Anyone travelling to Devon County Show this week is being advised to plan their journey. There are thought to be around 100,000 people attending over the three days with increased traffic on the M5 north and south of junctions 29 and 30, the A30 east and west of Exeter and the A38 south of Exeter. The show begins tomorrow (Thursday) until Sunday at the Westpoint Showground near Exeter. Traffic is likely to be heavier on the Saturday this year, with Exeter Chiefs hosting Wasps in an Aviva Premiership play-off semi-final at Sandy Park. Gareth Price, Highways England emergency planning officer for the South West, said: Our aim is to keep the Highways England network running whilst keeping road users safe and informed. Exeter Chiefs have published their own information to direct supporters on the Saturday, and we advise all road users to check our traffic and travel information channels, set off early and allow plenty of time. Highways England provides live traffic information via its website at www.highways.gov.uk/traffic or from a phone or mobile device at m.highways.gov.uk. Travel information is also available by phone from the Highways England Customer Contact Centre on 0300 123 5000.
