<div style='text-align:Left;'><div><div><p><span>The Road Segment table describes the administration and ownership of the segment of road. It contains tabular polyline data showing the log miles/measures, road name, functional class, government control, and U.S. Routes. Road names are derived from visual surveys by field crew or official GIS maps. Functional class is set by the Federal Highway Administration (FHWA). All other categories are determined by state and local agencies. This dataset is updated weekly. </span></p><p><span style='font-weight:bold;'>County</span><span> – County in Tennessee where associated features and attributes are located.</span></p><p><span style='font-weight:bold;'>Route Number</span><span> – Route in Tennessee with corresponding attributes.</span></p><p><span style='font-weight:bold;'>Special Case </span><span>– Route designator for non-standard routes such as By-Pass.</span></p><ul><li><p><span>00 None</span></p></li><li><p><span>01 Spur - S</span></p></li><li><p><span>02 Alternate - A</span></p></li><li><p><span>03 State Connector - C</span></p></li><li><p><span>04 Bypass - BP</span></p></li><li><p><span>05 Business Route - BR</span></p></li><li><p><span>06 Northbound - N</span></p></li><li><p><span>07 Southbound - S</span></p></li><li><p><span>08 Eastbound - E</span></p></li><li><p><span>09 Westbound - W</span></p></li></ul><p><span style='font-weight:bold;'>County Sequence </span><span>– This number indicates the sequential number of times a route enters and leaves the county, begins with zero (0).</span></p><p><span style='font-weight:bold;'>Beginning Log Mile (BLM)</span><span> – The beginning log mile (measure) for the route segment.</span></p><p><span style='font-weight:bold;'>Ending Log Mile (ELM) </span><span>- The ending log mile (measure) for the route segment.</span></p><p><span style='font-weight:bold;'>Functional Classification </span><span>– These codes, set by the FHWA, provide a statewide highway functional classification in rural and urban areas to determine functional usage of the existing roads and streets.</span></p><ul><li><p><span>01 Rural Interstate</span></p></li><li><p><span>02 Rural Other Principal Arterial</span></p></li><li><p><span>03 Rural Freeway or Expressway</span></p></li><li><p><span>06 Rural Minor Arterial</span></p></li><li><p><span>07 Rural Major Collector</span></p></li><li><p><span>08 Rural Minor Collector</span></p></li><li><p><span>09 Rural Local</span></p></li><li><p><span>11 Urban Interstate</span></p></li><li><p><span>12 Urban Freeway or Expressway</span></p></li><li><p><span>14 Urban Other Principal Arterial</span></p></li><li><p><span>16 Urban Minor Arterial</span></p></li><li><p><span>17 Urban Collector</span></p></li><li><p><span>19 Urban Local</span></p></li></ul><p><span style='font-weight:bold;'>Government Control</span><span> – These codes determine ownership and maintenance responsibility.</span></p><ul><li><p><span>01 State Highway Agency</span></p></li><li><p><span>02 County</span></p></li><li><p><span>04 Municipal</span></p></li><li><p><span>11 State Park</span></p></li><li><p><span>12 Local Park</span></p></li><li><p><span>21 Other State Agency</span></p></li><li><p><span>25 Other Local Agency</span></p></li><li><p><span>26 Private</span></p></li><li><p><span>27 Railroad</span></p></li><li><p><span>40 Other Public</span></p></li><li><p><span>60 Other Federal Agency</span></p></li><li><p><span>63 US Fish and Wildlife</span></p></li><li><p><span>64 US Forest Service</span></p></li><li><p><span>66 National Park Service</span></p></li><li><p><span>67 TVA</span></p></li><li><p><span>68 Bureau of Land Management</span></p></li><li><p><span>70 Corps of Engineers (Civil)</span></p></li><li><p><span>72 Air Force</span></p></li><li><p><span>73 Navy or Marines</span></p></li><li><p><span>74 Army</span></p></li><li><p><span>80 Other</span></p></li></ul><p><span style='font-weight:bold;'>US Route Number </span><span> – US Route Number assigned to roadway segment.</span></p></div></div></div>
