A75

The A75 is a primary trunk road in Scotland that runs from Gretna to Stranraer, connecting the A74(M) motorway to the ferry ports at Cairnryan. The road is mostly single-carriageway, with some dual carriageway sections, and has been re-aligned and bypassed numerous towns and settlements due to its heavy freight traffic. Despite plans for upgrade, the road remains unfit for its current traffic volumes, with heavy goods vehicles making up to 90% of traffic. The road forms part of the international E-road, European route E18, and has been the subject of transport studies, including a 2020 study that outlined options for investment.learn more on wikipedia
