Current information on construction sites and road closures in Schleswig-Holstein on June 29, 2025. Avoid traffic disruptions!
Construction site alarm in Schleswig-Holstein: The road remains closed here!
A look at the streets in Schleswig-Holstein shows that the number of construction sites remains high. As of June 29, 2025, several transportation projects are active that affect both highways and federal highways. The total length of the road network in Schleswig-Holstein is an impressive 9,874.557 kilometers, with the motorway network covering approximately 545.108 kilometers. This includes the A1, which continues to be affected by diversions and construction work between Eutin and Scharbeutz, which will last until the end of 2025. The traffic routing in the area of the Bargteheide motorway junction will also have two lanes until December 2025, so dry planning is required.
The A21 also has its construction sites, including the Klein Barkau Ost junction in the direction of Kiel that will be closed until August 2025. The work to renew the road between Leezen and Bad Oldesloe-Nord will last until December 2026. The situation is no different on the A23: There are various closures between Pinneberg-Nord and Halstenbek/Rellingen until the end of July 2025, while traffic towards Hamburg will be blocked at the Heide-West entrance and exit until July 25, 2025. These construction measures are necessary to maintain and improve the region's infrastructure, as kn-online.de reports.
Various construction sites and their effects
In addition to the motorway construction sites, there are also innovations on the federal highways. The B75 will be resurfaced by September 5, 2025, while the B404 is also affected by the closure of the Klein Barkau Ost junction. The B432 will be completely closed near Ahrensbök until July 11, 2025. The state roads are also heavily used: The L49 provides for the construction of the new bridge 506 over the A7, which should be completed by September 1, 2025.
The descriptions of the construction sites on the district roads should also not be neglected. For example, there is a bridge renovation on the K1 between Wensin and Steenkrütz, which will last until the end of October 2025. Such measures are important to ensure the safety of road users and to avoid traffic jams so that the volume of traffic does not build up unnecessarily, as can also be found in the construction site information from kfz.net.
Traffic conditions and safety
The current construction sites not only lead to traffic disruptions, but also pose challenges in terms of traffic safety. The accident statistics for Schleswig-Holstein show that errors when turning and inappropriate speed are common causes of accidents. In addition, young drivers and drivers over 65 years of age in particular have an above-average number of accidents. Motorways such as the A215 are also affected by this, with a five-fold increase in the number of accidents, which further underlines the need for construction work.
Predictive driving is particularly important at the moment, as construction sites often create obstacles and restrictions on the road. The traffic situation signals special caution in these places and appeals to vehicle drivers to show patience and observe the respective speed limits.
Overall, the situation on the roads of Schleswig-Holstein is dynamic and requires good skills from all road users in order to get to their destination safely and quickly. Stay patient, keep an eye out for current information and plan your routes ahead!
