The Bioceanic route is an international project that aims to link the Atlantic and Pacific Oceans through a highway that will cross Chile, Argentina, Paraguay and Brazil, with the aim of stimulating freight traffic. As it passes between Paraguay and Brazil, the route will link the towns of Carmelo Peralta (Paraguay) and Porto Murtinho (Brazil), having to cross the channel of the Paraguay River at that point.
The bridge designed to cross this great river comprises three different sections, the first is an access viaduct on the right bank of the river (Paraguay) of 305 m in length, a cable-stayed section of 620 m in length and a viaduct of 275 m in the left bank of the river (Brazil). The main section, the cable-stayed, serves a 195 m x 29 m navigation channel for an elevation of the mean level of the river in a return period of 100 years.
The cable-stayed section, centered on the riverbed, has a main span of 350 m and two retaining sections of 135 m on both banks. The towers support a double plane of stayed cables with a hybrid arrangement between the harp and fan system. The access viaducts are conceived as simple supported beams on concrete piles. Each deck has a length of 30 m and is made up of 8 pre-tensioned beams. The 20 m wide cross section accommodates a road with two 3.6 m lanes, one for each direction of traffic.
