Construction site chaos in Schleswig-Holstein: Where the roads are now closed!

Today, July 3, 2025, it's that time again: The construction sites and road closures in Schleswig-Holstein are keeping drivers on their toes. The current overview shows that the road network in the northernmost federal state of our country has a total length of9874.557 kilometershas. From motorways to federal highways to country and district roads, everything is included. KN Online has compiled the most important information on a daily basis.

There are some construction sites, particularly on the A1 motorway, which are causing traffic changes. Work continues on the road renewal between Eutin and Scharbeutz, with the aim of completing the work by the end of the year. The traffic routing currently provides for one lane in the direction of Lübeck and two lanes in the direction of Fehmarn. In addition, there will be a two-lane traffic routing in the area of ​​the Bargteheide motorway junction until December 2025, while traffic adjustments are expected between Sereetz and Pansdorf by the end of the year.

Current construction sites and closures

The A21 is also affected: the Klein Barkau Ost junction in the direction of Kiel will remain closed until August 2025. There are also some restrictions on the A23, including full closures between Pinneberg-Nord and Halstenbek/Rellingen until the end of July 2025. The Heide-West entrance and exit towards Hamburg will not be accessible until July 25, 2025.

• A1: Bauarbeiten zwischen Eutin und Scharbeutz bis Ende 2025
• A21: Sperrung der Anschlussstelle Klein Barkau Ost bis August 2025
• A23: Vollsperrungen bis Ende Juli 2025
• B432: Vollsperrung bei Ahrensbök bis 11. Juli 2025

The construction sites are not only found on the motorways. On federal highways such as the B75 and B77, the roadway is being replaced and sections of the route are being closed for maintenance work. Drivers should therefore plan well to avoid delays.

Traffic conditions and safety

There are currently no reports of any particular dangers such as slippery winter conditions or other problems that could affect road safety. Verkehrslage points out that construction sites are temporary works that ensure that the roads remain in good condition. An important aspect is to be aware of possible dangers, such as obstacles on the road or the danger of wrong-way drivers.

Structured traffic management and anticipatory driving help to avoid accidents and ensure that everyone gets to their destination safely. While some road users are annoyed by the construction sites, others may be able to enjoy the well-renovated roadway in the future.

Be it on the highways or in the city, traffic information is important in order to reach your destination safely. Staying informed means driving safely, and that should be the top priority for all road users in Schleswig-Holstein.
