Design of three road bridges with cantilevered pedestrian walkways and two reinforced concrete works for vehicle passage, projecting two 3.5 m wide lanes. The project includes the following:
- Factory work 1: 11 metres of light, two holes of 4.75×3.5 m, 0.5 metres of thickness in strips and slabs
- Factory work 2: 6 meters of light, with dimensions of 5×4 meters, 0.5 meters of thickness in strips and slabs
- Bridge over the Mitong River: isostatic metal lattice of intermediate panel on reinforced concrete piles. Light of 102.33 meters distributed in 4 compartments.
- Bridge over the Toche River: isostatic metal lattice of intermediate panel on reinforced concrete piles. Light of 39,642 meters of a single span
- Bridge over the Mitemele River: isostatic metal lattice of intermediate panel on reinforced concrete piles. Light of 77,364 meters distributed in 3 spaces.
