Qatar's construction plans include a $36 billion rail system, a new airport that will cost $17.5 billion, a $7.4 billion seaport, hundreds of kilometres of major new roads, and an overall urban makeover. Many of the projects will prepare the country to host the 2022 World Cup soccer tournament, which the government hopes will seal Qatar's arrival as a top global travel destination.
