Each U.S. state has a specific state highway system. State highways follow different quality levels and standards. Some of them are so intensely used they become Interstate highways while others are roads of low quality with little traffic.
They are officially called state routes, state highways or simply state roads, depending on the state in question. Some U.S. states design their highway signs including its geographic shape (like Arizona, South Dakota or Ohio), some other state symbol such as the flag (like Colorado) or its official flower (like Kansas), and even its name’s origin (like Washington with the bust of George Washington). However, most of them are rectangular, round or adopt another generic form.
Our collection of state highway signs here is still incomplete but we offer you already at least one road sign for every state and the shield for all state highways longer than 150 miles in the whole of the United States. In total, 483 state highway signs, which makes it our second biggest sign set after Interstates.
