What this tracks
This dataset shows sections of Tennessee highways adopted by volunteer groups through the state’s Adopt-A-Highway program.
Why it matters to you
If you’re planning a roadside cleanup or looking to volunteer, this data tells you which stretches of highway already have dedicated groups maintaining them—so you can focus on unadopted areas. For businesses near highways, it shows which sections are regularly cleaned, which may influence property maintenance decisions or community partnership opportunities. Tennessee’s program has removed over 12 million pounds of litter since 1989.
How to read this data
NBR_RTE — The highway route number (e.g., “SR050” for State Route 50).
BEGIN_LOG_MILE and END_LOG_MILE — The mile markers where the adopted section starts and ends (e.g., 17.7 to 20.0 means the group maintains that 2.3-mile stretch).
COUNTY — The county where the adopted section is located (shown as a numeric code like “41”).
Try it yourself
Check if your regular commute route has an adopted section by searching TDOT’s Adopt-A-Highway map for the highway number (like SR050) and seeing if any groups maintain your stretch between the mile markers shown.
