Traffic chaos on the A4: massive construction site until 2026!
There's a lot going on on the streets in Cologne at the moment, and that won't change in the coming months. From June 26, 2025, the A4 between the Cologne-Süd motorway junction and the Cologne-Poll exit will be significantly impaired for road users due to necessary bridge repair work. Loud news.de The construction site will last until July 31, 2026.
Increased traffic volumes and potential congestion must be expected during this construction period. The A4 section, which is 2.45 kilometers long, is particularly affected. The maximum passage width for heavy goods transport is limited to 10.50 meters.
Further construction sites and traffic restrictions
The A4 is not the only problem child: other construction sites are currently underway that are affecting the flow of traffic in the region. For example, there is work on the Wiehl viaduct, where the right lane is closed and the road has been narrowed to one lane. This measure will last until December 1, 2034, and the total allowable load is temporarily 44,000 tonnes, as stated on verkehrslage.de reported.
In addition, the bridge on the A4 between the Cologne-Süd intersection and Cologne-Klettenberg will be repaired by March 31, 2027, which will also significantly restrict traffic. A look at the construction sites shows that not only technical challenges have to be overcome, but responsibility for traffic safety also plays a central role.
Traffic management and technology
In these times, when construction sites and traffic breaks often go hand in hand, the topic of traffic management becomes increasingly important. Innovative solutions like these swarco.com described aim to improve traffic flow and safety. Modern systems use, among other things, induction loops to detect vehicles and intelligent traffic management systems (ITS) to minimize traffic jams and improve air quality.
Is there hope for smooth traffic at the end of the row of construction sites? That remains to be seen, but the ongoing work will test the patience of many drivers. A good knack for planning travel times could prove helpful in cleverly avoiding construction sites and avoiding unnecessary delays.
