- Robert and James Adam office drawings
Robert Adam was later commissioned to build another bridge to carry the approach from his new gatehouse across the river Thames. The bridge was executed with alterations from Adam volume 51/10, which is also illustrated in two engravings in volume I of The works in architecture of Robert and James Adam.
Adam volume 51/11 shows Adam's unexecuted scheme for a ruinous bridge. This is an interesting conceit of a bridge desgined to appear as if it were falling down with age.
