North Somerset's motorists will have six road closures to avoid nearby on the National Highways network this week.

And two of them are expected to cause moderate delays – with drivers facing holdups of between 10 and 30 minutes.

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

• M5, from 8pm October 17 to 5am October 18, slight delays (under 10 minutes): M5 southbound, junction 21 to 22 lane closure for vegetation works.

• M5, from 10pm October 17 to 6am November 7, slight delays (under 10 minutes): M5 northbound, junction 19 to 18 - Lane closures for Structure maintenance.

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

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