The airport has an advanced highway and railway system linking it to the city centre of Hong Kong. The building project was one of the largest in the world, and featured in Discovery Channel's "Ten Greatest Modern Projects of the World". It was designed by the famous architect, Norman Foster. The aim of the airport was to increase traffic and capacity which the old Kai Tak Airport could not handle. It remains one of the best airport in the world, along with Singapore's Changi Airport and Seoul's Incheon International Airport.
