Milano city government force the suspension of many public construction in the city. Because of coronavirus emergency. Construction suspended in total 167 construction sites in the city and the environs. Work continue only in 24 projects.

The work on the future M4 is also suspended. Two Tunnel Boring Machines stopped since 8 March. Two TBM stopped at the Vettabbia artifact (between Piazza Vetra and via Santa Sofia) and the De Amicis station. Workers sent hoe for quarantine.

Commissioner for public works Marco Granelli tells Corriere Della Sera, one of the biggest newspapers in Italy, "In the first week the works proceeded at a reduced pace, with a capacity of 30 percent less than in the previous months; but with the ordinance of March 22, everything was blocked" also says. At this moment, just over one hundred people (for 55 construction sites) remain active for surveillance and custody services, 40 of which are housed in the base camp accommodation.

This makes the project completion dates hang in limbo. Nobody knos when the restrictions will end.
