There are different opportunities: a railway station for international, regional and high-speed lines and the creation of a great urban square, a monumental high-ground boulevard connecting the districts. Above the railway tracks, the large pedestrian way appears as a bridge-station or a large covered urban square, an intermodal social and urban exchange point.
The reinvention of the great nineteenth-century glazed gallery is clearly visible in this process of technological and spatial innovation. A great luminous bar, a 60 meters wide and 350 meters long glass volume suspended on the tracks and supported by the two urban accesses Pietralata and Nomentano, connecting the new station with squares, traffic fluxes and the different users in the surrounding districts.
The station is built on a preexisting metal platform along the urban axes and lies on a series of pillars based on the platforms underneath. These pillars support both the whole boulevard and the station at 9 meters height from platforms.
Due to the sensitive oscillations that the bridge deck constantly receives, the structure is designed as a large coverage or a steel framework roof. A monumental shelter where translucent volumes hang onto and which hold the main station services: VIP lounges, internet offices, directional offices and restaurants. Evocatively framing the shape of the hanging volumes, the glazed facade lies on the preexisting platform and hangs on the metallic roof.
The choice of this hanging structural typology maximizes the role of structural spans while contrasting the potential critical issues of wind and railway vibrations (the prize Eurosolar 2002 Italian edition has been awarded to the project).
