Roads will be busier than usual this weekend when The Battle of Britain Anniversary Air Show is held at IWM Duxford.

Nigel Allsopp, Highways England events planning manager for the East of England, said: “Although there won’t be any road closures, we expect the M11 at junction 10 to be much busier than normal throughout the weekend.

“The Battle of Britain Anniversary Air Show has attracted a large number of visitors to IWM Duxford and we strongly advise road users in the area to plan ahead and allow extra journey time in case of any delays.

“The air show is advance tickets only and sold out, so if you don’t have a ticket please do not travel the air show.

“Drivers should check conditions before setting out and not travel to the air show unless they have a ticket.”

Highways England is reminding road users about the event at the historic airfield and museum of aviation history on Saturday 19 and Sunday 20 September.

Anyone without a ticket should not attempt to travel to the event, as they will not be able to gain entry to the air show.

Highways England is working in partnership with the IWM Duxford and local authorities to help get traffic to and from the event efficiently and safely and to keep traffic flowing.

Anyone travelling through the area is advised to allow extra time for their journey, or to plan an alternative route or time.

Drivers are being advised to follow the AA signs rather than their own sat nav.
