Mountains of rubbish including fridges, building rubble and even cars has been dumped under the Denham Roundabout on the A40.

getwestlondonfirst reported the fly-tipping under the bridge on February 20. Since then the mass has swelled to around 600 tonnes, according to Highways England.

The rubbish has filled what was locally known as the ' Uxbridge Galleries' - an area taken over by graffiti artists who covered the pillars and walls of the flyover with their designs.

Highways England, which owns the land, has finally taken steps to clear the dumping site which lies just 100 metres from the Grand Union Canal and posed a significant fire hazard.

A Highways England spokesperson said: "We estimate that there is between 500 and 600 tonnes of litter at the site – 100 trucks worth of waste. We are working hard to clear this litter as quickly as possible, and have installed concrete blocks to restrict further access to the site.”

The site under the major arterial road is close to the Colne Valley Regional Park and locals have expressed concerns about the possible damage the tipping has caused.

Speaking in February, local resident Maggie Ditchburn said: "The amount of rubbish being tipped is becoming hazardous, polluting the waterway and the possibility of a fire could cause damage to the fly-over and traffic chaos."

At that time the site was strewn with some fridges and old furniture. Since then people have dumped hundreds of tons of building and household waste at the site.

Buckinghamshire County Council's (BCC) fly-tipping officers have been examining the site and have launched 30 active investigations to identify those responsible for the industrial-scale fly-tipping.

It is thought that illegal waste dumping has been carried out by unlicensed 'men in vans' accessing the tip through this open gate

There was initially confusion as to who owns the land, leading to a stale mate as it was not immediately clear if Hillingdon Borough or BCC was responsible for the site.

A spokesman for BCC confirmed the tip was on their side of the border and thanked concerned members of the public for alerting the council as well as warning householders about tipping waste.

"Householders who pay 'men in vans' to take their rubbish must check their waste removal licence" he said.

"Those homeowners who don't, could be liable for not acting with duty of care."
