Drivers are being warned to be prepared for traffic delays when the V Festival comes to Chelmsford this weekend.
More than 70,000 people are expected to the attend the event at Hylands Park from Friday to Sunday.
Nigel Allsopp, the Highways Agency's events planning manager for the East of England, said: “Although there won’t be any road closures, we expect the A12 near Chelmsford, the M11 junctions 7 to 9 and M25 junctions 29 to 28 to be much busier than normal.
“The campsite opens at midday on Friday and closes at midday on Monday, so we expect the run-up to and from these times to be particularly busy. We also expect traffic to be busier in the area throughout the weekend.
“We strongly advise festival goers and road users in the area to plan ahead and ensure that vehicles have sufficient fuel, and that they have plenty of drinks, such as water, available in the vehicle in case of any delays.”
Traffic is also expected to be busy in the same areas on Monday morning as people head home from the festival.
