The “Viadotto dell’Industria” (Industry viaduct),{{cite book|author=Fausto Giovannardi|title=Sergio Musmeci. Strutture fuori dal coro|year=2010|publisher= Giovannardierontini|url=http://www.giovannardierontini.it/files/sergio_musmeci.pdf|language=it}} also known as "Bridge over the Basento" river or Musmeci Bridge,{{cite web|title=Potenza - Galleria Immagini: Ponte Musmeci|website=APT Basilicata|url=http://www.aptbasilicata.it/Galleria-Immagini.1432+M54cf5effbd3.0.html|access-date=2015-03-11|language=it}} 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,{{cite journal|author=Luigi Spinelli|title=When infrastructure becomes landscape|journal=Domus|date=2007-10-17|url=http://www.domusweb.it/en/architecture/2007/10/17/when-infrastructure-becomes-landscape.html}} and built between 1971 and 1976, the bridge perfectly incarnates Musmeci's architectural theories. The structure cost about 920,000,000 Italian liras (equivalent to €4,000,000 in 2016).

The structure's uniqueness is due to its construction: it is made of only one membrane of reinforced concrete (about {{Convert|30|cm|ft|0|abbr=on}} thick) molded to form four contiguous arches.{{cite journal|author=Carmela Petrizzi|title=Sergio Musmeci a Potenza: il ponte e la città|journal=Basilicata Regione Notizie|pages=17–24|url=http://consiglio.basilicata.it/consiglioinforma/files/docs/10/50/45/DOCUMENT_FILE_105045.pdf|language=it|access-date=2016-08-26|archive-url=https://web.archive.org/web/20150402093335/http://consiglio.basilicata.it/consiglioinforma/files/docs/10/50/45/DOCUMENT_FILE_105045.pdf|archive-date=2015-04-02|url-status=dead}} The concrete sheet is shaped into a “finger-like” structure, which supports the whole bridge, and it is also used as a pedestrian walkway. The unique structure of the bridge has been the subject of several studies and discussions on its structure and form. {{cite journal|author=Marmo, Francesco and Demartino, Cristoforo and Candela, Gabriele and Sulpizio, Concetta and Briseghella, Bruno and Spagnuolo, Roberto and Xiao, Yan and Vanzi, Ivo and Rosati, Luciano|title=On the form of the Musmeci's bridge over the Basento river|journal=Engineering Structures|year=2019|volume=191|pages=658–673|doi=10.1016/j.engstruct.2019.04.069|s2cid=164766610|url=https://www.sciencedirect.com/science/article/pii/S0141029618339786|language=en|url-access=subscription}}

The bridge was built without using prefabricated elements. Edilstrade Forlì-Castrocaro company constructed the bridge.

Plans and drawings of the bridge are collected in the “Musmeci Sergio and Zanini Zenaide archive” which in 1997 was declared of great historical interest by the archival superintendents of Lazio. Then in 2003, it was referred by the Ministry of Heritage and Culture as an example of architecture from the 20th century in the MAXXI (The National Museum of the 21st Century Arts, Rome).{{cite web|title=Collezioni del XX secolo - Musmeci Sergio e Zanini Zenaide|website=Fondazione MAXXI|url=http://maxxisearch.fondazionemaxxi.it/maxxi/collezionixx/XX/fondo/IT-MAXXI-AR0001-0000453#n|language=it|access-date=2015-03-11|url-status=dead|archive-url=https://web.archive.org/web/20151118171704/http://maxxisearch.fondazionemaxxi.it/maxxi/collezionixx/XX/fondo/IT-MAXXI-AR0001-0000453#n|archive-date=2015-11-18}} In 2003, the bridge was declared a “monument of cultural interest” by the Ministry of Heritage and Culture.{{cite web|title=Il ponte e la città.
