A new public public construction site in Vienna is starting almost on time at the beginning of astronomical autumn, and again the U4, which has been plagued in this regard, has been affected by construction work recently. From Monday morning, September 22nd, the stop at the U4 stop Landstrasse (Vienna Mitte) in the direction of Heiligenstadt will not be met for six weeks, up to and including November 2. The trains drive through here. In order to continue to reach the U4 station, passengers can continue to drive a station to Schwedenplatz and then take a train in the opposite direction. According to the Viennese lines, the blocked platform receives a new floor covering, the asphalt is replaced by a light granite floor. For people with visual impairment, the “tactile floor information system” is modernized.
