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 severe delays – with motorists facing a wait of at least 30 minutes.

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