A substantial swathe across Brands Hill is to be affected by the dualling of the A435. Since the precise location of archaeological remains within this area is uncertain a magnetic susceptability survey, taking readings at 20m centres, was carried out along the road line … was supplemented with a magnetometer survey (readings at 1m centres) to further examine the areas of enhanced magnetism.
