This article is about the Class III road numbered C330 maintained by Hampshire Council. For other roads numbered C330, see C330.
Hampshire County Council'sClass IIIC330 follows the old route of the A30 from Sutton Scotney, to Micheldever Station, instead of its current alignment that meets that A303 and A34 at Bullington Cross. This is mostly just a direct route, until we reach the A303 at a T junction... well, a left turn slip access the Westbound carriageway. Here we turn right to stay on the C330, before almost immediately meeting the C29, where the C330 ends. This isn't quite the end of the old A30, however - take the C29 left to pass under the A303, then turn right. For some reason, the final section of the old A30 after this junction, becoming a slip road onto the A303, is designated the C226, whose main section heads towards Steventon, forming a completely unnecessary spur!
