The moment the Paraguayan Chaco had been waiting for over decades is just centimeters away. As of May 21, 2026, only 21 meters of concrete separate Paraguay from its first direct land connection with Brazil across the Paraguay River: the International Bioceanic Bridge, also known as the Pantanal Bridge.
Workers from the PYBRA Binational Consortium — comprising Brazilian companies Paulitec Construcciones, Constructora Cidade, and Paraguayan firm Tecnoedil — are laying the final closure voussoirs, the prefabricated concrete segments that will complete the central span of the viaduct. The definitive union between both shores, initially expected for late May, was slightly delayed by heavy rainfall in the region: it is now expected in the second half of June 2026.
A 1,294-meter structure over the river that separated two nations
The bridge spans 1,294 meters in total and will connect the Paraguayan municipality of Carmelo Peralta, in the Alto Paraguay department, with the Brazilian city of Porto Murtinho, in Mato Grosso do Sul. Fully financed by Itaipú Binacional at an investment of approximately USD 93 million, it is the first infrastructure of this kind over the main course of the Paraguay River.
Construction began in 2022. By mid-May 2026, the bridge had reached over 95% cumulative progress, with all piers completed and only the closure of the central span remaining. The complementary 3.8-kilometer road access connecting the bridge to Route PY15 will be operational by November 2026.
The countdown to the complete Corridor
The bridge is the central — but not the only — piece of the Bioceanic Road Corridor, the regional integration megaproject that will connect the Atlantic Ocean with the Pacific across four countries and approximately 2,400 kilometers of roads. The route departs from Campo Grande (Mato Grosso do Sul, Brazil), crosses northern Paraguay through the Chaco, enters Argentina through the provinces of Salta and Jujuy, and reaches the ports of Chile's Norte Grande: Antofagasta, Iquique, and Mejillones.
Progress by country as of May 2026:
- Brazil: road works at 90% completion. The access to Porto Murtinho is already paved and signposted.
- Paraguay (Section 1): the Carmelo Peralta → Loma Plata stretch (270 km) was inaugurated with an investment of over USD 350 million.
- Paraguay (Sections 2 and 3): under active construction. The complete stretch to Pozo Hondo (border with Argentina) is 80% complete according to MOPC.
- Argentina: ongoing improvements on routes in Salta and Jujuy connecting to the Jama and Sico mountain passes into Chile.
- Chile: plan presented by the Boric government covering 22 road sections and improvements at northern port accesses.
President Santiago Peña estimated that the complete corridor will be operational in the early months of 2027. Total committed investment in the corridor exceeds USD 1.1 billion.
Why this reshapes Paraguay's economic map
For 200 years, Paraguay exported almost exclusively eastward — down the Paraguay and Paraná rivers to the Río de la Plata and the ports of Buenos Aires, Montevideo, or Paranaguá. The bioceanic corridor opens for the first time a direct outlet to the Pacific and Asian markets, without depending on third-country infrastructure.
Economic projections are compelling: the corridor can move more than 8.6 million tons per year and generate a direct economic impact exceeding USD 3 billion per year. Paraguay's GDP could grow by at least 1.5% additionally after the corridor becomes fully operational.
When both sections of the central span join above the waters of the Paraguay River in the coming weeks, it will symbolically close a gap that separated two neighboring countries for centuries.
