Musmeci Bridge

The “Viadotto dell’Industria”, also known as "Bridge over the Basento" river or Musmeci Bridge, is a bridge in Potenza, Basilicata, Italy, that connects the Potenza city center exit on the Sicignano-Potenza motorway with the main access roads in the southern part of the city.

Designed by the Italian engineer Sergio Musmeci in 1967, and built between 1971 and 1976, the bridge perfectly incarnates Musmeci's architectural theories. The structure cost about 920,000,000 Italian liras.

The structure's uniqueness is due to its construction: it is made of only one membrane of reinforced concrete molded to form four contiguous arches.
