Traffic chaos in Schleswig-Holstein: construction sites are overwhelming drivers!
In Schleswig-Holstein, drivers are currently faced with a large number of construction sites and closures that have a significant impact on the traffic situation.

The current construction work is announced daily and affects particularly busy routes.
The A1 motorway is currently severely affected by traffic realignments and construction work between Eutin and Scharbeutz, which will last until the end of the year. There is also a two-lane traffic routing in the area of the Bargteheide motorway junction, which will remain in force until December 2025. The renovation of the road between Sereetz and Pansdorf is also a longer process that should be completed by the end of the year.
Current closures and diversions
On the A7, the Flensburg/Harrislee junction northbound will be closed until September 12, 2025. Exits there will not be accessible, especially during the nights of August 27th to 29th, 2025. In addition, there will be a closure between the Owschlag and Schleswig/Schuby junctions from September 1st to October 23rd, 2025.

The B75 is also being renovated between Stubbendorf and Hamberge, which will last until September 5, 2025.
In addition to the large road projects, over 40 smaller construction projects are underway in the country, such as NDR points out. For many of these projects, the holiday season is used to coordinate weather-dependent work and routes to school and to cause as few disruptions as possible. The construction of the new Geesthacht bypass on the B5 is one of the long-term measures that are already planned for the future.
Investments for the future
