The “Viadotto dell’Industria”, also known as "Bridge over the Basento" river or Musmeci Bridge, connects Potenza city centre exit on the Sicignano-Potenza motorway with the main access roads in the southern part of the city, which is in Italy.
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. The concrete sheet is shaped into a “finger-like” structure, which supports the whole bridge, and it is also used as a pedestrian walkway.
