# South American Bioceanic corridor & river projects > Live situation record from CLSTR: https://clstr.news/situations/paraguaybrazil-bioceanic-bridge-project > Updated: 2026-08-10T04:58:31.000Z. Sources: 50. Developments: 17. The Bioceanic Corridor and associated river navigation projects continue to expand through August 2026. Key infrastructure developments include the near-completion of the Brazil-Paraguay bridge (to be named ‘Ponte Heitor Miranda dos Santos’) and the inauguration of Argentina’s El Pindó bridge. Paraguay has also begun paving the final 52km of its Bioceanic Corridor toward the Argentine border and approved a US$286 million JICA-financed road project linking Yabebyry to Pilar. In the energy sector, the Yacyretá Aña Cuá hydroelectric expansion is progressing, with civil works reaching up to 50% completion. Additionally, Paraguay has proposed a 1,000km Bioceánico gas pipeline to link Brazil with Argentina’s Vaca Muerta field. Rail projects are also advancing, including a proposed US$9.6 billion corridor between Mendoza and the Chilean coast, and a broader Brazil-Peru rail initiative. River navigation remains a central focus and a point of contention. Argentina finalized a 25-year concession for the Vía Navegable Troncal, awarding it to the Jan de Nul-Servimagnus consortium. This decision has sparked significant controversy; critics and the Buenos Aires provincial government allege the tender lacked transparency and may increase costs for exporters. Meanwhile, the Argentine Federation of Shipping Companies (FENA) has opposed deregulating cabotage laws, and Paraguay’s ANNP has dismissed rumors of toll increases. Regionally, Brazil and Paraguay are negotiating a Paraguay River waterway auction for 2027, while trilateral efforts aim to strengthen the Paraguay-Paraná Hydrovía as a sovereign export corridor. ## Timeline ### 2026-08-10: Paraguay begins paving final 52km of Bioceanic Corridor Paraguay has begun paving the final 52 kilometers of the Bioceanic Corridor toward the Argentine border, a strategic project linking Pacific and Atlantic ports. 5 sources. https://clstr.news/cluster/paraguay-begins-paving-final-52km-of-bioceanic-corridor ### 2026-07-26: Hidrovía waterway embroiled in Argentine scandal and regional conference Argentina’s Economy Minister Luis Caputo is accused of steering a secretive Hidrovía concession, while Bolivia prepares to join a regional conference on the waterway’s governance and development. 3 sources. https://clstr.news/cluster/argentinas-luis-caputo-backs-controversial-paraguayparan-waterway-concession ### 2026-07-23: Paraguay launches $286 million bioceanic corridor to connect Brazil and Argentina with Pacific ports Paraguay approved a $286 million Japan‑funded bioceanic corridor, a 170 km concrete road linking Brazil and Argentina to Pacific ports, with construction set for 2027. 2 sources. https://clstr.news/cluster/paraguay-launches-286-million-bioceanic-corridor-to-connect-brazil-and-argentina-with-pacific-ports ### 2026-07-17: Paraguay and Argentina Advance Yacyretá Aña Cuá Hydropower Expansion Paraguay and Argentina’s Yacyretá project is installing three turbines at Aña Cuá, boosting capacity by ~10 % with 800 workers, US$600 M investment, and full operation expected by 2029. 4 sources. https://clstr.news/cluster/paraguay-and-argentina-advance-yacyret-aa-cu-hydropower-expansion ### 2026-07-16: Argentina's Milei rejects $270 million loan guarantee, province challenges river navigation concession Milei's government refused a $270 million loan guarantee for Buenos Aires province’s river‑basin project, while the province denounced a 25‑year river navigation concession as irregular and costing exporters an 7 sources. https://clstr.news/cluster/argentinas-milei-rejects-270-million-loan-guarantee-province-challenges-river-navigation-concession ### 2026-07-13: Paraguay and Argentina dispute cabotage and tolls on Paraguay‑Paraná waterway Argentina's shipping federation opposes opening cabotage to foreign vessels, while Paraguay’s navigation authority rejects talks of a toll hike on the Paraguay‑Paraná waterway, keeping fees at US$1.30/ton amid 2 sources. https://clstr.news/cluster/paraguay-and-argentina-dispute-cabotage-and-tolls-on-paraguayparan-waterway ### 2026-07-07: Argentina awards private concession for Paraná‑Paraguay waterway Argentina's government signed a 25‑year private concession for the Paraná‑Paraguay waterway, granting Jan de Nul‑Servimagnus operation rights, a 13.5 % toll cut, and state supervision, amid controversy over the 6 sources. https://clstr.news/cluster/argentinas-paran-paraguay-waterway-privatized-toll-cut-135 ### 2026-07-06: Brazil, Paraguay set July talks on Paraguay River waterway auction Brazil and Paraguay will meet in late July to push forward the Paraguay River waterway auction, which requires agreement with Bolivia.
