Last checked Nov. 13, 2026. This page is refreshed every week. Sources: TDOT’s Region 3 lane closure report for Nov. 8-14 (PDF), the City of Clarksville’s news feed and TDOT’s project pages, checked Nov. 7; city notices rechecked Nov. 13. TDOT posted its report for Nov. 15-21 on Nov. 12, but the report file could not be opened on Nov. 13, so next week’s state route closures are not listed here yet. Check TDOT SmartWay before you travel.

Live conditions: TDOT SmartWay (or dial 511) for I-24 and state routes, and the city’s traffic cameras. The city says many of Clarksville’s major roads are state highways, so TDOT handles them; the city’s Street Department handles the rest.
