Southerham Roundabout marks the eastern end of the D2 section of the A27 from Brighton. Also the A26 joins the A27 here and runs along the A27 eastwards to the next roundabout. The roundabout has three arms:
- North - A26 - S2
- East - A27 (A26) - S2+1
- West - A27 - D2
The junction was first planned in the early 1970s when the Lewes Bypass was proposed following the abandonment of the inner relief road scheme. An early plan shows a trumpet but this was changed to a roundabout by the time it opened in 1978.
In the early 1990s proposals were made to dual the A27 between Lewes and Polegate. Southerham Roundabout would be grade separated as part of this scheme. The layout was refined until the layout shown here was announced in 1993. This scheme was later withdrawn and the roundabout remains to this date.
In 2007 smaller scale improvements were made to the section between Southerham and Beddingham which involved adding a filter lane for westbound traffic to avoid the roundabout.
