They are the potholes so vast they've been described as "like canyons". Huge grooves of trench-like craters have blighted one of Manchester's busiest arterial routes as the Princess Parkway becomes Princess Road into the city.
The section of road, from Didsbury through Moss Side and Hulme, is one of the main routes into Manchester city centre and is used by thousands of motorists every day. But that has left parts of the dual carriageway road - on both north and south bounds sides - with vast troughs of pothole damage down the lanes.
The road has become so bad that even Happy Mondays star Bez complained about it in a recent interview with the MEN. And his description rather neatly sums up the situation.
