This junction is the only one where the A74(M) meets a road that doesn't start with a seven, in this case the B6357. It also means that going south you are almost at England.
The split-diamond layout, completed in December 1992, is essentially a clone, slightly displaced sideways, of the previous junction on the dualled A74, opened in 1969. It sees the south facing slips meet the B7076, which passes under the motorway at a significant skew, pushing the two sliproads apart by some distance. Both approach the B7076 from the west. The north facing slips meet the B6357 several hundred metres to the north, which crosses over the motorway at right angles. The two b-roads then meet at the edge of the village of Kirkpatrick Fleming, with a mini roundabout located directly above the railway line on a wide bridge. The bridge which carried the then A74 over the railway still exists, just west of the corresponding bridge on the motorway.
