Truck fire in Walldorfer Kreuz: A5 and A6 closed for hours!
On Friday, June 20, 2025, there was a serious incident at Walldorfer Kreuz, which led to significant traffic disruptions on several sections of the motorway. A truck semi-trailer burned on the A5, the bridge over the A6, causing massive smoke. The A6 in the direction of Heilbronn was then completely closed, as stimme.de reports.
The fire brigade was quickly on site and was able to put out the fire. However, the extinguishing work is still in progress. Parts of the burning semi-trailer fell from the bridge onto the A6, further increasing the risks and complexity of the situation. At the same time, the A5 also had to be closed. According to police, the closures will last until at least 3:30 p.m.
Traffic disruptions and diversions
The traffic situation at Walldorfer Kreuz is dramatic. According to the SWR traffic jam report, a six-kilometer traffic jam has formed between the Hockenheim triangle and the Walldorf intersection. Motorists are urged to avoid the area as the disruption is significant. The A5 is completely closed in both directions due to the heavy smoke, which makes the situation even more difficult for commuters and travelers, as swr.de notes.
The truck was on the bridge in the direction of Heidelberg, and the cause of the fire is still unclear. At this time there is no information about possible injuries, but the bridge was affected by the fire. It is uncertain whether it is still safe to drive following the cause of the fire, which could lead to a possible longer closure, particularly if the asphalt on the A5 is damaged.
The road traffic authorities and the fire brigade are still on duty to completely eliminate the consequences of the incident and to ease the traffic situation. Further developments are expected, which could potentially lead to permanent traffic restrictions if more damage is found.
