What this tracks
This dataset records the locations and specifications of concrete barrier walls installed along Tennessee’s interstates, state routes, and major highways.
Why it matters to you
If you’re planning a road trip or daily commute in Tennessee, this data shows you where concrete barriers create lane restrictions or affect visibility on major routes. Construction companies bidding on highway projects can identify existing barrier locations to plan around. Emergency responders can use this information to understand access limitations when responding to highway incidents, since concrete barriers affect where vehicles can cross medians or exit roadways safely.
How to read this data
ROUTE — identifies the specific highway, like I0040 for Interstate 40. COUNTY_NAME — shows which Tennessee county contains each barrier section, such as Shelby County. FEAT_DESC — describes the barrier type, with samples showing “Jersery Barrier” (likely Jersey Barrier, a common concrete divider design). LOC_DESC — indicates whether barriers are on the “Right” side or other positions relative to traffic direction. HEIGHT — measures barrier height in feet, with the sample showing 2.9 feet. BEG_LOG and END_LOG — mark the start and end points along the route using mile markers, like 0.141 to 0.152 mile markers.
Try it yourself
Look up your regular highway route using the ROUTE field to see where concrete barriers might affect your drive. If you frequently travel Interstate 40 through Shelby County, you can find the exact mile markers where barriers are installed and plan lane changes accordingly before reaching those sections.
