Following the construction of a bypass around Basingstoke, the route of the A30 was changed on 1 April 1933 to run by Sutton Scotney and Stockbridge, rejoining the original route at Lopcombe Corner east of Salisbury. An alternative route, the A303 was created out of existing roads at the same time between Micheldever Station and the Blackdown Hills, that followed the basic course of Hanning's New Direct Road. The A30 remained the principal route between London and Exeter, until the A303 became a trunk road in 1958, receiving central Government funding and relegating the parallel A30 to a local road.
