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

The latest expected works list, with notes from National Highways, shows that six closures are due to start over the next two weeks:

• M5, from 10pm September 3 to 6am September 4, slight delays (under 10 minutes): M5 southbound, junction 20 exit slip road - carriageway closure for horticultural works, diversion via M5, exit and turn at, junction 21 to return to junction 20.
