Viaducto del Manglar 项目是一个全长 5.3 公里的桥梁项目，横跨哥伦比亚卡塔赫纳市北部的 Ciénaga de la Virgen（沼泽）。该项目旨在减少 Zona Norte（北部地区）出城时的交通拥堵。
For this project, Dextra supplied its Headed Bar systems, used into large prefabricated caissons, in order to reduce the reinforcement congestion. That application allow designers to lower the steel/concrete ratio in eleemnts. Headed Bars are also much easier to install, as they fit on straight bar that can be inserted in the case easily.
