The new ALICE Inner Tracking System (ITS), the vertex silicon detector of the experiment, has been developed to cope with an interaction rate of 50 kHz in PbPb collision foreseen after the phase-II upgrade of the LHC at CERN. The new ITS will replace the present one with seven cylindrical layers of ALPIDE, a Monolithic Active Pixel Sensor developed by the ALICE Collaboration. The detector, currently under construction, will be ready by the end of 2019. In this contribution an overview of the status and the expected performances of the new ITS will be shown.
