Construction site chaos on the A57: danger of traffic jams in Cologne until September!
An extensive construction site has been underway on the A57 near Cologne since July 16, 2025, which will result in numerous traffic restrictions until September 11, 2025. The construction work, which primarily affects the Ehrenfeld and Chorweiler areas, could have a significant impact on commuting. The work began on July 16th at 10:00 p.m. and will last until July 26th at 5:00 a.m. During this time the traffic situation will be heavily impacted and extensive traffic jams are to be expected [news.de](https://www.news.de/auto/858751996/verkehrsmelde-nw-koeln-zur-verkehrsstoerung-wegen-sperrung-baustelle-von-1 6-07-2025-to-11-09-2025-restrictions-in-traffic-north-rhine-westphalia-danger of traffic jams-in-ehrenfeld-chorweiler-on-a57-a1/1/) reported.
The maximum passage width during the construction phase is 3.25 meters. This could be particularly problematic for trucks and larger vehicles, which may need to consider alternative routes. In addition to the A57, there are also numerous construction sites active on the A1, which vary in time and region. Work is planned between the Cologne-Nord motorway junction and the Cologne-Niehl junction, which will also lead to an increased risk of traffic jams.

Current traffic jams and traffic disruptions
Current reports about the traffic situation show that several traffic jams were already caused on the A57 between Krefeld and Cologne on July 18th. An example is a 2 kilometer long traffic jam between Cologne-Chorweiler and the Cologne-Nord junction, which is due to the construction work. This type of traffic stop is not new, as similar situations have occurred repeatedly in the past. In addition, the traffic load in this area is constantly high, which makes the effectiveness of the construction site work important in order to achieve long-term improvement.
Travelers should always keep an eye on current traffic reports to avoid traffic jams and delays. Information about this can be found at stau.info. Sometimes it can be helpful to consider alternative routes to get to your desired destinations on time. Everyone should have a good knack for choosing the best time to drive and perhaps also consider public transport.
