San Roque González de Santa Cruz Bridge

San Roque González de Santa Cruz Bridge is a road and rail crossing over the Paraná River linking Argentina and Paraguay, carrying both cars and trains on the same structure. The bridge uses cable support and consists of a central span over the water with approach sections on either side to reach the two cities.

Construction of the bridge started in 1981 as a compensation project related to a major dam built in the region. It opened to traffic in 1990 and created the first permanent land link between these two countries.

The bridge takes its name from a Jesuit missionary who founded religious communities in this border region centuries ago. For people living on both sides, it represents a shared spiritual heritage that shaped the development of these territories.

The bridge is open to cars, trucks, and trains every day with clearly marked lanes for both directions. You will need your travel documents as this is an international border crossing, and wait times for inspections are common during busy periods.

An Italian engineering firm led the construction of this bridge as a joint project, creating an innovative solution to carry both road and rail traffic on a single structure. This dual-purpose design was technically noteworthy when completed and remains uncommon for river crossings between countries.
