The A57 is a major road in England. It runs east from Liverpool to Lincoln, via Warrington, Cadishead, Irlam, Patricroft, Eccles, Salford and Manchester, then through the Pennines over the Snake Pass (between the high moorlands of Bleaklow and Kinder Scout), around the Ladybower Reservoir, through Sheffield and past Worksop. Within Manchester a short stretch becomes the A57(M) motorway (the Mancunian Way).

The 3-mile (4.8 km) £4 million Aston relief road in Sheffield opened in mid-1985, with the old route now designated as the B6200.
