From Brazilian customs, the road crosses the Ponte Tancredo Neves into Argentina. Opened in 1985, it replaced the small boats that had ferried people and cargo across the Rio Iguaçu for decades from a crossing point once known as Porto Meira, and painted half in Brazilian colors and half in Argentine, it's since become the busiest land border crossing in the country. It's also notoriously unpredictable — a Friday afternoon crossing can mean a ten-minute formality or a wait stretching into hours, with no real way to know in advance. Worth checking a live queue-tracking app like Puenty before committing to a departure time, and worth holding the whole afternoon loosely: there's nothing waiting on the other side tonight but dinner, so there's no real cost to letting the border set its own pace.
Whenever the crossing clears, the road settles into Puerto Iguazú — a smaller, quieter counterpart to Foz do Iguaçu, oriented around the same river and the same falls, but with its own rhythm. Tonight is simply for arriving, whatever time that turns out to be, and resting up before the Argentine side of the falls — a very different vantage point on the same water — becomes tomorrow's focus.
