Lake Pontchartrain bridge
Freyssinet
By 1956, STUP (the future Freyssinet) had established a strong reputation in civil engineering structures. The State of Louisiana chose Eugène Freyssinet's company to play a consulting role on the construction of the longest bridge in the world. The spans for this 38-kilometre bridge, were prefabricated on shore. The bridge crossed the Lake Pontchartrain wildlife reserve.
