A27 • B2123

Falmer Interchange is a modified dumbbell interchange in Sussex, with the slip road on to the A27 westbound being on the eastern side of the B2123. On the northern side there is the main entrance to the University of Sussex and a normal roundabout, but on the south side is a large mini roundabout with filter lanes.

The junction was built on the village of Falmer which was split in two by the expansion of the A27 from single carriageway to a dual carriageway in 1981. The old road took the A27 up a steep hill to meet the B2123 at a crossroads after which it became Middle Street (now residential), whereas the new road is in a cutting at a much lower height, leaving the job of climbing the hill to the sliproads. The looped sliproads allow the junction to fit on top of Falmer Tunnel, the railway's tunnel under Falmer Hill, saving a complicated bridging job.

Brighton and Hove Albion's American Express Community Stadium (AMEX) was built next to the interchange in 2011. The junction is now frequently used by lots of cars and buses on match days.

Unusually for a fast dual carriageway (but understandable given the history), this junction features a pair of bus stops and associated facilities including footpaths and grit bins: one on the eastbound onslip and one on the westbound mainline. The sliproads are signed as 'one way' roads.
