The Integration Bridge between Foz do Iguaçu and Presidente Franco, a stayed structure of 760 meters inaugurated in December 2025, cost R$ 1.9 billion and should relieve the saturation of the Friendship Bridge, but operates with restricted traffic because the accesses on the Paraguayan side are still under construction.
The bridge that was supposed to transform logistics in the triple border between Brazil, Paraguay, and Argentina is ready, but it does not operate at the capacity for which it was designed. Inaugurated in December 2025 as the second road link between the two countries in the Foz do Iguaçu region, the R$ 1.9 billion structure remains underutilized because the road system that should connect it to the rest of Paraguayan territory has not yet been completed. The traffic released so far is limited to empty cargo vehicles during designated time slots, a condition that prevents the bridge from fulfilling its role of redistributing the flow that has suffocated the neighboring Friendship Bridge for decades.
The situation exposes a recurring problem in large infrastructure projects in South America: the bridge does not solve anything on its own. On the Brazilian side, the connection has been practically resolved with the Perimetral Leste, a 14.7 km highway that directly links the bridge to BR-277, diverting heavy traffic from the urban center of Foz do Iguaçu. On the Paraguayan side, however, full operation depends on the completion of the Del Oeste Metropolitan Corridor, which is over 30 km long, and the construction of a new crossing over the Monday River, scheduled for 2027. Until these components are ready, the R$ 1.9 billion bridge remains a partial solution to an incomplete system.
Why was the bridge built if there was already a connection between Brazil and Paraguay
The Friendship Bridge, inaugurated in 1965, concentrated practically all the flow between the two countries in the triple border region for six decades. Currently, about 100,000 people and 45,000 vehicles cross the structure every day, a volume that has turned the original connection into a bottleneck and pressured not only the crossing but the entire urban system of Foz do Iguaçu and Ciudad del Este. Constant queues, delays in cargo transport, and loss of logistical efficiency have begun to directly affect the economic competitiveness of the region.

The bridge of R$ 1.9 billion was conceived to function as a strategic alternative, not as a substitute. The goal is to redistribute part of this flow between two crossings instead of concentrating everything at a single already saturated point, reducing waiting times, operational costs, and the urban wear caused by heavy traffic in city centers. The problem is that a bridge only fulfills this function when it is connected on both sides, and in the case of the Integration, the Paraguayan side remains an incomplete link in the chain.
The dimensions of the bridge and what engineering delivered
In structural terms, the bridge is fully completed and operational. The work follows the cable-stayed model, in which steel cables fixed to tall towers support the deck without the need for intermediate pillars in the riverbed, a solution that allows for spanning large distances and ensuring the continuity of navigation on the Paraná River. The two main towers reach about 190 meters in height and serve as the core of the system, distributing the loads of the deck through the cables that fan out.
The free span of 470 meters is one of the largest in Latin America and represents almost half a kilometer of suspended bridge without any support in the central section. The execution over the Paraná River required segmented assembly with floating equipment and high-precision lifting systems, as each section of the deck needed to be fitted with minimal tolerances to not compromise the overall alignment. The foundations use deep piles designed to transfer the weight of the bridge to more resistant layers of the subsoil, considering the geological conditions of the riverbed. The total investment of R$ 1.9 billion covered both the main structure over the Paraná River in the Foz do Iguaçu region and the accesses on the Brazilian side.
What is missing for the bridge to really function
The list of pending items is known and has a deadline. On the Paraguayan side, the completion of the Del Oeste Metropolitan Corridor, a highway of over 30 km that will connect the bridge to the country’s road system, is the most critical stage, followed by the construction of the crossing over the Monday River, a complementary work scheduled for 2027. Without these two pieces, the trucks crossing the bridge arrive on the other side and find insufficient infrastructure to accommodate them, a scenario that practically nullifies the logistical gain that the crossing should provide.
The migratory and customs checkpoints also need to be consolidated before the bridge operates at full capacity. The gradual release of traffic, restricted to vehicles without cargo and during specific hours, is precisely the strategy adopted to adjust the inspection and security systems before opening the crossing to the actual volume it was designed to support. Finalizing the Paraguayan accesses, expanding the release for cargo transport, and integrating the customs systems of both countries are steps that will determine whether the bridge will fulfill its function in 2026 or remain as a completed structure waiting for a system to accompany it.
What the R$ 1.9 billion bridge can represent when it is operational
If fully integrated into the road system on both sides, the bridge has the potential to reorganize the logistics of the entire region. The redistribution of traffic between two crossings would reduce queues, shorten waiting times, and decrease operational costs for carriers who today lose hours at the Friendship Bridge, an impact that extends from freight costs to the final price of products consumed in Foz do Iguaçu and in the border cities. In addition to the direct effect, the structure fits into a broader context of South American logistics corridors, potentially serving as an exit point for routes that continue through Paraguay towards the bi-oceanic axis.
For now, however, the bridge remains a symbol of a recurring contradiction in large infrastructure projects. Engineering has solved the crossing, the cables support the concrete, the towers dominate the landscape over the Paraná River, but the system that should give meaning to all this has not yet kept pace with the main construction. Until the accesses are ready and traffic is released without restrictions, Brazil will have a bridge costing R$ 1.9 billion that functions as a postcard and not as a logistics corridor.
And you, do you think the bridge will operate at full capacity by 2026 or will the complementary works delay everything? Have you crossed the Friendship Bridge and know what the congestion is like? Leave your opinion in the comments.
