“Archaeological mitigation” will begin from mid-November, with temporary cabins being moved into the area in this time in preparation for construction to begin, the agency said.

Once finished, the A57 Link Roads project will create two new link roads.
The first is the Mottram Moor Link Road – a new dual carriageway from the M67 junction 4 roundabout to a new junction on the A57(T) at Mottram Moor.
The other is the A57 Link Road – a new single carriageway link from the A57(T) at Mottram Moor to a new junction on the A57 in Woolley Bridge.
Work is expected to take three years to complete, according to the Department for Transport.
The project has divided opinion in the area, with the Campaign to Protect Rural England (CPRE) saying the new road could “harm public enjoyment” of the landscape.
But Luke Williams, transport manager at haulage firm Newell and Wright, said he was “over the moon” to hear that construction would begin this month.
In her speech, Chancellor Rachel Reeves also announced new rail investments for Greater Manchester, with electrified trains set to run from Manchester Victoria to Stalybridge this year, and between Wigan and Bolton in the future.
