The US highway numbering system is a standardized method for designating different routes through the country. It's a system developed by the American Association of State Highway and Transportation Officials (AASHOT). This organization assigns a unique number to each highway, indicating the direction and the stage of development. For instance, highways labeled with odd numbers run north-south, while even ones go east-west. Interstate highways have a distinctive "X" added after their number (i.e., I-90). Primary highways are typically assigned numbers below 100, while routes that branch off from the primary routes use numbers between 100 and 999, depending on their status and the state.
