After the 1930s Basingstoke bypass, the M3 changes direction (between North Waltham and Popham, at the Popham Interchange) the A303 takes over for the A30 losing continuity. From Sutton Scotney village the A30 runs parallel to the latter road as-the-crow-flies to north-east of Honiton, Devon passing through towns Stockbridge (where it meets its first substantive river since the Thames, the Test) and its trout fishing centres, Shaftesbury, Sherborne, Yeovil, Crewkerne and Chard. Between Stockbridge and Shaftesbury it enters the cathedral city of Salisbury.
