Existing Pottagh Bridge consisted of a three-span, simply supported steel plate Girder Bridge with intermediate piers which carries the Coleraine to Derry/Londonderry Railway line over the Articlave River to the East of Castlerock. As part of the Coleraine to Londonderry Track Renewal Project Works, the existing bridge was replaced.
