Ponte Pietro Nenni Rome
Though the Pietro Nenni Bridge was constructed between 1969 and 1972 it was not inaugurated until 1980. Since the socialist leader Pietro Nenni died around that time, the bridge was named after him, though many people still refer to it by the name it was originally planned to get, the Ponte della Metropolitana.
It was designed by the architects Luigi Moretti and Silvano Zorzi.
The Ponte Nenni is 121m wide and has a width of more than 25m. It is made of reinforced concrete and is the only point in the central part of metro line A that is above ground.
