Did You Know?

Infra- means "below;" so the infrastructure is the "underlying structure" of a country and its economy, the fixed installations that it needs in order to function. These include roads, bridges, dams, the water and sewer systems, railways and subways, airports, and harbors. These are generally government-built and publicly owned. Some people also speak about such things as the intellectual infrastructure or the infrastructure of science research, but the meaning of such notions can be extremely vague.
