A KEY route in and out of Saddleworth could be closed for up to six months, highway bosses have warned.
And a lengthy diversion route will be in place during the Ackers Farm Retaining Wall re-construction scheme on the A670 Standedge Road at its junction with the A62.
However, engineers say work will be suspended during “special” Saddleworth events such as Whit Friday, Yanks Weekend (August 11-12) and the Rushcart Festival (August 25).
There is no official start date for the job which is still at the tender assessment stage but it is unlikely to be within the next six weeks.
The work will then take between four to six months.
During the closure, traffic, particularly HGV transport, will be diverted along the A62 to Platting Road and Doctor Lane at Scouthead.
At the Platting Road junction with Stockport Road (A669), vehicles will be directed towards Greenfield and into Uppermill.
Access to Diggle, at both ends of the village, will be unaffected.
Engineers acknowledge drivers with local information can find shorter journey times.
