Construction site chaos on the A1: Leverkusen will be a traffic jam until 2026!
In Cologne and the surrounding area, drivers are faced with significant traffic restrictions due to a large-scale construction site on the A1 motorway. These measures, which began on April 25, 2025, are scheduled to last until March 5, 2026 and could cause numerous traffic jams and delays.

What's going on? Drivers have to prepare for increased traffic volumes, especially in the Leverkusen area. Several sections of the highway are affected here:
- A1, AK Leverkusen (98) – AK Leverkusen-West (99):
- Richtung Dortmund nach Köln
- Länge: 0.35 km
- Max. Geschwindigkeit: 80 km/h
- A1, AS Köln-Niehl (100) – Leverkusener Brücke:
- Richtung Köln nach Dortmund
- Länge: 0.25 km
- A59, Leverkusen:
- Einseitige Baustelle
- Maximale Durchfahrtsbreite: 3.75 m
The entire measures will end on March 5, 2026, with the first phased restrictions lasting until July 30, 2025. Therefore, all road users should be particularly attentive and allow time buffers when driving through this busy area.
Current traffic situation
A look at the current traffic situation shows that the construction site is affecting the entire region. According to the latest reports, some sections of the A1, for example between Wuppertal-Langerfeld and Wuppertal-Nord, are affected. Despite the construction site, there were no significant delays, as stau-a1.de reports.
Current traffic reports from today (June 20, 2025) further clarify the situation. While sections on other routes are recorded without delays, there is a risk of traffic stalling due to the construction sites near Leverkusen. Numerous drivers even report waiting hours on the diversion routes.
Long term perspective
These measures are part of broader expansion projects aimed at improving traffic flow on the A1. With a length of around 750 km, the motorway is the third longest in Germany and runs from Heiligenhafen to Saarbrücken. Strong frequencies and a predicted increase in the number of vehicles by over 80,000 daily over the next ten years illustrate the need for action. verkehrslage.de explains that the measures not only serve to maintain the infrastructure, but are also a response to the growing volume of traffic.
For Cologne and the surrounding area, we can only hope that the construction sites run smoothly and quickly so that traffic can soon flow unhindered again. In the meantime, drivers should adjust their travel times and always keep an eye on information about the current traffic situation.
