The second TBM reaches the Tricolore station in Milan


On 13.02.2018 the second TBM, launched from Dateo Station on  05.01.2018,  has completed the last underground section from Linate airport to Tricolore Place on the East section of M4 line at Milan.

More than 5 km have been driven with the installation of over 7000 concrete rings for the lining of both the tubes. Which means 40% has been completed for the M4 line.

Next summer two TBMs will begin to drive the west section from San Cristoforo to Solari station. Click here for a video, here and it/16 for tunnelbuilder archive. Visit  http://www.metro4milano.it. 07/18.
