4” x 6” black and white glossy photograph pasted on 8 ½” x 11” sheet of paper (typed caption) Bridge over the Thur, near Felsegg, Canton St. Gall, Switzerland. 1933. Robert Maillart, engineer. Two parallel three-hinged arches of 226-foot span. No bridge of Millart’s (i.e. Maillart) is more assertive of strength than this light span over the Thur. Characteristic of his later work are the powerful concisely defined, highly differtiated (i.e. differentiated) shapes – the pointed arch, the straight-drawn outer edges of the arch, ribs, the splayed slab-supports of the approaches. Every part is alive and at work. The X-shaped abutment-joints of reinforced concrete, more economical than conventional steel hinges contribute a great deal to the sense of unity and continuity of structure.
