A large amount of builder's waste was alight in skips and industrial containers.
Marc Howson, watch commander at Wigan fire station, said: "There was quite thick smoke drifting across Wallgate so we got a lot of calls about it."
Crews from Wigan and Bolton fire stations spent around one-and-a-half hours tackling the blaze.
They managed to stop the flames spreading to nearby buildings.
It is thought the fire started as controlled burning, which was left unattended in a brazier.
Mr Howson added: "Make sure that if you do any controlled burning it's completely out before you leave it."
