Massive traffic disruptions in Cologne: closures starting tonight!
Watch out in Cologne today! From August 26, 2025 at 9:00 p.m. there will be some traffic disruptions, especially on the highways and streets around the cathedral city. These are expected until 5:00 a.m. on August 27, 2025, and motorists should prepare for various closures. Loud news.de Traffic will be severely affected, especially on the A1 between Cologne-Bocklemünd and Cologne-Lövenich. Construction work is taking place here, which will completely close the carriageway.
But that's not all! Construction sites are also expected on Venloer Straße and Aachener Straße in Cologne, which could lead to further traffic jams. Things are likely to be particularly tricky on the A1 towards Euskirchen, where construction sites are also disrupting traffic between the Frechen and Cologne-Bocklemünd junctions. Anyone traveling towards Heerlen or Aachen must be prepared for closed crossings to the A1 at the Köln-West intersection and, if necessary, choose alternative routes.
Detailed traffic disruptions
A comprehensive overview of the closures is also available from WDR, which point out that the Lövenich tunnel will be temporarily closed in both directions due to maintenance work - not just tonight, but also in the coming nights. The motorway in the direction of Dortmund will be affected on the nights of August 27th and 28th and in the direction of Euskirchen on August 28th and 29th. The diversions are marked and should be observed to avoid unpleasant delays.
Construction work in the Lövenich tunnel is necessary to ensure the safety of the journey. The tunnel, which is around 1.5 kilometers long and is embedded in a modern steel and glass construction, is maintained every three months. Since this route passes through busy residential areas, this maintenance also ensures that traffic noise reduction is working.
Redirection strategies and advice
According to that ADAC Due to the numerous construction sites in North Rhine-Westphalia, drivers should keep a close eye on the traffic situation. There were already numerous construction sites, especially at the weekend, which made driving conditions more difficult. It is recommended to use alternative routes such as the A3 and A4 to avoid traffic jams.
Overall, we are facing a challenging traffic situation in Cologne. Drivers should inform themselves in good time, plan alternative routes and allow enough time for their journeys. Stay patient and drive safely!
