If you have no plans to attend Bonnaroo but still must drive through the festival area in Coffee County from Thursday to Sunday, the Tennessee Department of Transportation suggests several detours to get around traffic snarls.
Like a return trip to the 1970s, the speed limit on 25 miles of Interstate 24 later this week will drop to 55 mph to improve safety for travelers during the Bonnaroo Music & Arts Festival in Manchester, Tenn.
It's all about safety, officials said. The temporary speed limit, now in its second year, affects I-24 from mile marker 104.6 to mile marker 129.4 and remains in effect until the festival is over Sunday night.
Tennessee's Highway Patrol and Department of Transportation are teaming up with the Coffee County Sheriff's Office and Manchester Police Department to keep traffic moving as the festival-faithful, numbering 80,000 or more, start piling into the county today.
Gates this year open at 8 p.m. CDT today to give people more time to get their vehicles into the campgrounds.
Coffee County Sheriff Steve Graves said Tuesday that traffic will start picking up this morning and grow heavier this evening and into Friday when many working travelers start to arrive.

"It really gets busy," Graves said. "Last year, our busy time was early morning on Thursday. We were lucky last year because it was a steady stream instead of everybody showing up at once."
The earlier opening on Wednesday is intended to spread and ease the flow of traffic.
"The priority is to make this year's festival safe and secure for travelers and festivalgoers," Tennessee Highway Patrol Col. Tracy Trott said in a news release. "State troopers will work to manage the increased traffic on Interstate 24 and provide aerial support to relay important information on the ground."
The state's bright green HELP trucks will be on standby, officials said. Other plans include moving inbound festival traffic to the right lane and/or the right shoulder.
"We won't have any significant lane closures on I-24 or any of the detour routes," TDOT spokeswoman Jennifer Flynn said Tuesday, noting that even small projects on the detour routes won't cause any problems.
Flynn said that since TDOT began dealing with Bonnaroo in 2002, officials have tweaked efforts to make travel smoother each year.
The sheriff said people should stay as informed as possible about traffic accidents or other unforeseen traffic stalls. Traffic around Manchester will get heavy around noon on Saturday and Sunday as festivalgoers arise and head into town for supplies, food or just to cool off for a while, he said.
The average wait in line to enter the festival is between two and three hours, Graves said, so "bring your patience."
