Construction
The first three stations of the line (Linate-Repetti-Forlanini) was originally planned to be completed in 2015, as part of the works for the Milan Expo. However, delays in planning, financing[7] and construction works forced to postpone the opening, with the first section opening on 26 November 2022[3][8] and the rest of the line expected to open by 2023.[9] The line is 15 km (9.3 mi) long with 21 stations, with its final 13 stops opening on 12 October 2024.[10]
The consortium ATM-Webuild is responsible for the construction works.[11][12]
Of the total estimated cost of about €1.7 billion, the Government of Italy will cover €786 million via a grant, the municipal government of Milan will cover €400 million, and €512 million will be funded by private investors.[11]
