Notes
The bridges at Schaffhausen (1756-8) and Wettingen (1765-6) were the major works of Hans Ulrich Grubenmann. In this and the preceding drawings, Soane consistently omits the parts (such as the roof of Reichenau bridge) that he considers superfluous or unsuccessful and concentrates on the essential structure.
