Scolmatore dell'Arno

As a consequence of the Arno flood of 1949, it was decided to start the construction of Scolmatore dell'Arno in 1954 at a cost of more than 10 billion lire of the time.

The work was not completed in time for the disastrous flood of 1966 that, in addition to Florence, caused enormous damages in Pontedera and Pisa.

A minor tributary is the River Zannone that converges 19.5 kilometers (12.1 mi) from the mouth, just downstream the aforementioned bend of the channel.

The navigability is developed to promote the connection between the dock in the port of Livorno and commercial activities at Guasticce and Vicarello, upstream at a distance of 13 kilometers (8.1 mi).

The project also includes the raising of the deck of the bridge of the Aurelia road (by Stagno) and the construction of docks for loading and unloading of goods at Guasticce and Vicarello.
