|Route outline (key)|
The B6357 is one of Britain's longer B-roads, running for just under 50 miles across southeast Scotland.
It starts at a roundabout on the B721 (pre-bypass A75) on the eastern edge of Annan (the original road started slightly further west and headed northeast along Stapleton Road past the hospital) and then heads north out of town. A turn to the right provides access to the A75 bypass, after which the B6357 crosses the latter road by means of a bridge; essentially this is a very simple GSJ. The road then continues in a more easterly than northerly direction across more-or-less flat land. Presently it bends sharply left to cross the Kirtle Water and reach Kirkpatrick Fleming. Here we cross the B7076 at a mini-roundabout situated above the West Coast Main Line. Just afterwards the north-facing slip roads to the A74(M) at J21 are met (for the south-facing slip roads we should have turned south along the B7076).
The B6357 continues northeastwards across undulating countryside. It goes through no places of any size but passes several buildings and the occasional hamlet. After running through Evertown the road TOTSOs right; ahead is the B720. A mile or so further on the road crosses the A7 at a staggered crossroads before descending into Canonbie and the valley of the River Esk. We reaches a T-junction and TOTSO left; this is actually the pre-bypass route of the A7, now numbered B7201 to the right. The B6357 goes through the village and crosses the river at a narrow bridge controlled by traffic lights. The first road to the left is the original line of the A7, now signed as a no-through-road.
The B6357 continues east into hillier terrain than before. It is soon crossed by the B6318 – one of the few Class II roads longer than the B6357. For the next few miles the road runs very close to the English border. It skirts the hills to the left, with the valley on the right containing the boundary. The road then starts to descend into the valley (by which time the border moves away to the east) and the countryside opens out. This is Liddesdale and the road follows the valley upstream for a considerable distance.
The next village is Newcastleton and the road goes along the main street. A mile or so further on the road crosses a narrow bridge over the Hermitage Water and bends round to the left to become the B6399; the B6357 TOTSOs right. It crosses the Liddel Water and continues up the increasingly narrow valley, crossing the stream again a couple of miles upstream.
At the hamlet of Saughtree we leave the Liddel Water and head off up the valley of a tributary, the Dawston Burn. This valley is narrow and soon peters out and, after a short section of open moorland, the road enters a forest, although there are several clearings to vary the journey. The summit of the route is met here, after which the road narrows and finds a valley to descend to reach a T-junction on the A6088 a few miles further on.
There is then a multiplex north for about a mile around the edge of Bonchester Hill and over the Rule Water at Bonchester Bridge. To the north of the village of that name the B6357 regains its number by turning right. It then continues along the valley, soon crossing the stream again. The road then heads off to the east to climb out of the valley before a few more miles of rolling hills lead to a descent into the valley of the Jed Water. The B6357 ends at a T-junction on the A68 on the near side of the stream just over a mile to the south of Jedburgh.
