Drivers in and around St Helens will have three National Highways road closures to watch out for this week.

And two of them are expected to cause moderate delays – with motorists facing holdups of between 10 and 30 minutes.

The latest expected works list, with notes from National Highways, shows that one closure already in place is expected to carry on this week:

• A580, from 9pm August 5 to 6am August 12, moderate delays (10-30 minutes): M6 northbound and southbound, J21a to J26 - Lane closure for Construction improvement/Upgrade on behalf of Costain.

And a further two closures will begin over the next two weeks:

• M58, from 9pm August 12 to 6am August 18, moderate delays (10-30 minutes): M6 North and southbound, junction 21A - 26 lane closures and carriageway closures due to improvement works.

• M62, from 8pm August 13 to 5am August 14, slight delays (under 10 minutes): M62 eastbound, six to 7 - lane closure for carriageway - reconstruction/renewal on behalf of National Highways.

National Highways is responsible for maintaining motorways and major A-roads, so closures of smaller roads will not be included in their schedule.
