Lake Pontchartrain Causeway Bridge. National Historic Civil Engineering Landmark. The original 23.86 mile-long structure, which now carries the Southbound traffic, was designed by the firm of Palmer and Baker. When opened in 1956, the structure was the longest bridge in the world by more than 15 miles. In building the bridge, which took just fourteen months, assembly-line, mass-production methods were utilized for the first time in the construction of a bridge. It was designed to employ hundreds of identical, hollow concrete pilings, concrete caps, and pre-stressed deck sections manufactured at an on-shore facility and barged into place. Engineering News-Record acclaimed the project to be "a bold venture requiring unusual foresight, ingenuity and resourcefulness." , Opened: August 30, 1956 Dedicated: October 18, 2003
