State highways are the primary and secondary roads that link cities within a state. Each state is responsible for route numbering and layout, so routes can vary from state to state.
The default marker for state highways is a white circle with a black number, but each state is free to choose a different marker. Many states have chosen a design theme relevant to the state, such as an outline of the state itself, to distinguish state route markers from interstate, county, or municipal route markers.
State highways are an important part of the transportation system in the United States. They provide a way for people to travel between cities and towns, and they also help to connect rural areas to the rest of the country.
