IAC undertook archaeological monitoring along the entire route corridor over the course of 10 months; which resulted in the identification of 6 archaeological sites. The sites at Willsgrove, Shanraheen, Salisbury, Ardmore, Smallford and Ardscull were subject to full excavation during this period. The archaeological features represented prehistoric (Bronze Age) and medieval domestic occupation and industry. A single young adult female inhumation burial dating to the medieval period was identified at Shanraheen. Several medieval pits were excavated within the townland of Ardscull and it is suggested that these relate to settlement associated with the nearby motte.
