Construction site chaos in Schleswig-Holstein: Where the traffic is at a standstill!

What is happening in traffic in Schleswig-Holstein? Today, September 18, 2025, inform us KN Online about current construction sites and closures in our state. With a total length of almost 10,000 kilometers, Schleswig-Holstein's road network includes motorways, federal highways and numerous country and district roads. A real thicket to penetrate!

In the next few days, drivers will have to keep an eye on the traffic signs, especially on the A1 motorway. There will be night closures here from September 19th to 26th in order to build a new bridge. The diversions lead via the L89, K106 and L224 to Ahrensburg in the direction of Hamburg and back. Work is also underway on closed lanes and exits between Oldenburg Süd and Gremersdorf until September 26th. Anyone traveling in the Eutin and Scharbeutz region will only discover one lane towards Lübeck until the end of the year, while two lanes lead to Fehmarn.

Details about the construction sites

It gets just as tight on the A7. Passengers between the Owschlag and Schleswig/Schuby junctions have to prepare for restrictions until October 23rd - the roadway here is being renewed. The Owschlag entrance and exit will also remain completely closed until September 22nd. There will also be a complete closure on the A20 between Lübeck and Lübeck-Genin from September 19th to 22nd as the roadway here is being replaced.

The A21 will continue to be resurfaced on both sides until December 2026. Drivers on the A23 must prepare for full closures of the Hohenfelde junction and the Heide-West junction until the end of October.

New challenges keep arising: For example, a closure will be necessary on the B502 between Heikendorf and Schönkirchen until September 21st. The L26 will also not be passable between Klein Waabs and Karlsminde until November 11th.

Current traffic situation

It is important to know: There are currently no reports on types of danger, such as verkehrslage.de determines. However, there is always a certain risk due to the risk of slipping due to slippery surfaces or black ice, which can occur in winter. Drivers also have to expect hindrances caused by obstacles on the road, such as tires or car parts.

Wrong-way drivers who could be driving the wrong way on the roads also pose a risk. So if you want to cruise safely through Schleswig-Holstein, you should keep an eye on all construction sites and detours and take the information on the traffic signs seriously. The goal is to get to your destination safely and without delays!

For commuters seeking advice, there is comprehensive information on how to keep an eye on traffic conditions and choose the best route. This makes getting to work or the next destination a little easier.
