The project included the construction of the Bologna – Conca d’Oro main section, already in operation since June 2012 built by the same group of companies led by Salini Impregilo S.p.A., The project as a whole, going from the Bologna station to the Jonio station, connects the Montesacro neighbourhood in Rome and the entire north-east quadrant with the city centre, Termini railway station, Metro line A, and the southern suburbs of Rome in just over ten minutes, favouring the use of rail transport rather than cars.
The Jonio station, the last to be opened to the public, is the terminal station of the entire section, which comprises four stations, five shafts, 7,200 m of single tunnel track (6.70 m in diameter) and 1,100 m of the double-track tunnel (9.80 m in diameter).
The project has been completed with a series of urban upgrading works, including the green areas of Piazza Annibaliano and Piazza Conca d’Oro, the garden on the roof of the car park and Ionio station, the football field of the parish of the Santissimo Redentore, and the repaving of the main roads of Municipal District no. 3.
The construction of the entire section was made possible by the commitment of the over 300 people employed, including managers, technicians and workers. Over this ten-year period, there were times when they had to work more than a shift a day, ensuring that the construction site was manned seven days a week.
