Some cruise ships will start to be re-routed away from the historic centre of Venice from next month.
The decision was announced by the Italian government on Wednesday.
It came after five passengers were injured in June when MSC Opera collided with a Uniworld river vessel before crashing into the quayside of the Giudecca Canal.
Italian transport minister Danilo Toninelli said that a number of cruise ships would dock at Fusina and Lombardia terminals away from the centre of Venice, but still inside the city’s lagoon, as a short-term solution.

A third of cruise ships will be re-routed next year.
Ships would be found new berths at a terminal agreed by public consultation in the longer term.
Venues under consideration are Chioggia, at the mouth of the lagoon, and Lido San Nicolo, a ferry terminal on the Adriatic side.
Venice’s mayor, Luigi Brugnaro, has promised to tackle tourism and a €3 tourist tax is due to be enforced from September.
