FLY-TIPPERS dumped a van-load of building waste in a country lane.
A pile of insulating foam and chunks of plasterboard was strewn across the middle of Braziers Lane in Ipsden.
It was mixed with wooden beams and sheets of plastic and was blocking access for walkers, cyclists, horse riders and motorists.
A driver later swept it to the side of the single-track route so that people could get through.
Ipsden Parish Council reported the incident to South Oxfordshire District Council, which is responsible for tackling fly-tipping, and it sent out its contractor Biffa to clear the mess.
Councillor John Jeffery, vice-chairman of the parish council, said: “We’re all amazed at how horrible people can be but this sort of thing is, thankfully, quite rare.
“You get the odd mattress dumped here once a year but it’s not a regular occurrence.
“Apart from good communication between the councils, which we always try hard to ensure, the most important thing is that residents report incidents to their parish and district councils.”
A district council spokesman said some evidence had been found that might help trace the culprits.
