Robert Maillart의 대표작인 Salginatobel Bridge
Maillart’s best-known structure is the Salginatobel Bridge, completed in 1930. The design was based on the hollow-box arch of the destroyed Tavanasa Bridge, but with refinements: Maillart eliminated certain references to older styles, such as the Tavanasa’s Romanesque stone abutments. He won the competition for the contract because his design was the least expensive of the 19 submitted – the bridge and road were built for only 700,000 Swiss francs, equivalent to some $3.5 million today. Salginatobel was also Maillart’s longest span, at 90 meters (295 feet), and it had the most dramatic setting of all his structures, vaulting 80 meters (262 feet) above the ravine of the Salgina brook. In 1991 it became the first concrete bridge to be designated an international historic civil engineering landmark. [The Revolutionary Bridges of Robert Maillart]
