According to the 1840 review another picture "the grand ventilator shaft conveys an equally good idea of the appearance of this vast passage diminishing in the distance into a mere speck. A very picturesque plate of the viaduct over the river Blythe, near the termination of the railroad, has the singular merit of displaying on opposite sides of the same view, a comparison between the ancient and modern modes of bridge building. The massive piers, further secured by buttresses and narrow arches of the ancient fort bridge, afford a curious contrast to the great altitude and extensive span with the slender supports of the modern viaduct."
