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:
• A3, from 8pm September 4 to 6am September 16, moderate delays (10-30 minutes): A3 both directions Longmoor to Hazel Grove, carriageway closures for tunnel maintenance.
And a further two closures will begin over the next two weeks:
• A3, from 9pm September 18 to 6am September 20, slight delays (under 10 minutes): A3 both directions Hindhead Tunnel, Contraflow for electrical work.
• A3, from 9pm September 21 to 6am October 7, slight delays (under 10 minutes): A3 both directions Hindhead Tunnel, Contraflow for maintenance works.
National Highways is responsible for maintaining motorways and major A-roads, so closures of smaller roads will not be included in their schedule.
