Just 7 miles long and running roughly north-south, the A707 is a link between Tweeddale (usually taken to be the upper reaches of the river) and Selkirk, and can also be used as part of an alternative to the A7 through Galashiels. It is wholly in the historical county of Selkirkshire.
Clovenfords - Selkirk
At its northern end the A707 starts at a roundabout on the A72 a mile south west of the village of Clovenfords, and follows closely the north bank of the River Tweed for several miles. At Caddonfoot, about a mile from the start, there is a sharp right-hand bend where the B710 turns left, cutting back to the centre of Clovenfords, then there is a particularly attractive stretch along the river in its narrow valley between wooded hills.
The A707 crosses the River Yair
At Fairnilee the B7060 continues along the north bank of the Tweed to join the A7 between Galashiels and Selkirk, but we take a sharp right over a light-controlled bridge across the river, then a sharp left to follow the south bank for a mile or so. The A707 then bears right to cross a shoulder of high ground before falling to the valley of the Ettrick Water on the outskirts of Selkirk. After passing the out-of-town Bannerfield housing scheme we TOTSO to the left, our line beside the west bank of the Ettrick being continued by the A708 as it starts here for Moffat.
Shortly after the TOTSO there is a junction on the right with a corner-cutting spur of the A708, then we cross the Ettrick and make a long sweeping climb to the centre of Selkirk on its high ridge. On the way the B7014 heads off to the left, avoiding the town centre to join the A7 to the north, then the B7009 joins us from the right from Ettrickbridge and after a short multiplex leaves to the left to join the B7014. After a final climb the A707 ends in Selkirk Square where the A7 has one of several sharp bends through the town, from this point going left for Galashiels and straight on for Hawick.
