The Paseo del Bajo Project arises from the desire of removing heavy vehicle traffic at street level in an area of great urban and tourist quality of the City of Buenos Aires, such as Puerto Madero. To get this, the project runs from the 25 de Mayo Highway to its junction in the north with the Arturo Illia Highway.
The new infrastructure is 7.1 km long, in its central area presents an open trench section, with two complex links made up of pre-cast girder viaducts, which serve for the connection with the existing elevated highways. The infrastructure has liberated 60,000 m2 of public spaces for the enjoyment of residents and tourist along its development.
Arenas & Asociados is responsible for the project and technical assistance to the construction company of the structures that connect with the pre-existing highways, with a global length of viaducts of more than 3,500 m.
To meet the short deadlines, we developed the “VICBeam” software, which, in addition to the 3D rendering of all elements, provides geometry plans at construction level and reinforcement sheets.
The urban layout dictated the geometry of the bridges, which are curved in most of their length. The viaducts present isostatic decks of prestressed beams of 1.40 m deep, with extreme diaphragms on which a 20 cm thick reinforced concrete slab is placed. To reduce the number of joints between the deck and provide the best ride comfort, Thormack type joints were arranged, interspersed between the conventional road joints.
