Southeast tangent: hours-long traffic jams due to construction work at the Prater!
On Sunday, October 19, 2025, construction work on the Südost Tangente (A23) in the area of the Prater junction in the direction of Kagran led to significant traffic disruptions. Drivers reported delays of up to an hour and a half because only one lane in the direction of Kagran was passable. The traffic jam stretched from the Prater junction to Inzersdorf and also had an impact on other traffic routes.
There were also delays on the East Motorway (A4) from Schwechat. Drivers also experienced significant disruptions on the through routes such as Landstraßer Belt, Landstraßer Hauptstraße, Erdberger Lände and Erdbergstraße. These current issues highlight the challenges facing transportation infrastructure.
Impact on transport infrastructure
Again PTV Group highlights, a powerful, sustainable and efficient transport infrastructure is crucial for modern economies. Such infrastructures not only improve transport efficiency, but also help address congestion and space problems in urban areas. In the long term, around two thirds of the world's population is expected to live in cities by 2050, further increasing the urgency of a functioning urban transport infrastructure.
The challenges resulting from these current traffic problems are part of a larger trend that highlights the need for intelligently planned transport infrastructure. Accident prevention measures and regular maintenance are necessary to ensure road safety and minimize the associated financial damage.
Traffic strategies and future planning
In addition, traffic planning tools play a crucial role in analyzing existing problems and developing new strategies to support efficient traffic management. According to the ÖAMTC Such long-term planning is essential in order to meet the population's future demands on transport infrastructure.
The current situation on Vienna's streets highlights the need for infrastructure adjustments to take demographic and economic changes into account. This is the only way the transport infrastructure can meet growing demands in the long term and improve the quality of life in urban areas.
