La Barra "wavy" Bridge

ilignelli_1990 · June 14th, 2011, 06:59 AM

La Barra Bridge, located in La Barra, Maldonado, Uruguay, illustrated below, was created by the engineer Leonel Viera (1913-1975) to expand the area of Punta del Este. This pioneered the construction sequence now typical for concrete segment bridges of this type. After placement of the principal cables, precast concrete tiles were placed to form the initial structure. The cables were then prestressed by loading sandbags upon the tiles, followed by final concretization of the gaps between tiles. Removal of the sandbags then compressively stressed the concrete structure, enhancing its stiffness and durability under load. An identical bridge was later constructed parallel to the first.

Yeah they could've done that on the inside of the two bridges at least.
