As designed, the new Roma Tiburtina takes the form of a large bridge spanning across the railway lines and connecting between the Nomentano and Pietralata districts. It is an enclosed glazed parallelepiped structure, with a length of 240 metres, a width of 50 metres, and suspended 9 metres above ground level. The interior space is divided into eight separate rooms suspended from the roof. The suspension of the main structure offers several advantages, including a greater level of isolation from the noise and vibration generated by the passage of trains beneath it. The ground level platforms are connected to the suspended rooms above via an assortment of 29 escalators and 52 elevators.
