m² (1,000 ft²) of fur. The ride is located at Walt Disney World Resort at Lake Buena Vista in Florida, USA.
