Vienna – As part of the U2xU5 subway expansion, preparatory work is currently taking place for the second construction phase, in which, among other things, the U2 will be extended to Wienerberg. On behalf of Wiener Linien, the City of Vienna – bridge construction and foundation engineering – will be examining the subsoil of the approximately 2.2 km long route over the next few months. The Gußriegelstrasse and Wienerberg stations as well as the Wienerberg operating facility are to be built on this, it said in a press release on Monday.
