Which bridge was Calatrava's first completed bridge?

Calatrava’s first completed bridge was the Bac de Roda Bridge in Barcelona.

Also called the Calatrava Bridge, Bac de Roda links Barcelona’s Sant Andreu and Sant Martí districts across major railway approaches. Calatrava designed it in the mid-1980s, and construction took place from 1984 to 1987. Its completion established the structural language that became strongly associated with his later bridges: dramatic white arches, angled supports, and sculptural pedestrian approaches.

The bridge was part of Barcelona’s wider urban transformation before the 1992 Summer Olympics. It helped reconnect neighborhoods divided by railway infrastructure and turned a previously degraded area into a more prominent civic space. The bridge opened in 1987, several years before the Olympics themselves.

The alternatives are all genuine Calatrava projects, which makes them tempting. The Alamillo Bridge in Seville and the Lusitania Bridge in Mérida came later, while Ponte della Costituzione in Venice opened much later, in 2008. Bac de Roda is therefore the canonical answer when the question asks for his first completed bridge.
