Pietro Nenni Bridge

The Pietro Nenni Bridge connects the Flaminio and Prati districts across the Tiber River with three concrete spans that support both cars and the Metro Line A tracks. After crossing the river, the railway descends underground at Via Cesare Beccaria to continue its route beneath the city.

Construction began in 1969 and was completed in 1972, though the official opening took place in 1980 after extensive testing periods. The bridge was named shortly after the death of Pietro Nenni, an influential socialist politician who shaped Italian politics.

Named after Pietro Nenni, a socialist leader who influenced Italian politics, the bridge received its designation one month after his passing in 1980.

Visitors can walk across the bridge or ride the metro to experience the exposed tracks up close as they cross the river. The best views of the structure are from the Tiber's banks or from the surrounding streets at ground level.

This is the only section of Rome's Metro Line A that runs above ground, exposing the transportation route across the water for all to see. This visible segment gives passengers an unusual view of the river during their regular train ride.
