|Route outline (key)|
The B6321 heads northeast from the Northumberland town of Corbridge.
The road starts on the B6318 to the east of Halton Shields and heads southwestwards along a road that to begin with is almost completely straight. The road descends and starts to become bendier on reaching Aydon. Although the road layout here may suggest otherwise, the B6321 has always bypassed the village centre.
A few hundred yards further on the road goes over the A69 Corbridge bypass before descending into the town along Aydon Road. The roads get narrower and soon a T-junction is met. The road is forced to TOTSO left here onto a one-way loop. The road continues along the tiny Princes Street to reach another T-junction; from here northbound traffic is diverted to the west. It travels along the B6529 for a short distance, having to TOTSO right to go round three sides of the churchyard to TOTSO left back onto the B6321.
Originally the B6321 ended at the T-junction at the southern end of Princes Street. The road ahead and to the right was the A68, whereas the road to the left was the A69, which now multiplexed along the A68 for a short distance. Now, however, both these roads bypass Corbridge. As such, the road to the right is the B6529 and left the B6530 but the B6321 continues ahead along the ex-A68. It quickly crosses a narrow bridge over the River Tyne, whose flow is controlled by traffic lights and which must have been a major bottleneck before the bypass was built.
On the far side of the river a roundabout is reached. The B6529 reappears and turns left, along the ex-A68, whereas the B6321 turns right along the original line of the A69. The road passes the cemetery and crosses a level crossing over the Tyne Valley Line. It ends shortly afterwards on the A695. That road has to TOTSO here as it now takes on the old A69 to Hexham.
