|Route outline (key)|
In 1922 it started on the A272 at Piltdown before heading to Maresfield. Following a short multiplex with the A22 it continued east via Buxted to end on the A267 at Poundford. In the 1960s this road swapped numbers with the section of the A272 east of Piltdown; the B2102 was extended beyond the original eastern end of the A272 so that it still ended on the A267.
The 1960s B2102 started on the A272 at Piltdown and headed into Uckfield to meet the A22. This road was declassified following construction of the Uckfield bypass and so the B2102 now starts on the A22 Uckfield bypass.
Apart from a modern extension connecting the Uckfield bypass to Uckfield High Street, the B2102 follows former sections of the A272 (from Uckfield to Blackboys) and the A265 (from Blackboys to Cross in Hand), with a short 0.8 mile branch which was once the A268 (and later a spur of the A267) at the latter place.
