The U2 station Neubaugasse will become one of the busiest interchange stations in the Vienna underground network, with passengers changing between the existing line U3 running along under the Mariahilfer Straße and the new line U2 crossing the Mariahilfer Straße. The Mariahilfer Straße, one of the best known shopping streets in Vienna with shopping centres and high numbers of passers‐by in the middle of a densely built‐up residential area, and its side streets have been redesigned in the last few years with the aim of traffic calming and creating new public spaces. The building of an underground railway station in such surroundings thus poses a great challenge. Extensive soil investigations, house strengthening measures and utility diversions were carried out in advance. The shafts were constructed top‐down in restricted space conditions. Due to the scarcity of available site facilities areas, deliveries to the site are only possible “just‐in‐time”. Access for local inhabitants and delivery traffic to the side streets, and also for emergency services, has to be maintained during the construction period.
