The area along Abberley Street and Dugdale Street in Smethwick has been lined with mountains of waste, dumped by fly-tippers.
The two roads are part of an industrial zone near the Cape Hill area of the town, just on the border with Birmingham, next to Rotton Park and the new Midland Metropolitan Hospital, which is currently in development.
The rubbish runs along Abberley Street to the corner of Dugdale Street and is about 20 metres long and several metres deep from the path to the fence along the B.G. Plating car park.
It has been accumulating around the area for more than a month, with fly-tippers regularly seen dumping bags of rubbish and some of which has attracted rodents and other wildlife.
Among the rubbish being left at the scene includes old mattresses, beds and lounge furniture, as well as a mound of clothes and other used fabrics.
Additionally, children's toys can be seen, as well as a range of household items such as water containers, hot water bottles and kitchenware.
The largest amount of the rubbish, and the cause of some of the wildlife, has been the bags of rubbish, including food and drink waste.
The rubbish has proved an unpleasant site for local residents and workers and is casting a shadow over the development of the £900 million super-hospital.
A spokesman for Birmingham City Council said: "There’s never an excuse for littering or fly-tipping our streets, regardless of if it is private or council-owned land.
"It shows no respect to our city or the people who live and work here.
"We all have a personal responsibility to safely dispose of our own waste.
"We have enforcement staff that can and do issue fixed penalty notices, with court action pursued where this is appropriate.
"As well as harming our shared environment, dealing with waste related issues like this places a strain on our resources and ultimately costs the people of Birmingham money, which could be better spent on other essential services.
"But in order to prosecute, we need evidence and eyewitness accounts, so would urge anyone with any information on any case to get in touch with us as soon as possible after."
