Construction sites and closures in Schleswig-Holstein: Stay informed!

Today, June 18, 2025, there are numerous construction sites and traffic closures in Schleswig-Holstein that shape the streetscape and influence the mobility of citizens. kn-online.de provides information about the current circumstances with daily updates.

With a total length of 9,874.557 kilometers, the road network in Schleswig-Holstein is extensive. The overview includes traffic routes such as motorways, federal highways, country roads and district roads. The current construction sites are particularly important, affecting traffic on these roads through temporary closures.

Current construction sites on the highways

The A1 motorway is currently severely affected: a full closure will come into force between Ahrensburg and Bargteheide from June 20th to 22nd due to a new bridge being built. There will also be a closure at the Bargteheide motorway junction from June 20th to 22nd. But construction sites are also active outside of this time: a traffic realignment due to construction work will run between Eutin and Scharbeutz until the end of 2025.

On the A21, road users expect the Klein Barkau Ost junction to be closed, which will last until August 2025. The area from Leezen to Bad Oldesloe-Nord will also be affected by road renewal on both sides until December 2026.

Federal and state roads affected

The B75 federal highway will be renovated by September 5, 2025. In addition, the B206 roadway between Bad Segeberg and Rotenhahn will be resurfaced until June 27th. The B432 will also be closed for a full closure near Ahrensbök until July 11, 2025. The construction of a new bridge 506 over the A7 is planned for the L49 and should be completed by September 1, 2025.

There are also full closures on the state roads due to new bridge construction and renovation work, including the L83 near Dreggers until December 18, 2025. The K roads are also affected, such as the K12, which will remain closed until the beginning of October 2026.

Safety and disruptive factors on the roads

In addition to construction sites, it is always important to pay attention to road safety. There are currently no specific reports regarding types of hazards or unusual risks, but drivers should always exercise caution, especially in poor visibility conditions or obstacles on the road that can lead to accidents. In this context, mobile speed cameras should also be mentioned, which are used to monitor speed when stationary systems are less effective.

It is advisable for all road users to regularly inform themselves about the current status of the construction sites and traffic situation. Thanks to daily reports from verkehrslage.de, you can always stay up to date and plan diversions in good time.

So stay careful and use alternative routes wherever possible to make the necessary journeys safely and without wasting much time!
