As it continues to urbanize and build its consumer economies, the developing world is creating distinctive types of infrastructure. The most remarkable projects are mega-corridors — massive undertakings that link two or more megacities or regions. These are often transport-oriented developments designed to build and fortify trade connections — and stimulate new growth.
The $46 billion China-Pakistan Economic Corridor offers a cross-border example. It will physically link the two countries via a 2,000-mile network of pipelines, roads and railways, and is expected to stimulate new mega-corridor networks across Asia. China also has plans to build similar connections to other Asian markets in Asia and even to Europe. Meanwhile, several countries are expanding airports or building new ones. Two examples: the new $13 billion Beijing Daxing International Airport and the $32 billion expansion of Al Maktoum International Airport in Dubai that will allow it to accommodate more than 220 million passengers per year.
