What does insterstate mean?

An "interstate" typically refers to a highway or a road that crosses state boundaries, connecting different states within a country. In the United States, for example, the Interstate Highway System is a network of controlled-access highways that spans the nation, facilitating long-distance travel and commerce between states.

They are maintained by state and federal governments and play a crucial role in transportation infrastructure
