This article is about the original B3085 heading north from Salisbury.

(former B3085) at Boscombe
The number B3085 was originally allocated to the road heading from St Thomas's Bridge, Salisbury, northeast along the valley of the River Bourne to reach the then-A344 at Parkhouse Corner between Cholderton and Shipton Bellinger.
It was quickly upgraded to Class I, becoming the A3052 on 1 April 1924. In 1935 it became part of a rerouted A338, which it remains.
