Subway line U3/6+7 – Connecting Track Stubentor Station

Project Description

Project description:
Subway line U3:  connecting track U3 to U4: km 0.289 - km 0.949
U3:  km 17.608 – 18.484
Section length: connecting track: 659 m, U3: 876 m
Total track length: 2,411 m
The connecting track links the subway line U3 to the line U4. Parts of the connecting track (under Julius Raab Platz) had already been built before the construction works started. The respective area was built as a single-track tunnel using the New Austrian Tunneling Method. The groundwater level was lowered by wells.
The U3 part of the construction section runs from the Landstraße station to the Stubentor station via two single-track tubes. The Stubentor station consists of two station tubes on different levels. Past the Stubentor station, two single-track tubes continue to the Stephansplatz station. All tunnels were built according to the New Austrian Tunneling Method (NÖT), by using compressed air. The passages of the station were built with the cut-and-cover method with diaphragm walls. Parts of the medieval retaining wall were integrated into the station building.
