The traffic lights at the Boxgraben/Mozart-/Karmeliterstraße junction failed at around three o'clock in the night from Thursday to Friday (November 20/21). The fault was caused by unknown persons forcibly knocking the control unit box off its base. The control unit of the traffic light system and the electrical connection were destroyed in the process. The traffic lights have been out ever since.

There will be tailbacks in all directions. According to current estimates, the traffic lights will be out of action until at least Thursday of next week, November 27. The damage amounts to at least 30,000 euros.

To ensure that the junction is still passable, the city council has closed lanes at the junction on behalf of the traffic authority. As a result, it is no longer possible to turn left from Karmeliterstraße towards the main railway station for the time being. It is also no longer possible to turn left from Boxgraben in the direction of Karmeliterstraße.

The civil engineering work required to repair the cabinet base is scheduled to take place on Tuesday, November 25. The control unit and the new control cabinet are to be installed on Wednesday or Thursday at the latest. The connection by Regionetz is planned for Thursday, so that the traffic light system can probably be put back into operation on Thursday afternoon, November 27.
