The expansion of Budapest's Southern railway connection line has been among the capital's development priorities for years. In addition to enabling a greater transit capacity for freight and passenger traffic, the project also improves the viability of the affected neighborhoods, stations, and buildings, its most significant structures include the multilevel railway link at Ferencváros Train Station, the double arch bridge beneath Közvágóhíd Train Station, and the twin-bridge at the crossing of Bartók Béla Street. These remarkable structures span over 100 m each.
