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

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

The latest expected works list, with notes from National Highways, shows that four closures are due to start over the next two weeks:

• A580, from 9pm July 29 to 6am August 5, 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 5 to 6am September 28, slight delays (under 10 minutes): M62 eastbound and westbound, junction 7 to 8 - lane closure for carriageway - reconstruction/renewal on behalf of National Highways.

• 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.

• M58, from 9pm August 12 to 6am August 17, moderate delays (10-30 minutes): M6 North and southbound, junction 21A - 26 lane closures and carriageway closures due to improvement works.

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