ReportWhat the SmartWay feed carried over the holiday weekend.
I-40 crosses the whole state, Memphis through Nashville and Knoxville to the North Carolina line, about 455 miles. I-24 cuts diagonally through Nashville and Chattanooga. I-65 runs south to north through Nashville, and I-75 links Chattanooga and Knoxville on its way to Kentucky. I-81 peels off toward Virginia in the Tri-Cities corner of East Tennessee.
The fog banks where I-40 threads the gorge at the North Carolina line are notorious. Visibility can collapse with almost no warning, and pile-ups there have closed the interstate for hours. Winter ice on the Cumberland Plateau grades and spring thunderstorms across Middle Tennessee round out the driving weather. TDOT gives incident and rolling-roadblock locations by mile marker on SmartWay.
In October 2026, MileCheck's archive of the SmartWay feed held 280 unique reports, including 28 closure reports, 26 crash reports, 203 work-zone reports and 2 weather reports. The routes with the most reports were I-24, I-40 and US-31. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the October Highway Report.
The map above shows full closures from the SmartWay feed as red markers, crashes in orange, and weather and hazard alerts in blue and purple. Closures the DOT has posted for a future date are listed as scheduled, and ramp and lane closures sit under the toggle so the list stays readable. The page checks MileCheck's feed every five minutes. If the feed cannot be reached the page says so instead of showing an empty map. For the official list, open SmartWay.
SmartWay is the official source, and dialing 511 in most states reaches the same information by phone. This page reads the same SmartWay feed and adds the Tennessee cameras, the corridor and pass pages, and your own mile marker if you carry the app.
This page checks MileCheck's feed every five minutes. SmartWay updates individual reports on its own schedule. Source update times are shown when available.
