A huge operation to clear litter from a 26-mile stretch of the A41 started last month.
Work by Dacorum Borough Council (DBC) started on Monday, February 6 to clear rubbish from the central reservation from the road which runs between Kings Langley and Chipperfield.
A further two week operation to clear the slip roads, junctions and grass verges began on Monday, February 20.
More than 10.5 tonnes of litter and bulky rubbish was collected in the last clear up which cost an estimated £40,000.
The clear up of the litter pick is costly as it involves applying and paying for a traffic management system so that parts of the road can be closed as they are cleared.
Craig Thorpe, group manager for environmental services, said: “This is a huge task involving a team of up to 12 members of staff.
“It will cost us £25,000 in traffic management, labour, equipment and disposal costs to pick up litter which should not be thrown out of a car on a high-speed road.”
