Construction of the new airport was only part of the Airport Core Programme, which also involved construction of new road and rail links to the airport, with associated bridges and tunnels, and major land reclamation projects on both Hong Kong Island and in Kowloon. The project is the most expensive airport project ever, according to Guinness World Records. Construction of the new airport was voted as one of the Top 10 Construction Achievements of the 20th Century at the ConExpo conference in 1999
