You may want to keep an eye out for what’s going on out on the road before planning your journey if you are driving in Wiltshire this week.

New information has shown that motorists will have 29 road closures to avoid nearby on the National Highways network over the coming days.

And one of them is expected to cause severe delays – with drivers facing a holdup of at least 30 minutes. Another two will cause moderate delays of between 10 minutes and half an hour.
