A visual representation of the island chain extending southwest from the tip of Florida, often incorporates numerical indicators denoting distances along the primary roadway. These numerical references, typically sequential, provide location context for navigation and orientation throughout the archipelago. This type of cartographic aid assists travelers in pinpointing specific destinations, landmarks, or points of interest along the Overseas Highway.
This resource facilitates efficient travel planning and enhances situational awareness. The numbered markers serve as a constant reference point, reducing uncertainty and aiding in emergency response by enabling precise location reporting. Historically, this system evolved alongside the development of the Overseas Highway, providing a standardized method for referencing locations in a region characterized by fragmented landmasses and extensive waterways.
