Canterbury City Council says it intends to deal with the mounds of rubbish which have appeared on a lay-by next to the A2 at Harbledown.
On Monday, the Canterbury Journal revealed that rubbish including urine-filled bottles had accumulated next the North Downs Way, a route for pilgrims entering the city.
Council leader Simon Cook is understood to have personally intervened to ask officers to investigate the situation at Faulkners Lane.
Council spokesman Leo Whitlock said: “Our enforcement officers have been sent to the area to investigate any flytipping while our contracts team is arranging for the public land to be litter picked as soon as possible.
“The responsibility for the disgusting state of the A2 rests with those who are too lazy to either take their rubbish home with them or dispose of it properly and instead decide to throw it out of the window.
“Their selfishness now means we have to make arrangements to litter pick the side of the road at the cost of tens of thousands of pounds to council taxpayers.”
Cleaner Canterbury campaigner Beverley Paton described the site by the A2 as “unbelievable” and a “reeking cesspit”.
The urine-filled bottles are usually left by drivers who use while on the road and then dispose of them when they stop.
Canterbury City Council is now preparing for a full clean of the area.
Mr Whitlock went on: “Our contractors are working with Highways England contractors to find suitable dates in order to minimise disruption to drivers because lanes need to be closed to protect workers.
“Costs are kept to a minimum if litter picks can take place during roadworks.
“Next week councillors will decide whether to increase fines for littering to £150 from £80.
“And they will discuss the introduction of a new fixed penalty notice for litter thrown from vehicles where its keeper is held responsible and where evidence from cameras will be allowed.
“The council is taking the issue of littering, flytipping, dog fouling and graffiti incredibly seriously.
“As well as taking enforcement action and fining or prosecuting offenders wherever we can, we launched our Love Where We Live campaign in February.
“This is designed to persuade people to look after what is a beautiful place to live, work in and visit if people don’t drop litter, let their dog foul without clearing it up, daub graffiti or flytip.”
Canterbury City Council has been trying to encourage people to look after the district with its “Love Where We Live Campaign”.
It is also working on ways to reduce the use of plastic bottles which make up much of the litter found on streets and other open areas.
