The width of the bridge between parapets is 60 ft., except across the centre span, where it is 49 ft.
In several cases there is a canal in the centre lined with stone, and protected by low parapets or banks, while almost every street and square is fringed with trees.
Most of the houses, and especially those of the planter aristocracy, are massively built of stone, with large grated windows, flat roofs with heavy parapets and inner courts.
Work on the bridge proceeded quickly as Jack Pocock, expert bricklayer, built up the new parapets with considerable skill.
In Victorian times replacing the stone parapets with cast iron, themselves replaced with masonry in the 1920's.
