The Forest of Dean's motorists will have six road closures to avoid nearby on the National Highways network this week.

And one of them is expected to cause major delays – with drivers facing a holdup of at least 30 minutes. Another two will cause moderate delays of between 10 minutes and half an hour.

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

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