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 three closures are due to start this week:
• A3, from 8pm May 22 to 6am May 26, slight delays (under 10 minutes): A3 both directions Hindhead Tunnel, Contraflow for tunnel maintenance.
• A3, from 9pm May 30 to 6am May 31, moderate delays (10-30 minutes): A3 northbound, Hammer Lane, slip road and lane closures for resurfacing work.
• A3, from 8pm June 1 to 6am June 2, slight delays (under 10 minutes): A3 northbound, Upper Hammer Lane, slip road and lane closures for inspection work.
National Highways is responsible for maintaining motorways and major A-roads, so closures of smaller roads will not be included in their schedule.
