State highways are major roads that connect cities and towns within a specific state. They are maintained by the state government and are essential for transportation, commerce, and travel. These highways often link to local roads and can vary in size and capacity, accommodating different types of vehicles. Typically marked with a unique numbering system, state highways are designed to facilitate efficient movement across the state. They may include features like interchanges, traffic signals, and rest areas. State highways play a crucial role in the overall transportation network, supporting both local and regional connectivity.
