M20 CORK TO LIMERICK MOTORWAY SCHEME, IRELAND
Rubicon surveyed 235 ha at 110 sites along an 86km route on behalf of the National Roads Authority. This was one of the largest geophysical surveys ever undertaken on an infrastructural scheme in Ireland. Eight sites of ‘High Archaeological Potential’ were identified including three ringforts, a moated site, an undefined structure, a possible Iron-Age field system and a possible deserted medieval village. Magnetic gradiometry was the principle method used. The result informed the selection of targeted areas for earth resistance survey.
