The Nanay Bridge is a 2.2km bridge crossing the Nanay River, north of the city of Iquitos, Peru.

The bridge will connect the district of Bellavista on the right bank of the Nanay River with the district of Santo Tomas on the left bank.

With a population of almost half a million people, Iquitos is the largest city in the world that cannot be reached by road – tucked in the Peruvian Amazonia jungle, it is currently accessible only by river and air.

Thanks to this project, the city will finally be connected with the rest of the Loreto Region.

The main structure is a cable-stayed bridge with a main span of 242m and total length of 424m. The approach structures are 1.2km long on the right bank of the river, and 320m long on the left bank of the river.

The bridge carries two lanes of traffic and two pedestrian walkways. The roadway has a total width of 12m, and each pedestrian walkway is 1.2m wide.

It uses light-weight composite steel concrete to minimize the use of concrete and to reduce loads transferred to the foundations.

For this project Dextra has supplied 100,000 Bartec couplers for rebar connection and 30,000 headed bars for shear reinforcement of the anchors.

Once completed, it will be the longest bridge in the Country.
