Watching brief by N Randall of SCAU during groundworks involved in the installation of a water pipeline across and to the east and west of the A22. The probable route of the London–Brighton Roman road is postulated to lie below the present route of the A22. No remains of this were exposed in the trench excavated across the A22, but evidence of a succession of 18th–19th century phases of sub-surface road construction was revealed. The stripping of an easement impacted on field boundaries illustrated on tithe and 19th century OS maps, and probable Mesolithic, Neolithic and Bronze Age flints recovered from topsoil deposits are suggestive of prehistoric activity in the vicinity.
