Allacher Tunnel: Politicians fear traffic chaos – immediate measures required!
Concerns about the Allacher Tunnel in Munich are increasing. Around 132,000 vehicles use this important transport route every day, which is a central connection in southern Germany for many commuters. There are always bottlenecks, especially at peak times, with up to 10,000 vehicles per hour traveling along the route, which is already prone to traffic jams. Political voices are now calling for quick measures to prevent impending traffic chaos during the planned renovation work from 2028.
The renovation of the Allach Tunnel is expected to last eight years and includes comprehensive repairs to the tunnel walls as well as the installation of new operating technology and drainage systems. During this time, only the hard shoulder will be open to traffic, which could significantly worsen the traffic situation. Political representatives of the CSU and the Free Voters express alarm about the coming challenges and are pushing for measures to alleviate the traffic load in order not to endanger the mobility of commuters.
Political demands and measures
A specific proposal includes the creation of a commuter parking lot near the Feldmoching motorway triangle and the expansion of express bus connections to relieve congestion in the north of Munich. Politicians have also suggested special lanes for buses and carpooling. These should only be used by vehicles that are occupied by at least two people in order to cover the increased need for rides during the renovation work.
An increase in the truck toll on the affected section of the motorway is also being discussed. This is intended to help reduce truck traffic and thus make a further contribution to preventing traffic chaos. Munich city politicians are calling for these measures to be implemented quickly, including the mayor, who described the delays in the S-Bahn Nordring as “completely incomprehensible”.
View of the S-Bahn Nordring
However, the construction of the S-Bahn Nordring, which was intended to help relieve traffic in the north, has been delayed until the 2030s because planners are still missing. This makes the situation around the Allacher Tunnel appear even more urgent, as commuters are hoping for a quick solution. A spokesman for Deutsche Bahn makes it clear that there are no commitments for the Nordring to be put into operation in 2025; the DB expects a start at the beginning of the 2030s. Local politicians are therefore faced with major challenges that must be overcome in the interests of the citizens.
The coming years will bring exciting, challenging times not only for commuters, but also for city politics. When looking for solutions, innovative approaches are required to ensure mobility in Munich even during major construction projects.
