There a lot of interchangeability here but here are my definitions:
Highway: high-capacity road meant to get from town to town.
Freeway: controlled-access high-speed road.
Turnpike: freeway with tolls.
Interstate: freeway with specific design standards for all US states, partially funded by federal government, designed as a nationwide network.
Expressway: a highway or freeway that’s the quick way through or around an area, with few interchanges.
