The B4061 is a loop off the A38 to serve the town of Thornbury.
It starts at traffic lights at Alveston and heads north out of the village, quickly meeting the B4461. It then descends to Thornbury and goes through the town. It runs along the High Street before bending sharply right into The Plain, after which it turns left at a mini-roundabout.
After leaving town the road heads eastwards through Upper Morton and presently arrives at the A38 again at Whitfield, where the road ends. Shortly before this junction a spur heads southwards to provide access to the southbound A38, although there is no restriction of movement at the northern junction.
Originally the A38 went through Thornbury and the B4061 bypassed it to the east. However, the southern end of the B4061 was further north and the northern end further west (the street names Old Gloucester Road show the original route of the B4061). It was soon decided that it would be better to have the main road bypass the town and so the B4061 and A38 swapped numbers in this area in the late 1920s. Later still, the corner was cut off in Alveston (the old road there is now unclassified but was part of the B4461 for some time). The northern end of the ex-B4061 was bypassed later and has reverted to its original number (this is the south-facing spur).
