What this tracks
This dataset records the location and specifications of guardrails and cable barriers installed along Tennessee’s interstates, state routes, and other major highways.
Why it matters to you
If you’re planning a road trip or daily commute in Tennessee, this data shows which highway segments have safety barriers that could affect visibility, emergency stopping areas, or roadside access. Construction companies and landscaping businesses can use this information to identify where guardrails might limit equipment access or require special permits for roadside work. The data also helps you understand why certain highway sections feel safer or more enclosed than others.
How to read this data
COUNTY_NAME — the Tennessee county where each guardrail segment is located, like Lawrence or Davidson. ROUTE — the specific highway number where the barrier is installed, such as route 05694. FEAT_DESC — the type of barrier system, with values like “W-Beam” for standard metal guardrails or cable rail systems. LOC_DESC — which side of the road the barrier protects, showing values like “Right” for the right shoulder or median areas. BEG_LOG and END_LOG — the precise mile markers where each guardrail section starts and ends, such as from mile 1.417 to 1.432.
Try it yourself
Look up your regular highway route by searching for the route number in the ROUTE field, then check the COUNTY_NAME to find guardrail locations in your area. You can see exactly which mile markers have barriers and whether they’re on the right or left side of the road, helping you identify the safest areas to pull over in an emergency.
