A temporary construction site has been set up alongside the basin to fabricate the gate housing structures to be positioned on the sea bed (Malamocco and Lido San Nicolò barriers, seven housing structures and two for the abutment connections for each barrier have been built).
In April 2014, the lock for the transit of large ships becomes operative to avoid interference with port activities when the gates are in operation.
Positioning of the gate housing structures for the Malamocco barrier was completed in October 2014.
The seabed in the area where the 19 gates will be installed has been reinforced.
Outside the inlet, a  long curved breakwater designed to attenuate tidal currents and define a basin of calm water to protect the lock has been completed.
