Dumfriesshire Clydesdale and Tweeddale MP David Mundell is calling for a special summit meeting to discuss the state of the A708 tourist route between Moffat and Selkirk.
The scenic route, whilst an important link to the Borders, is suffering from under investment, resulting in subsidence and serious potholing.
The road was closed for several days in April after a large section collapsed into a stream, forcing motorists to take lengthy detours.
Now local MP David Mundell wants action to bring the busy road up to an acceptable standard, and is calling on the Scottish Government to provide more support to the two affected local councils.
“I am now planning to call a summit at Moffat Water Hall with affected local residents, the police, Dumfries and Galloway Council, and local councillor Graeme Tait, in the hope that finally we can come up with proposals to improve this vital link,” said Mr Mundell.
The MP, who has previously warned of potential problems on this busy Borders tourist route, has already written to Scottish Transport Minister Keith Brown, urging him to provide support to Dumfries and Galloway Council.
Mr Mundell went on: “The A708 is a direct link route between Dumfries and Galloway and the Scottish Borders and I and others have expressed concerns in the past about the condition along stretches of the scenic route. Sections of the road have collapsed before with barriers put in place, effectively creating single-file traffic.
“April’s road closure was, sadly, something was inevitable and unless this road is upgraded I expected similar problems.
“It is now clear that repairs and upgrades are beyond the resources of the local councils and that is why I called on the Scottish government to get involved. This is an important A class road and one essential to tourism, transport and local people, therefore it is imperative it is repaired as soon as possible.
“Without investment there could be other incidents similar to April’s collapse. It is not enough just to have repaired that section - there must be a longer term upgrade of this route, and Scottish Borders and Dumfries and Galloway simply don’t have the resources to do this themselves without aid from the Scottish Government,” said Mr Mundell, adding "Local people have been calling for action for years and it is about time the Scottish Government acted responsibly and recognised the need to invest in this road before its terrible state of repair results in a serious incident."
