The grounds are ready just in time for Bonnaroo campers to start arriving Wednesday night.
The music festival is in its 12th year and over 80,000 people are expected to intend.
"I can't believe how big it's gotten. And it gets better every year. I think the people work well together every year. It's just a wonderful thing," said Lonnie Norman, the mayor of Manchester.
This year's headliners include Sir Paul McCartney, Mumford and Sons and Tom Petty and the Heartbreakers.
"It's music, art and community coming together for an amazing experience, people making friends and just having a good time out here in Middle Tennessee," said Rick Farman, Bonnaroo co-founder.
Gates to the General Admission Campgrounds for Bonnaroo open at 8 p.m. Wednesday in Manchester.
The VIP Campground opens at 7 a.m. Thursday.
"It's great. Hopefully we can keep everyone safe in our community and in the Bonnaroo community. And that's our goal every year. There's always an incident or two that's unpleasant. But at the same time, it's run well and it's a good thing," Manchester Police Chief Mark Yother remarked.
Traffic is expected to be heavy starting Wednesday night and throughout the weekend for the 12th annual festival.
For concert-goers who don't wish the drive, the Nashville Convention and Visitors Bureau partnered with festival organizers to offer a shuttle service from downtown Nashville.
The shuttle takes off from LP Field.
Weekend and single-day tickets and shuttle packages are still available.
Security is expected to be tighter this year in wake of the Boston Marathon bombings.
