Drivers travelling on the M4 through Wiltshire over the Coronation Bank Holiday are advised to plan their journeys ahead of the Badminton Horse Trials.

The equestrian event starts on Thursday, May 4, and runs until Bank Holiday Monday, May 8.

It attracts the eventers to the Duke of Beaufort’s Badminton House grounds in South Gloucestershire, and with it, some 170,000 visitors over the five days.

This year’s event has a changed schedule on account of the coronation of King Charles III on Saturday, May 6.

With junction 18 of the M4 and the A46 near Tormarton likely to see higher traffic volumes, National Highways is reminding people making their way to the event and motorists travelling around the location to plan ahead.

Kathryn Wiltshire, South West Network Planner for National Highways, said: “Given the Bank Holiday weekend, the network is likely to see higher traffic volumes and the Badminton event will also see increased traffic around M4 junction 18 and the A46 to the south of the junction.

“Our aim is to keep the National Highways network running while keeping all road users safe and informed, and we’re advising all drivers to check our traffic and travel information channels, to plan ahead and allow plenty of time for their journeys.”
