The Tennessee Department of Transportation announced traffic preparations for Bonnaroo 2026 in Manchester, saying it will staff special units and ban construction-related lane closures on Interstate 24 as more than 45,000 people arrive for the festival from June 11 through June 14.
TDOT said the no-lane-closure window runs from 6 a.m. on Wednesday, June 10, through 7 p.m. on Monday, June 15, and that its HELP and Rural Service Patrol units will assist with traffic management while the agency works alongside the Tennessee Highway Patrol, the Manchester Police Department, Manchester Fire and Rescue, the Coffee County Sheriff’s Department, the Coffee County Emergency Management Agency and festival promoters.
The scale is straightforward: Bonnaroo returns to its 700-acre Middle Tennessee farm — the site it has used since 2002 — and will bring a surge of vehicles on and off I-24 over a multi-day period. TDOT is offering several real-time options for drivers, including SmartWay traffic cameras, a 511 line for nonemergency travel information from cell phones and an 847 number that connects callers to the nearest Tennessee Highway Patrol dispatch office; life-threatening events should be reported to 911.
“TDOT continues to work closely with our partner agencies to support safe, reliable travel throughout the Bonnaroo Music and Arts Festival,” said Will Reid, and added that the agency’s “priority remains keeping traffic on I-24 flowing efficiently while ensuring festival attendees can enter and exit the site safely.” Reid said his team is confident it can maintain smooth travel conditions throughout the event weekend.
Manchester has seen increased traffic during Bonnaroos in the past, and state planners are framing the lane-closure ban as a way to keep maximum capacity on the interstate while incidents are cleared. The operational picture will rely on coordinated patrols and the roadside assistance units TDOT is deploying to remove disabled vehicles and respond to incidents more quickly than routine traffic would allow.
That coordination is the practical response to a clear tension: the festival is expected to draw a large crowd but TDOT has not published estimates of how many minutes of delay drivers should expect on I-24 during the peak arrivals and departures. Officials promise open lanes, extra staffing and real-time tools, but the department’s public guidance stops short of predicting specific travel times or quantifying peak congestion.
Drivers planning travel should assume heavier-than-normal conditions and use the resources TDOT is promoting. Dial 511 from a cell phone for traffic and construction dispatch, use the SmartWay cameras to check conditions before departure, and call 847 to reach the nearest Highway Patrol office if an incident requires THP coordination. For emergencies, dial 911. The HELP and Rural Service Patrol units will be positioned to clear incidents and assist motorists, which officials say should reduce secondary delays.
Bonnaroo 2026 runs Thursday through Sunday, with the no-construction-closure period bookending the event. The next operational milestone to watch is 7 p.m. on Monday, June 15, when the restriction on construction-related lane closures along I-24 near the festival expires; until then, TDOT’s traffic posture remains focused on keeping lanes open and staffing more on-road resources than usual.
If you are traveling to or through Manchester this weekend, the only verifiable certainty is the planning: expect increased traffic, follow real-time updates from TDOT and partner agencies, and allow extra time for travel — because specific delay estimates are not part of the department’s public plan. Watch SmartWay, call 511 before you go, and know the no-lane-closure period ends at 7 p.m. on Monday, June 15.
