Le projet Viaducto del Manglar est un projet de pont de 5,3 km enjambant la Ciénaga de la Virgen (marais), au nord de la ville de Carthagène, en Colombie. Le projet vise à réduire les embouteillages à la sortie de la ville dans la Zona Norte (zone nord).
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.
