On each side of the arch is a rectangular portal for the pavement. On both sides of the portals are attached unfluted monolithic Doric half-columns at each corner. Across the top of the structure is a dentilled cornice which carries a panelled parapet. In constructing Northgate, Harrison used "as few and as huge stones as possible".
