Farnborough International Airshow gets under way
Motorists are being warned to expect longer journey times as the international airshow gets under way in Farnborough, Hampshire.
The six-day event attracts around 250,000 visitors, many from the international aerospace industry.
The Highways Agency says some congestion is expected around the M3 J4-4a at Frimley, north of Farnborough.
Traffic is expected to be heaviest at the weekend when the show opens to the public.
