The typology chosen to save the river Ene, a tributary of the Amazon, is s cable-stayed bridge with a concrete section and spans distribution of 95 + 270 + 135 + 135 + 270 + 105 m accompanied by a 384 m long access viaduct divided into 30m spans.
This solution combines all the established conditions with a design that respects its environment, of great ecological and environmental value, and represents an architectural milestone for Peru.
The chosen layout reduces the risk of scour, by reducing the number of pillars with respect to the other alternatives analysed, it also has a design that remains valid even if the main channel of the Ene River moves to the right bank, or even if with the time the central island disappeared due to the dynamics of the river.
The deck of the cable-stayed bridge has a total width of 20.17 m, including the aerodynamic finishing of the edges and the reserve of space for the anchoring of the stay cables. Within the useful surface of the deck, there will be 2 sidewalks of 1.50 m separated from the traffic by barriers of 0.60 m wide. In the platform of the road there will be 2 lanes of 3.60 m, 2 berms of 3.00 m that will be separated 0.60 m from the face of barriers.
