infrastructure (n.)
“the underlying structure of a society or other organization,” is used today particularly to designate the roads, bridges, schools, sewers, electrical installations, and other structural systems that make possible a complex urban society. The term has come close to being a cliché; use it as precisely as possible, and avoid figurative uses that may blur its distinctive qualities.
