Drivers planning to use the M5 near Exeter are advised to plan their journeys ahead of this year's Devon County Show at the Westpoint Arena.

Congestion is predicted to be busiest in the morning as people arrive to the show, particularly the M5 northbound between junctions 31 and 30. 

M5 traffic will be directed to use junction 30 to access the showground via the A376 and A3052, while A30 westbound traffic will be directed to exit at the Daisy Mount junction and use the B3180 and A3052.

Drivers can get travel information on local radio and the @HighwaysSWEST Twitter feed, by phoning the National Highways Information Line on 0300 123 5000 or via the Traffic England website.

The show, to be held on Thursday May 16, Friday May 17 and Saturday May 18 averages an attendance of up to 100,000 people over the three days at Clyst St Mary,  with increased traffic anticipated on the M5 north and south of junctions 29 and 30, the A30 east and west of Exeter and the A38 south of Exeter.

John Ingram, South West network planner for National Highways, said: “We’re working closely with our partners at Devon County Council and Devon and Cornwall Police to give drivers as much advice as possible to help them plan their journeys during this busy period, and our traffic officers will be patrolling the M5, A38 and A30 to assist with any breakdowns and incidents.

“Junction 30 of the M5 could be particularly busy and the north approach to junction 30 could also see significant increases in traffic between 8am and 10.30am over the three days when visitors to the Devon Show could be using the motorway at the same time as commuter and freight traffic.

“The A30 east and west of Exeter and A38 south of Exeter could also see an increase and drivers are advised to plan their travel routes well in advance, and to keep up to date with the latest road conditions. Yellow signs will advise show visitors which route to take on the approaches to the show.”
