Thousands of rock and heavy metal fans have started setting up their tents at Donington Park for Download Festival.
A crowd of more than 60,000 is expected to descend upon the arena during the three day rock concert, which starts tomorrow and runs through to Sunday. Aerosmith, Linkin Park and Avenged Sevenfold will be headlining the festival.
The line-up also features popular acts including Fall Out Boy, Rob Zombie, The Offspring and Bad Religion.
Meanwhile, the Highways Agency is urging festival-goers to plan their journey and allow plenty of time to get to the event.
Road users not heading to the festival are also being advised to seek alternative routes to avoid delays, and people travelling to East Midlands Airport, near the festival site, are being reminded to leave plenty of time for their journey.
Campers filtering into the grounds yesterday were already enjoying the festival atmosphere. "It's great here. It's the best Download Festival I've ever been to," said Peter Matuszewski, of Market Harborough.
"It's nice and sunny and everybody is so friendly."
He said he was looking forward to socialising around the campsites before watching favourite band Linkin Park take to the stage.
With traffic chaos in the area predicted, festival organiser Live Nation UK is encouraging as many people as possible to travel by bus, coach or train and have teamed up with liftshare.com to make sharing transport to Download easier.
Shuttle buses are also being put on to get people from Derby and Loughborough train stations.
A traffic plan is in place to keep traffic away from the village of Castle Donington.
Steve Parker, Highways Agency emergency planning manager for the East Midlands, said: "Major roads and motorways in the area, including the M1, A42, A50 and A453, are likely to be busy.
"All routes to the festival will be well signposted but people travelling in the area should plan their journey in advance and check the latest travel conditions before they set out.
"Festival-goers with iPhones will be able to check the traffic conditions using our Highways Agency travel news app or can follow us on Twitter @HAtraffic_emids, as long as it is safe to do so."
Donington Park is located next to East Midlands Airport, four miles west of junction 23a of the M1 and five miles from junction 24.
Anyone travelling to the airport should allow plenty of extra travel time for their journey.
The Highways Agency will be using electronic message boards on the surrounding motorways to advise people of any delays. Further information is available from the Highways Agency Information Line on 0300 123 5000. Noise levels will be controlled for those living in surrounding villages.
If any resident feels the noise has reached an unacceptable level, they can phone the event organisers anytime on 0845 0360470.
