Magnetic susceptibility, detailed magnetometry, and resistivity survey by D Sabin of Stratascan and a programme of fieldwalking by N Hall of ASE along sections of the proposed route of the A24 between Capel and Horsham. Within the Surrey section of the route, a number of anomalies and flint scatters were located. A watching brief carried out by K Sayer of PCA during the excavation of geotechnical trial pits along the proposed route revealed three possible features, one of which contained a fragment of burnt flint and a sherd of medieval pottery.
