Mile Marker was derived from the Flat Sheet Sign feature layer. This dataset contains single points representing the flat sheet signs located on interstates, ramps, state routes, TDOT maintained state park roads, and locally owned NHS routes in Tennessee. This dataset can be queried by either location information, mounting type, sign orientation, sign type, visual condition, or MUTCD code. These records were derived from vehicle mounted LiDAR sensors and digitally captured photos. This information was collected by Mandli Communications, Inc. under the direction of the Asset Management Division and the Long Range Planning Division. Questions on this dataset should be directed to TDOT.Maint.AssetManagement@tn.gov.
