Landshuter Allee tunnel in Munich to be refurbished and given safety upgrade

The Landshuter Allee tunnel in Munich is to be refurbished and fitted with upgraded safety equipment. The city council's building committee granted project approval for the work at a preliminary session on 15 September 2026. The approved cost is around 60 million euros.

The city's building department is required to carry out the work because the safety equipment in the tunnel, which opened in 1979, no longer meets current standards. Detailed inspections have also found an urgent need for repairs to the structure and its fire protection. The aim is to significantly improve safety in the tunnel.

Planned measures include fitting fire protection panels to the tunnel ceiling, widening the existing emergency walkways and adding extra escape doors in the central wall. Automatic fire detection and monitoring systems will be installed, and the tunnel lighting and escape route signs will be modernised. The existing tunnel operations station will be extended with a new building, to be shared with the city's utility company, Stadtwerke München.

The structure will also undergo a full overhaul. Concrete damage will be repaired, wall cladding replaced and all of the infrastructure brought up to date.

The work will be carried out in four main phases. After preparatory work, such as clearing the construction site, fire protection work will begin in the western bore from summer 2027, initially at night. During the later phases, one bore will be closed at a time, with traffic running in both directions in the other bore. The whole project is expected to be completed by spring 2030.
