North Somerset's motorists will have five 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 five closures are due to start over the next two weeks:

• M5, from 8pm March 11 to 6am March 13, slight delays (under 10 minutes): M5 Both Directions, junction 21 to junction 22 lane closures for structural inspection.

• M5, from 9pm March 14 to 6am March 15, slight delays (under 10 minutes): M5 northbound, junction 19 to 18 lane closures for structure maintenance.

• M5, from 9pm March 15 to 6am March 16, slight delays (under 10 minutes): M5 northbound, junction 19 to 18 lane closures for structure maintenance.

• M5, from 8pm March 23 to 6am March 24, moderate delays (10-30 minutes): M5 northbound, junction 21 to 20 closed for carriageway repairs. Diversion via A370, A4 to M5, junction 18, (Clean Air Zone charge suspended on diversion route during closure times only).

• M5, from 8pm March 24 to 6am March 26, slight delays (under 10 minutes): M5 northbound, junction 21 entry slip road closed for carriageway repairs. Diversion via M5, junction 22 and back.

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