Cruickshank revealed on the "One Foot in the Past" television programme, broadcast on 7 June 1994, that the stone had barely weathered at all. As he explained, "This makes the reconstruction of the arch a tangible reality, ... The arch is made of stone from the Bramley Fall quarry in Yorkshire which is incredibly hard, almost like granite." A section of fluted column was brought up from the river bed, where the stones with "Euston" marked in gold lettering are believed to be located. Other stones are lying in the gardens of those involved in the arch's demolition. The television programme showed at least one large piece being part of the rear wall of a large rockery in one garden.
