Munich is getting a new long-term construction site. In addition to the Hackerbrücke, which is also scheduled for a three-year renovation starting in 2027, work is now set to begin on the Landshuter-Allee Tunnel. Further postponement of the construction work is no longer possible; the infrastructure is already too dilapidated. Drivers should expect these restrictions over the next three years.
Complete closures and detours

The Landshuter-Allee Tunnel opened in 1979, which is why it no longer meets today’s safety standards. New emergency exits and wider escape routes, as well as new lighting, are to be installed, and the video surveillance and monitoring systems will also be upgraded. In addition, the ceilings and walls will be renovated to ensure greater structural stability. Since December of last year, 7.5-metric-ton vehicles have been prohibited from traveling through the tunnel, and starting in early 2026, 3.5-metric-ton vehicles will also be banned .
Construction work will initially begin in the summer of 2027 in the western tunnel tube, which will require full nighttime closures. During the day, however, traffic will flow as normal. Later, closures will take place in one direction at a time, before work moves to the eastern tunnel tube starting in 2028. This tube will be completely closed, and traffic will be rerouted to the western tunnel. The renovation is scheduled to be completed in 2030.
No extension of the Landshuter-Allee Tunnel

The city estimates that the renovation of the Landshuter-Allee Tunnel will cost 60 million euros, for which it will have to take on new debt. In addition, 13 trees will be removed for the construction work, and 15 new ones will be planted as replacements. Had a noise barrier been chosen, however, a total of 70 trees would have been removed. Instead, the city is relying on low-noise asphalt, which is intended to reduce noise pollution.
The city has now decided against extending the tunnel. Originally, the idea was to build tunnels under additional sections of Landshuter Allee and Arnulfstraße. This would have made sense, particularly in light of the demolition of the Donnersberger Bridge, as a way to save costs. However, these plans have been scrapped, so the project will focus solely on renovating the existing tunnel.
