Federal Aid Highway System TDA

The FDOT GIS Federal-Aid Highway System feature class shows Federal aid funding eligibility of public roadways. It also designates roadways as on or off the National Highway System (NHS). If code 5 appears in this characteristic, then the roadway is on NHS, otherwise it is off NHS. NHS is assigned by Transportation Data & Analytics and approved by the FHWA. All roadways functionally classified as major collector and above and not NHS are Surface Transportation Program (STP). In general, STP projects may not be on local or rural minor collectors. To be eligible for federal STP funding, a project must be on a roadway functionally classified as an urban collector or rural major collector or above, or on a local road or rural minor collector if that roadway was on the Federal-aid Rural Secondary System (FARSS) as designated on January 1, 1991. Federal aid eligibility may include designation of the NHS. This information is required for all roadways functionally classified as local and above, and NHS roadways with any functional classification. 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/fahwysys.zip' target='_blank' rel='nofollow ugc noopener noreferrer'>https://ftp.fdot.gov/file/d/FTP/FDOT/co/planning/transtat/gis/shapefiles/fahwysys.zip</a><br /><br /></div><div><img alt='FDOT Logo' src='https://fdot.maps.arcgis.com/sharing/rest/content/items/d9f87eaf6b4d4cb0904bc07ef26bd549/data' /></div>
