Motorists could experience delays of up to 30 minutes due to one of many road closures affecting the major roads in, out and through Swindon this week. 

Drivers in the town will have nine National Highways road closures to watch out for over the next seven days.

Six of the nine closures listed are already in place and are just carrying on into this week and beyond.

While most shouldn't cause any significant disruption, two of them are also expected to cause "moderate" delays – with motorists facing holdups of between 10 minutes and half an hour.

The fill list is as follows: 

• M4, from 8pm March 28 to 6am April 29, slight delays (under 10 minutes): M4, junction 15 eastbound, exit Slip, Lane one closure for M4, junction 15 improvement works.

And a further three closures will begin over the next seven days:

• M4, from 8pm April 19 to 6am April 21, moderate delays (10-30 minutes): M4, junction 15 eastbound, exit Slip, Full slip road closure for M4, junction 15 improvement works.
