Significant disruption awaits road users, as higher traffic volumes and possible traffic jams are expected throughout the entire duration of the work. The entire period of construction work extends until November 26, 2025, with some closures coming into force today. My Cologne reports that ...
Additional construction sites
However, the current work is only the beginning: Further construction work on the A4 in Cologne is already planned for the end of November, which will last from Friday, November 28th, 2025, 10:00 p.m. to Monday, December 1st, 2025, 5:00 a.m. These affect, among other things, the areas of Radenkirchen and Lindenthal and only make traffic in these areas easier to a limited extent. A one-way bypass system is already in place here.
The traffic management centers strongly recommend that you plan routes in advance and regularly inform yourself about the current traffic situation. Anyone who relies on the roads in the region should prepare well, as many diversions have been set up. ADAC NRW also provides an overview of further closures and diversions.
In summary: Drivers in and around Cologne should prepare for inconvenience in the coming weeks. A good hand when driving and observing the current traffic restrictions are now more important than ever.
