Héroes del Chaco Bridge, Cable-stayed bridge in Asunción, Paraguay

The Héroes del Chaco Bridge is a cable-stayed bridge over the Paraguay River linking Asunción with Nueva Asunción. Its structure section is 2,609 metres long, comprising a 600-metre cable-stayed stretch with a 300-metre main span and a 2,009-metre viaduct, reached by a 4,800-metre road approach from the Costanera roundabout toward Route PY09.

In December 2019 the contract was awarded to the Unión Consortium, formed by CDD Construcciones S.A. and Constructora Heisecke S.A. The groundbreaking took place on 12 June 2020, the 85th anniversary of the signing of the Peace of Chaco, which ended the Chaco War with Bolivia. The bridge was inaugurated by President Santiago Peña on 3 March 2024 and opened to traffic at 00:00 on 4 March.

The bridge is named after soldiers who fought in the Chaco War, chosen through public participation by local communities. It serves as a daily reminder of this historical chapter in Paraguay's past for everyone crossing it.

The bridge is open only to light and medium vehicles up to 3,500 kg; heavy trucks must keep using the Remanso Bridge, about 8 km upstream. The deck carries four vehicle lanes plus separate paths for cyclists and pedestrians. It links the Costanera de Asunción roundabout with Nueva Asunción and continues toward Route PY09.

The bridge's 600-metre cable-stayed section has a 300-metre main span, and its full 2,609-metre structure is reached by a 4,800-metre road link from the Costanera roundabout. It is one of only three bridges joining Paraguay's eastern and western regions, alongside Nanawa and Remanso.
