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 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:

• A36, from 11am March 15 to 6pm March 21, slight delays (under 10 minutes): A36 Shawford, traffic lights installed by Wales and West Utilities.

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

• A36, from 8pm March 20 to 6am March 21, moderate delays (10-30 minutes): A36 both directions Warminster Road roundabout to Beckington Services roundabout (A361) carriageway closures for resurfacing, northbound, diversion from Bath Road roundabout Warminster, A350, A363 Westbury Road, Southwick Road, Wynsome Street and A361. Reverse for southbound.

• A36, from 8pm March 21 to 6am March 22, slight delays (under 10 minutes): A36 Woolverton, multiway traffic lights for signs works.

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