Projects set to benefit from the significant investment include Stranraer Marina, 7 Stanes mountain bike trails and Gretna Star of Caledonia.
South West Scotland features in one of the five strategic ‘growth corridors’ of the Deal, with the Road Investment Strategy to be delivered by Transport Scotland, including improvements to the A75.
The Scottish allocation from the Deal is £85 million from the Scottish Government and £65 million from the UK Government in partnership with five local authorities including Dumfries & Galloway Council.
Ms Harper commented: “The Borderlands Inclusive Growth Deal is a game changer for our region and I welcome the fact this has now officially been signed showing the commitment made by the Scottish Government in partnership with the UK Government and five councils which will see our region’s projects develop.
“Up to £16m will be available from this Deal to transform Stranraer Marina and £4m will be invested to improve and extend the 7Stanes network of mountain bike trails across the region as well as investment into the Star of Caledonia at Gretna.
“News of 5,500 jobs is particularly welcome, especially following the devastating impact of Covid on my constituents who will be glad to hear of this significant investment into the area which will help boost the region’s economy by £1.1billion.”
