The section U2/7 ‘Donaustadtbrücke’ is a part of the extension of the U2 under-ground line from Schottenring to Aspern.
This part of the U2 - extension starts at high level with the station building ‘Donaustadtbrücke’ consisting of two parallel prestressed reinforced concrete box sections as side platforms and the two train tracks on top of precast concrete slabs embedded between these box sections.
The station bridge crosses over a six lane motorway. The spans of the station bridge are 32.5 m+ 27.5 m+35.0 m+25.0 m (length 120 m) for one box section. The station housing on the bridge was done with a steelwork and glass structure.
The regular route consists of double track bridge sections with spans between 15.0 m and 75.0 m with a total length of 770 m (excluding the station length of 120.0 m).
