Alternative Text Description for SIS Highway Map

TABLE OF CONTENTS

MAP OVERVIEW

This map displays the Strategic Intermodal System (SIS) Highway network across the state of Florida. The SIS Highway layer shows major transportation corridors that form Florida's strategic highway infrastructure. The map provides a statewide view of these critical transportation routes and their geographic distribution throughout the state.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida, extending from the Florida Panhandle in the northwest to the Florida Keys in the south. Major cities labeled on the map include Jacksonville in the northeast, Tallahassee in the Panhandle, Orlando in central Florida, Tampa on the west coast, and Miami in the southeast. Other visible cities include Savannah (Georgia) to the north, Albany and Valdosta (Georgia) to the northwest, Dothan (Alabama) to the far northwest, Gainesville in north-central Florida, Palm Coast on the northeast coast, St. Petersburg and Cape Coral on the west coast, and Melbourne and Palm Bay on the east coast. The map shows Florida bordered by the Atlantic Ocean to the east, the Gulf of America to the west and south, and Georgia and Alabama to the north.

KEY INSIGHTS

The SIS Highway network forms a clear skeletal framework connecting Florida's major urban centers and regions. The highest concentration of SIS highways appears in the Jacksonville, Orlando, Tampa, and Miami metropolitan areas, with dense networks of interconnected routes. Major corridors run north-south along both coasts and through the center of the state, while east-west corridors connect the coasts across the peninsula and through the Panhandle. The network demonstrates hub-and-spoke patterns radiating from major urban centers, with particularly notable concentrations in northeast Florida around Jacksonville and in southeast Florida around Miami. The Panhandle region shows a distinct east-west corridor pattern with branching routes extending southward.

VISUAL ELEMENTS

SIS Highway Network

The Strategic Intermodal System (SIS) Highway network consists of black linear features representing major highway corridors throughout Florida.

SIS Highway Routes (black lines)

Appearance:

Black solid lines of consistent width displaying highway routes throughout the state.

Distribution:

SIS highways are distributed across the entire state of Florida, with coverage extending from the western Panhandle to the southern tip of the peninsula and the Keys.

Notable locations:

Dense networks appear in Jacksonville, with multiple routes converging in the metropolitan area. Orlando shows a significant concentration with routes radiating in multiple directions. The Tampa Bay area displays interconnected highway routes. The Miami metropolitan area in southeast Florida shows the densest concentration of SIS highways. Additional concentrations appear in Tallahassee, Gainesville, and along major coastal corridors.

Spatial patterns:

The network exhibits clear north-south corridors running parallel to both the Atlantic and Gulf of America coasts. Central corridors run through the interior of the peninsula connecting northern and southern regions. East-west routes traverse the peninsula connecting coastal regions, particularly visible in central and northern Florida. In the Panhandle, a dominant east-west corridor extends from Tallahassee westward with perpendicular branches. Radial patterns emanate from major urban centers, creating hub-like configurations. Linear corridors follow the general shape of the peninsula, with routes extending into the Keys in the far south.

Overlapping Patterns

Multiple SIS highway routes converge and overlap in major metropolitan areas, creating concentrated nodes of connectivity at Jacksonville, Orlando, Tampa, and Miami. These convergence points serve as major hubs where multiple strategic corridors intersect.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map focuses exclusively on the SIS Highway layer, showing the strategic highway infrastructure without other transportation modes or features. The Strategic Intermodal System represents Florida's most critical transportation facilities that are essential to the state's economy and mobility. Base map features such as city labels and state boundaries are included for geographic reference and orientation but are not part of the thematic SIS Highway layer. The uniform symbology indicates that all displayed routes are designated as SIS highways, without differentiation by classification or hierarchy within the system.

DATA CONTEXT

Data Source:

The data represents Florida's officially designated Strategic Intermodal System highways. Data source layer name: SIS_HIGHWAY_JAN25.

Definition Query:

No definition query or filter criteria was applied. The map displays the complete SIS Highway network.

Scale Information:

The map is displayed at a statewide scale showing the entire state of Florida and portions of neighboring states. This scale is appropriate for viewing the overall network structure and major corridors of the SIS Highway system.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The data is current as of January 2025, as indicated by the data source layer name.

Limitations:

At this statewide scale, individual highway route numbers and detailed local connections may not be visible. The map shows designated SIS highways but does not display non-SIS roads or other levels of the highway network.

Map Coverage:

The map extends beyond Florida's borders to show portions of southern Georgia and southern Alabama for geographic context. The primary focus is the complete state of Florida from the western Panhandle through the peninsula to the Florida Keys.
