Following this success, he joined the firm of Campenon-Bernard and went on to design several prestressed bridges.

His largest structure was the Plougastel Bridge with three identical spans of 180 m (592 ft) each, completed in 1930. Here he studied creep in more detail, and developed his ideas of prestressing , taking out a patent in 1928. Although Freyssinet did much to develop prestressed concrete, he was not its inventor. Other engineers such as Doehring had patented methods for prestressing as early as 1888, and Freyssinet's mentor Rabut built prestressed concrete corbels . Freyssinet's key contribution

4623-420: Was founded by François I in the form le Hable de Grace then Ville de Grace in 1516, two years before its official founding. The learned and transient name of Franciscopolis in tribute to the same king, is encountered in some documents then that of Havre Marat , referring to Jean-Paul Marat during the French Revolution but was not imposed.
