Transport
To link the vast territory together, America has
constructed the very convenient super highway system. The national transport
system mostly depends on those super highways. There are also transportation
systems in big cities; the subway system in New York is the biggest one.
But generally, the public transport in America is comparatively inferior
to other developed countries. People usually travel in their own cars.
Airline is the best way for long distance travel. 17 out of the world’s
busiest airport are in the US.
