Construction of MOSE at the inlets necessitates complex logistical organisation. These are located in a highly delicate environmental context so as to avoid interfering with the surrounding area as far as possible. The sites have been set up on temporary areas of water in order to limit occupation of the land adjacent to the inlets and reduce as far as possible the effect on activities taking place there. Materials (for example, site supplies) and machines are also moved via sea to avoid overloading the road system along the coast. Since the sites opened, all work has been carried out without interrupting transit through the inlet channels.
Below is a description of the work underway and already completed at each inlet, listed in order from North to South.
