Interstates TDA

The FDOT GIS Interstates feature class provides spatial information on Florida Interstate highways. The interstate and US route numbers are assigned by the Federal American Association of State Highway and Transportation Officials (AASHTO) usually following recommendations by the each state department. Both interstate and US routes are coded under the USROUTE characteristic. Interstate numbers are assigned with even numbers for west to east routes and odd numbers for routes going south to north, starting with the lowest number in the lowest part of the nation and progressing higher nationwide. US route numbers are assigned with odd numbers for north and south routes with the low number beginning in the east and progressing higher toward the west. This numbering practice is used across all states for all interstates and US routes for the public traveling purposes. This information is required for roadways functionally classified as principal, minor arterials that have US route designations, and all Active Exclusive roads that are associated with Interstate and the US route. This dataset is maintained by the Transportation Data & Analytics office (TDA).<span style='font-weight:bold'> The source spatial data for this hosted feature layer was created on: 06/27/2026</span>.<br /><br />For more details please review the <a href='https://www.fdot.gov/statistics/rci/default.shtm' target='_blank' rel='nofollow ugc noopener noreferrer'> FDOT RCI Handbook </a><div><br />Download Data: <br /> Enter Guest as Username to download the source shapefile from here: <a href='https://ftp.fdot.gov/file/d/FTP/FDOT/co/planning/transtat/gis/shapefiles/interstates.zip' target='_blank' rel='nofollow ugc noopener noreferrer'>https://ftp.fdot.gov/file/d/FTP/FDOT/co/planning/transtat/gis/shapefiles/interstates.zip</a><br /><br /></div><div><img alt='FDOT Logo' src='https://fdot.maps.arcgis.com/sharing/rest/content/items/d9f87eaf6b4d4cb0904bc07ef26bd549/data' /></div>
