ReportWhat the 511SC feed carried over the holiday weekend.
I-95 crosses roughly 200 miles of pine flats where every mile looks like the last. I-26 drops from the mountains near the North Carolina line through Spartanburg and Columbia to Charleston and the coast. I-85 carries the Upstate, Greenville and Spartanburg, between Charlotte and Atlanta. I-20 links Columbia west toward Augusta and Atlanta.
When a major hurricane threatens Charleston, South Carolina can reverse the eastbound lanes of I-26 so every lane flows inland toward Columbia. The reversal points, crossovers and re-entry instructions are all announced by mile marker. Winter ice is rare but shuts the Upstate when it comes, and 511SC posts closures and incidents by route.
In October 2026, MileCheck's archive of the 511SC feed held 24 unique reports, including 7 crash reports and 11 work-zone reports. The routes with the most reports were I-26, I-95 and I-77. 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 511SC 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 511SC.
