A large fire at a waste disposal facility in Vienna-Donaustadt has forced the closure of the Südosttangente highway. The section between Kaisermühlen and the Stadlauer Tunnel will be shut down until at least Sunday. Authorities cite an acute danger of the building collapsing as the primary reason for the extended closure. The fire caused significant damage to the facility, compromising its structural integrity. Traffic is being diverted, leading to substantial congestion in the area. Motorists are advised to avoid the area and seek alternative routes. Emergency services are continuing to monitor the situation and assess the extent of the damage.
