Railway Bridges over Dunav-Tisa-Dunav (DTD) Channel as part of the High-Speed Railway Design Belgrade-Budapest, Section Novi Sad-Subotica-State Border

As part of the design of the Belgrade-Budapest high-speed railway project, the design of the section Novi Sad-Subotica-State border with a length of 108 km was completed. The railway is designed for a maximum speed up to 200 km/h. The route of the Novi Sad - Subotica - State border high-speed railway crosses the Danube-Tisa-Danube canal (DTD) in several places. The most significant bridges over the canal are: 1. The bridge at km 81+644 is a continuous steel truss bridge on three spans of 42.0+56.0+56.0 m. 2. The bridge at km 0+796 is a continuous girder on three spans of 27.6+82.8+27.6 m. The end span sections are box girders, while the middle span is designed as a steel truss. 3. The bridge at km 110+351 is a simply supported beam, steel truss bridge with a span of 63.0 m. 4. The bridge at km 117+151 with a total length of 1463 m is the longest bridge on the alignment. There are a total of 43 piers. Majority of structures are prestressed concrete beams L=31.5 m, box girder section. 8 spans are steel trusses of span L=48.75 m. The designs of all structures were done according to Eurocode, UIC and RIL recommendations. The Design for Building Permit was completed during 2021, the Design for Construction (DFC) [1] in the first half of 2022. The works started in July 2022 and new line opening is expected by the end of 2024.
