The Highways Agency is advising music lovers heading to the Download Festival this weekend to plan allow plenty of time to get there.
It is also warning drivers not heading to the festival at Donington Park to seek alternative routes or be prepared for delays.
More than 90,000 people are expected to attend the three-day festival, being staged from Friday, June 14, to Sunday, June 16, and surrounding roads are likely to be very busy.
Gates to the campsite were opened yesterday to allow an expected 70,000 campers to spread their arrival times.
Another 20,000 visitors are expected to buy daily tickets.
Campers planning to arrive today are also advised the A453 will be closed overnight in both directions between the M1 junction 24 and Parkway Station as part of the ongoing widening improvement.
It will be closed between New Road, Barton in Fabis, and the Crusader Island, at Clifton, from 8pm to 5.30am each night.
Traffic will be diverted via the M1 and A52 and the diversion route will be clearly signposted. Non-motorway traffic and local traffic routes will also be signed.
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."
Festival goers with iPhones will be able to check the traffic conditions the Highways Agency travel news app or can follow it on Twitter at the address below.
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 extra time for their journey.
The Highways Agency will be using their electronic massage boards on the surrounding motorways to advise people of any delays.
Extra Highways Agency Traffic Officers are also being deployed for the duration of the event around junction 24 of the M1 to assist motorists, clear incidents quickly and keep traffic moving.
