The King Carol I Bridge, spanning the Danube at Cernavodă, represented the longest bridge in Europe upon its completion in 1895. Designed by Anghel Saligny, the structure required innovative engineering to reach 4,037 metres in total length, eventually securing its place as a definitive achievement in late nineteenth-century infrastructure development and civil engineering.
Early Education and Professional Formation
Born in 1854 in Șerbănești, Saligny began his formal studies at a boarding school in Focșani before attending the Unirea high school. He continued his secondary education in Potsdam, Germany, in 1869. His technical training culminated at the Technische Hochschule in Charlottenburg, Berlin, where he studied from 1871 to 1874. During this period, he attended astronomy courses at Friedrich Wilhelm University, learning under physicist Hermann von Helmholtz. His engineering foundation was further bolstered by teachers Johann Wilhelm Schwedler and Otto Franzius.
Contributions to European Railway Infrastructure
Before his major Romanian projects, Saligny worked on railway construction in Saxony, specifically the Cottbus-Frankfurt an der Oder line, and performed hydraulic works in northern Prussia under Georg Christoph Mehrtens. Returning to Romania in 1875, he entered the Service of Bridges and Roads. In 1883, he became head of the Bridges and Railways Service, replacing collapsing wooden structures with durable iron alternatives. His notable projects included the 430-metre bridge at Cosmești over the Siret River and the Adjud-Târgu Ocna railway line.

Saligny pioneered the use of reinforced concrete for industrial storage. Between 1884 and 1889, he designed the world's first silos constructed from this material, located in the ports of Constanța, Brăila, and Galați. These facilities utilized prefabricated wall plates, floor slabs, and mechanized assembly techniques. In Constanța, he also designed specialized infrastructure for the export of oil and grain, effectively modernizing the nation's port capabilities.
The Cernavodă Bridge Project
Tasked by the Romanian government to design a bridge over the Danube after previous proposals were rejected, Saligny created a structure that rose 30 metres above the water to accommodate maritime traffic. The bridge featured four openings of 140 metres and a central span of 190 metres. On its opening day, the project underwent a rigorous stress test involving a locomotive convoy traveling at 85 km/h. This bridge solidified his reputation as a premier civil engineer.
Political and Academic Influence
Beyond technical projects, Saligny served as a professor at the School of Bridges and Roads in Bucharest from 1884 to 1914. A founding member of the Bucharest Polytechnic Society, he eventually served as Minister of Public Works. In 1892, he joined the Romanian Academy, later serving as its president from 1907 to 1910. He remained active in engineering professionalization until his death in Bucharest in 1925.
