Green light for blue line
Work has started on the next line to be added to Milan’s metro network with the opening of excavation sites for the stretch between Tricolore and Argonne.
Once completed, the blue-coded M4 line will connect the city airport at Linate in the east with S. Cristoforo in the south-west, passing through the centre in Piazza S. Babila, where it will connect with the red M1 line, and S. Ambrogio with the green M2 line. Connections to the surface rail system will be made in S. Cristoforo, Dateo and Forlanini stations.
The 15.2 km of rails will boast 21 stations, and are expected to carry 86 million passengers per year, thus reducing surface travel by car by some 14 million trips. Ultra-modern, driverless trains will be totally automated, and platforms will be screened off from the rails until the train stops in the station. Peak speed will be 80 kmh, carrying up to 600 passengers on each of the 40 convoys deployed at rush-hour times.
The new line should be completed by 2022, although certain stretches should be operative before that date.
For the moment, work is starting around the Dateo station with the cordoning off of the excavation area and the redirection of road traffic. Only Via Nullo will be closed to all but residents, while other streets may suffer a restiction of width. Lanes will be thinned in Corso Concordia, and reduced to one in each direction in Corso Plebisciti, but traffic will otherwise not be affected.
A dedicated website (link to the left) already offers full details of the new line, and is being constantly updated with useful information, including news about traffic modifications caused by the construction work.
