Drivers in and around Wiltshire will need to keep their wits about them as 32 National Highways roads are expected to close over the next two weeks.

The M4 is set to experience the most roadworks out of National Highways' Wiltshire roads in the coming weeks, which will mean delays for hundreds of drivers who use the motorway to commute each day.

Of the 32 closures, three of them are expected to cause 'moderate delays' with holdups of up to half an hour.

Here are all the roadworks you will need to look out for in Wiltshire this fortnight.
