Park Bridge is an area of Ashton-under-Lyne, in the Metropolitan Borough of Tameside, in Greater Manchester, England.

Samuel Lees junior founded Park Bridge ironworks in 1786 on 14 perches of land rented from the Earl of Stamford.

Under Hannah Lees, the ironworks was expanded including the construction of a weir and a water power building on the River Medlock.

[2] The ironworks remained the largest such works in Tameside, including a nearby colliery and associated with the Oldham, Ashton and Guide Bridge Railway.

Because the buildings were not recorded before their demolition, the site of the ironworks is of interest to archaeologists – particularly the University of Manchester Archaeological Unit – as part of the development of the later iron industry in the north west.
