North Somerset'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 delays 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:

• M5, from 9pm April 18 to 6am April 24, slight delays (under 10 minutes): M5 southbound, junction 19 to 20, lane closure for surveys.

And a further five closures will begin over the next two weeks:

• M5, from 9pm April 24 to 6am May 1, slight delays (under 10 minutes): M5 southbound, junction 18 to 20, lane closure for surveys.

• M5, from 9pm April 24 to 6am May 1, slight delays (under 10 minutes): M5 northbound, junction 20 to 19, lane closure for surveys.

• M5, from 8pm April 25 to 6am April 26, moderate delays (10-30 minutes): M5 northbound, junction 21 entry slip closed for carriageway repairs. Diversion via, junction 22 and back.

• M5, from 8pm May 1 to 6am May 3, slight delays (under 10 minutes): M5 both directions, junction 19 exit slips, lane closure for surveys.

• M5, from 10pm May 1 to 6am May 3, slight delays (under 10 minutes): M5 southbound, junction 18 to 19 lane closure for drainage works.

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