Wood, door frames, a bath tub and rubble were dumped on a Stoke-on-Trent road.
7.5 tonnes tonnes of waste was left on Redhills Road, in Milton, last night - causing disruption to traffic this morning.
The rubbish as now been moved by the city council, who are appealing for help to find those responsible.
Cllr Carl Edwards, cabinet member for environment, said: “It’s shocking and unacceptable that someone thinks it’s perfectly fine to dump rubbish wherever they want, with no thought for the consequences on the environment and the public.
“Cleaning up any fly-tipped waste is time-consuming and expensive – this particular incident required us to close a road in the morning rush-hour, and we had to divert teams from routine work to clear it up. Thankfully we quickly got everything done and back to normal.
“The cost of an incident like this is ultimately paid for by council taxpayers, money that could be spent in other ways that directly benefit residents. It is doubly annoying when you consider that the city council would have readily and lawfully taken the waste away by appointment for a very small charge.
“This level of fly-tipping would have needed a transit tipper or LGV van to carry out. I would encourage anyone who has information or saw anything suspicious in the area to get in touch with the council. If you were driving in the area yesterday evening, it might be that you have caught something on your dash cam which could be useful to our investigation.”
Anyone with information about who might have dumped the waste is encouraged to contact the council on 01782 234234 or email email@example.com.
