Mendip's motorists will have three road closures to avoid nearby on the National Highways network this week.

And one of them is expected to cause moderate delays – with drivers facing a wait of between 10 minutes and half an hour.

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

• A303, from 9pm August 11 to 6am August 13, moderate delays (10-30 minutes): A303 eastbound, Podimore Rbt - carriageway closure for barrier/fence safety repairs, diversion - A303 westbound to Ilchester, A37 southbound, A359 northbound, rejoining the A303 westbound, at Sparkford.

• A303, from 8pm August 19 to 6am August 20, slight delays (under 10 minutes): A303 both directions Sparkford to Podimore lane closures - for Sparkford to Ilchester improvement scheme.

• A303, from 8pm August 21 to 6am August 22, slight delays (under 10 minutes): A303 both directions Sparkford to Podimore lane closures - for Sparkford to Ilchester improvement scheme.

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