|Route outline (key)|
The B3048 is an unofficial Andover eastern bypass.
It starts on the A343 in Hurstbourne Tarrant and proceeds southeastwards along Church Street, soon leaving the village. The road follows the Bourne Rivulet, a tributary of the River Test, through Stoke and St Mary Bourne and passes under the West of England Main Line.
The B3048 crosses the Bourne Rivulet and enters Hurtsbourne Priors where it crosses the B3400 (former A30) via an offset crossroads. This marks the original northern end of the B3048 but the road was quickly extended north along the previously unclassified section already mentioned. About a mile further on it reaches the River Test itself (the Bourne Rivulet swung east to meet it but the B3048 took a straighter route).
The B3048 then follows a very winding course through East Aston, Longparish, Middleton and Forton before reaching an unusual interchange with the A303. B3048 traffic has to TOTSO twice either side of the overbridge; stay on to turn left onto the A303.
