Question

What is meant by a state's infrastructure?

Answer 1

It means the things that help the city run, like resources.

Answer 2

Infra- means "below;" so the infrastructure is the "underlying structure" of a country, state, etc. 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.
