The Musmeci Bridge over the Basento river, on the western approach to Potenza, is the city's most striking sight and a landmark of post-war Italian engineering. Built between 1971 and 1976, it consists of a single thin reinforced-concrete shell that flows under the deck in a sinuous, four-lobed curve — the kind of shape you would expect to see in a museum of modernist sculpture.
You see it best from below, from the riverside park or driving in along the SS407 Basentana. Worth a deliberate detour if you have any interest in modern architecture.
