This double-arched bridge spans the Rio torrent, which is the left tributary of the Savio River. It was built on the orders of the Grand Duke of Tuscany Pietro Leopoldo between 1775 and 1780, while previously the Rio torrent had to be dangerously forded. The bridge is an exact replica of the one built a few years earlier over the Savio River, designed by the Grand Duke's engineer, Giovan Battista Bettini. It has recently been restored and is open to traffic.
