What this tracks
This dataset records the location and type of pavement markings (like lane lines and crosswalks) on interstates, state routes, and select locally maintained roads in Tennessee.
Why it matters to you
If you’re planning a road trip through Shelby County, this data tells you exactly where lane markings exist—helpful for anticipating construction zones or faded lines in poor weather. Small trucking businesses can verify route markings match state records before bidding on deliveries. It also clarifies which roads are state-maintained (like I-240) versus locally maintained when reporting missing or damaged markings.
How to read this data
ROUTE — The highway identifier (e.g., “I0240” for I-240).
FEAT_DESC — The marking type (e.g., “White 8” Solid Line, Single").
LOC_DESC — Where the marking is placed (e.g., “Right” for right-edge line).
DATE_COLL — When the marking was last surveyed (e.g., “1427155200000” = March 2016).
Try it yourself
Check if your regular commute route (like I-240 Exit 16B) has documented pavement markings by searching TDOT’s map viewer with the ROUTE and EXIT_ fields.
