Drivers in and around North Somerset will have five National Highways road closures to watch out for this week.

And three of them are expected to cause moderate delays – with motorists facing waits of between 10 minutes and half an hour.

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 10pm March 19 to 6am March 22, moderate delays (10-30 minutes): M5 southbound, junction 19 exit slip road - carriageway closure for drainage works, diversion via M5, exit at, junction 20, turn and return to junction 19.

• 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).
