This article is about the original A273 serving Laughton in East Sussex.
For the current A273, running from Haywards Heath, see A273
(former A273) east of Ringmer
The A273 number was originally used for a road in Sussex between the then-A265 (now B2192) at Ringmer and the A22 at Holmes Hill. The road was rural; the largest place en route, Laughton, is still not very big.
The A265 was downgraded in this area in the 1960s, taking the A273 with it; our road is now the B2124. The A273 number had been reused nearby within a few years.
