Reading's motorists will have four road closures to avoid nearby on the National Highways network this week.

And one of them is expected to cause moderate delays – with drivers facing a wait 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:

• M4, from 8pm January 21 to 6am February 8, slight delays (under 10 minutes): M4 eastbound, junction 12 to 10, Lane closure for Smart Motorways.

• M4, from 8pm February 4 to 6am February 5, slight delays (under 10 minutes): M4 westbound, junction 10 to 12, Lane closure for Smart Motorways.

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