The bridge we see is likely to be the old San Lorenzo, going toward Sant'Apollinare church and the Piedicastello district, now not existing anymore replaced by a moderd bridge. It was destroyed, as a result of the Allies' bombing over the city, in September 1943 - during what came to be known as "Portela Carnage": out of the overall 400 victims in 80 raids until the end of the war, half of them were killed exactly that day. Less tragic, on the other hand, what we can tell about Dante Square: the buses we see driving by were the first motored way of communication in the city, completely powered by batteries and electricity.
