Drivers in and around the Forest of Dean will have nine National Highways road closures to watch out for this week.

And one of them is expected to cause moderate delays – with motorists facing a holdup of between 10 minutes and half an hour.

The latest expected works list, with notes from National Highways, shows that seven closures already in place are expected to carry on this week:

• A40, from 7am January 4 to 5pm February 22, slight delays (under 10 minutes): A40 Lea to Huntley 24/7 traffic lights for apparatus installation (Gigaclear).

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

• A40, from 6am February 24 to 6am March 12, slight delays (under 10 minutes): A40 Dursley Cross temporary two-way traffic lights for emergency landslide works.

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