Large locks in the Vienna Transport network: this is what awaits you this summer!

Large locks in the Vienna Transport network: this is what awaits you this summer!

Siebenhirten, Österreich - Summer time is also building time in Vienna: From June 28, 2025, the S-Bahn master route between Floridsdorf and Praterstern will be closed for around two months. A comprehensive rail replacement traffic will be set up by September 1st, which runs under the bus lines SV900 and SV905. This measure is part of a larger plan to modernize and renew the Vienna Transport Network, which is particularly the focus this year, as the ÖAMTC

The S40 is also affected, since the rail replacement traffic is activated during the lock between Klosterneuburg-Weidling and St. Andrä-Wördern from June 29 to September 1, 2025. Trips to the lines R40 and Rex4 are completely out of this period, which means a change for many commuters.

U4 and track work

The U4 is also affected: from June 28 to August 31, 2025, the routes between Schottenring and Friedensbrücke are closed. Here the U4 is only active between Heiligenstadt and Friedensbrücke as well as between Schottenring and Hütteldorf. Good news: Replacement lines such as the tram line E4 and the redirected line D are available, which drives from Nussdorf to Schottenring, such as the confirm.

Background of this extensive work is the age structure of the U4, the tunnel infrastructure of which is now over 120 years old. In order to ensure reliability and safety in traffic, the track and course work are essential. At the same time, the track infrastructure is also modernized on various other lines, including the U6 - which is why the Tscherttegasse station will only be approached in the direction of Siebenhirten by December 2025.

more fights for the place

These extensive conversions are not limited to the subway and the S-Bahn. Also on the ring road there are blocks and diversions for lines 1, 2, 71 and D from June 28 to the end of August 2025. The reason is massive track and switch work that affect these main artery. For many travelers, this means that they have to adjust to a changed traffic situation.

The enormous track work is also continued elsewhere. From July 1st to the end of August, the tracks on the Carinthian Ring, University Ring and Schubertring will be replaced, which will also lead to restrictions on different lines. The following applies to many travelers: bring more patience and switch to alternative means of transport, because the Viennese lines have announced that they will condense the intervals for other lines, such as the U6 and numerous tram lines, near the construction sites.

A look into the future

The modernization and the network expansion of the Viennese lines will continue beyond 2025. From autumn 2025, passengers can look forward to new tram lines 12 and 27, and the extension of line 18 to the stadium is also already in the planning. As the orf , this renewal is part of a large -scale modernization offensive that started in 2024 and is now starting up.

The summer months have some challenges for the Wiener commuters, but with a good hand and the right planning, nothing stands in the way of a stress -free journey.
