Thousands of historical artefacts have been discovered during the construction of the new bypass at Dunragit.
Everything from food vessels and urns, to jet necklaces and thousands of Mesolithic flints have been found. They have now been unveiled by Transport Minister Keith Brown.
The treasure trove was unveiled to mark the early opening of the new £17 million road.
One of the most exciting finds was a seasonal hunting camp, the earliest known Mesolithic dwellings in south west Scotland, dating back to the end of the last ice age.
The upgrade of the A75 has been going on for some time. The majority of the road is already open and has allowed lorries to bypass the notorious Challoch bridge.
Becuase of its height, it is is usually hit around eight times a year, causing traffic chaos on the road and the overhead railway.
Now parts of the route are dual carriageway motorists should find the stretch much easier to drive.
The artefacts haven't yet been evaluated, but once they are a decision will be made on when and where they will be put on public display.
With so much interest in them in the south of Scotland it is hoped they could exhibited where they were found.
