Construction site alarm: A4 Cologne affected by traffic chaos today!

Today's date, June 12, 2025, will bring with it some traffic disruptions in Cologne and the surrounding area. The road construction work on the A4 between the Cologne-West intersection and Cologne-Klettenberg, which is currently ongoing between 8 a.m. and 6 p.m., is already causing delays in the region. The construction site leads to one-sided traffic disruptions that could affect not only residents but also commuters and travelers. According to news.de, maintenance work is the reason for these measures.

Overall, the traffic situation in and around Cologne could worsen further. In addition, traffic on the A3 towards Oberhausen is backed up, where a 4-kilometer-long traffic jam was reported between Cologne-Mülheim and the Leverkusen junction. A similar picture emerges on other motorways in North Rhine-Westphalia. Stau.info reports further traffic jams, especially on the A59 between Lind and Wahn (2 km) and on the A46 between Erkrath and Kreuz Hilden.

Comprehensive construction site location

The current construction situation is particularly important on the A4. In addition to the work mentioned on the line near Cologne, extensive bridge work is also underway between the Cologne-South junction and Cologne-Klettenberg. These are expected to last until March 31, 2027, which could result in additional restrictions. The traffic situation portal also lists other relevant construction sites, such as the one between the Molbach valley bridge and the Wiehl valley bridge, which is expected to hinder traffic until December 1, 2034.

With a view to the A4, there are several construction sites that extend over a long period of time. Lanes have been narrowed and overall there are short-term restrictions that can significantly lengthen the journey. Drivers are advised to find out about alternative routes in good time or to keep an eye on traffic reports.

Continued traffic congestion

The current traffic situation in Cologne is further exacerbated by various diversions and construction sites on other motorways. The traffic news reports about traffic jams on the following routes:

• A40: 6 km Stau zwischen Dreieck Bochum-West und Essen-Frillendorf
• A57: 1 km Stau zwischen Raststätte Nievenheim West und Köln-Worringen
• A1: 3 km Stau zwischen Kreuz Köln-Nord und Köln-Niehl

Drivers in the region should prepare for a nerve-wracking day and better plan some time to avoid unpleasant surprises. The construction sites and traffic jams show once again how dynamic and challenging the traffic situation in North Rhine-Westphalia can be.
