Nicolás Avellaneda Bridge, Liftable transport bridge in La Boca, Argentina.

Nicolás Avellaneda Bridge is a 1,650-metre road bridge over the Riachuelo, linking La Boca in Buenos Aires with Isla Maciel in Avellaneda. Its red steel truss superstructure, with diagonal cross-bracing, rests on two light-grey concrete towers. The central lift span rises to give a clearance of 43 metres, while the closed bridge leaves 21 metres for navigation.

Construction took place between 1937 and 1940 as an engineering project to link Buenos Aires with surrounding territories. The bridge became an important infrastructure milestone for regional connectivity.

The bridge connects La Boca, a neighborhood shaped by Italian immigration, with the industrial areas across the river. It remains a daily crossing point where people experience the character of both sides.

Pedestrian stairs and walkways run alongside the vehicle lanes, making it accessible for people on foot as well as traffic. When ships pass through, the bridge rises and traffic temporarily stops, so plan for potential delays.

Originally, the bridge included a transporter gondola system designed for wagons to cross without the main structure moving. This overhead shuttle made it a clever engineering solution for its era.
