 | | Robert Stevenson to cross the Menai Straits is intended to be formed of iron, and to be suspended from massive stone piers, as shown in the engraving. |
 | | A walk across the bridge gives a sense of enormous strength in the structure, and although the lines of the structure are wholly straight, or diagonal, its extent, its lightness, and its ever-shifting lines give it a picturesque effect. |
 | | The quantity of wrought iron used, in-cluding many girders from the old bridge, is 19,000 tons; of steel, 3500 tons; and of cast-iron, for the piers, 2500 tons; with three million rivets, averaging five inches in length; ten million bricks, weighing 37,500 tons; and 70,000 tons of concrete. |
