This article is about the original A511 from Atherstone to Burton upon Trent. For the current A511, formerly the A50 from Markfield to Foston, see A511. For the once proposed A511 linking the M6 and Wigan, see A511 (Wigan).
The original allocation of the number A511 was to a medium-length road in the East Midlands.
Starting on the A5 in the centre of Atherstone, the road headed north through Sheepy Magna to reach Twycross, where it bore to the left. It continued vaguely northwards, however, passing to the west of Swadlincote and eventually reaching Burton upon Trent, where it ended on the A50 to the east of town.
In 1935 the Atherstone to Twycross section was reclassified as the B4116, whilst the section from Twycross to Burton became part of a northern extension of the A444. The A511 road number became disused but reappeared in the same area in the 1990s: what was the A50 at its northern end is now the A511.
