text: There will be two rows of gates at the Lido inlet (21 mobile gates for the North barrier Lido-Treporti and 20 mobile gates for the South barrier Lido-San Nicolò).
  To the north of the inlet (Treporti), a small craft harbour consisting of two basins communicating through a lock, will allow small craft and emergency vessels to shelter and transit when the gates are raised. The sea-side basin was temporarily drained and sealed for use as the site to construct the gate housing structures for this barrier. Once the housing structures had been completed, the area was flooded with water to allow the housing structures to be floated out.
  The housing structures for the gates in the north barrier (seven housing structures and two for the abutment connections) were positioned on the seabed. Four of this barrier's gates were installed and manoeuvred for the first time in October 2013; at the end of 2014, the installation of 21 gates was completed and operational for functional testing purposes (the so-called "blank tests").
  At the south of the inlet (San Nicolò), the launch and the positioning of seven housing structures and two for the abutment connections has been completed (the structures have been fabricated on a temporary raised area in the Malamocco inlet and will be taken out to sea by a giant mobile platform which functions as a giant elevator).
  At the centre of the inlet, a new island has been constructed to act as an intermediate structure between the two rows of mobile gates. This island will accommodate the buildings and plant for operating the gates (construction underway).
  Outside the inlet, a  long curved breakwater is almost complete.
