Alternative Text Description for Mile Markers

TABLE OF CONTENTS

MAP OVERVIEW

This map displays the location of mile marker signs throughout the state of Florida. The map shows a comprehensive network of mile markers distributed along Florida's roadway system, derived from the FDOT Roadway Characteristics Inventory. Mile markers are represented as point features that indicate measured distances along roadways, typically used for navigation, emergency response, and roadway management purposes.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida, from the northern border with Alabama and Georgia to the southern tip of the Florida Keys. Major cities labeled on the map include Jacksonville on the northeast coast, Tallahassee in the northern panhandle, Gainesville in north-central Florida, Orlando in central Florida, Tampa and St. Petersburg on the west coast, West Palm Beach on the southeast coast, and Miami in the far south. Cape Coral is shown on the southwest coast. The map extends from Dothan, Alabama and Albany, Georgia in the north to the Straits of Florida in the south. The Gulf of America forms the western border, and the Atlantic Ocean forms the eastern border.

KEY INSIGHTS

Mile markers show extensive coverage along Florida's entire coastal perimeter, following the state's distinctive peninsula and panhandle shape. The highest concentration of mile markers appears in the southeastern region around Miami and extending through the Florida Keys, where they form a dense linear pattern. Another significant concentration occurs in the Orlando metropolitan area in central Florida. Major transportation corridors are clearly visible as continuous linear patterns of mile markers running north-south through the center of the state, east-west across the northern panhandle, and along both coasts. The distribution reveals Florida's primary highway network structure, with particularly dense marker placement in urban areas and along interstate corridors.

VISUAL ELEMENTS

Mile Markers

This layer represents the physical locations of mile marker signs along Florida's roadway system as recorded in the FDOT Roadway Characteristics Inventory.

Mile Marker Points (small red squares)

Appearance:

Small red square symbols distributed throughout the map.

Distribution:

Mile markers appear along roadway corridors throughout Florida, with coverage extending from the northwestern panhandle near Pensacola to the southernmost point of the Florida Keys.

Notable locations:

Spatial patterns:

Mile markers form clear linear patterns that trace major highway corridors. The most prominent pattern is a north-south corridor running through central Florida. Coastal routes show continuous linear distributions along both the Atlantic and Gulf of America coastlines. Urban areas display clustered concentrations with multiple parallel lines indicating complex roadway networks. The Florida Keys show a distinctive single-line pattern extending southwest from the mainland.

Overlapping Patterns

In major metropolitan areas, particularly Miami, Orlando, and Tampa, multiple roadway corridors intersect, creating areas where mile marker patterns overlap and form grid-like or radial network patterns.

SYMBOL GUIDE

ADDITIONAL INFORMATION

Mile markers serve multiple critical functions including navigation assistance for motorists, precise location identification for emergency response services, and reference points for roadway maintenance and management. The density of mile markers varies based on roadway type and importance, with major highways typically having mile markers at one-mile intervals. This map shows only the point locations of mile marker signs and does not display the actual mile marker numbers or the specific roadways on which they are located. The visualization reveals the overall structure and extent of Florida's major roadway network through the distribution pattern of these markers.

DATA CONTEXT

Data Source:

The data is derived from event mapping Feature 320, characteristic MILEMARK from the FDOT (Florida Department of Transportation) Roadway Characteristics Inventory. This inventory represents field-collected information about roadway features maintained by FDOT. Data source layer name: MILEMARKERS_OCT25.

Definition Query:

No definition query or filter criteria was applied. The map shows all available mile marker locations from the dataset.

Scale Information:

The map is displayed at a statewide scale showing the entire state of Florida. At this scale, individual mile markers appear as small symbols, and the map is appropriate for understanding overall network distribution and major corridor patterns rather than identifying specific mile marker locations.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087).

Time Period of Content:

The data represents the most recent inventory performed as of October 2025.

Limitations:

The data represents information as collected and reported during the most recent inventory and may not reflect current conditions. Changes such as new roadway construction, roadway modifications, or addition or removal of mile marker signs that occurred after the inventory date would not be reflected in this dataset.

Map Coverage:

The map covers the complete geographic extent of the state of Florida, including the mainland peninsula, the panhandle region, and the Florida Keys island chain. Portions of neighboring states (Alabama and Georgia) and adjacent waters (Gulf of America and Atlantic Ocean) are shown for geographic context but contain no data.
