Construction site on the A45: traffic chaos between Schwerte and Dortmund!
From today, December 8, 2025, the road traffic situation in North Rhine-Westphalia will be influenced by a construction site on the A45 between the Westhofener Kreuz and Schwerte-Ergste. This measure, which lasts until December 11, 2025, ensures that the two left lanes in the direction of Dortmund to Hagen are closed, narrowing the roadway to just one lane. Road users must therefore be prepared for possible disruptions and a slow flow of traffic. This [News.de]. The team recommends slowing down your driving behavior to ensure the safety of all road users.
Already on December 7th, there were several traffic jams on the A45, particularly between the Dortmund-West intersection and Dortmund-Hafen, where there was gridlocked traffic for over three kilometers. But other sections of the motorway were also affected, as reported by Stau.info. Several accident scenes have been cleared here and reports of traffic stoppages have been lifted, but the danger remains. The current construction site will certainly make the situation even more complicated in the coming days.
Planned work and traffic information
The construction site on the A45 is active from Monday to Wednesday between 8:00 p.m. and 12:00 a.m. This will further impact traffic, which commuters and travelers should be aware of, especially during the evening hours. Those responsible ask for patience and adapted driving behavior during this period.
The data on traffic volume and the most common causes of traffic jams is not only monitored by regional authorities, but is also part of the comprehensive statistics of the Federal Ministry of Transport and Digital Infrastructure. The annual compendium, known as “Traffic in Numbers” (ViZ), contains relevant information about mobility behavior in Germany and provides insight into investments in infrastructure. This year's surveys already show an increasing trend in traffic volume, which is reflected in the traffic jam and accident statistics. Further information can be found on the BMV website.
With the current construction sites and associated traffic disruptions, it is advisable to plan the time and route in advance to avoid unnecessary delays. Be alert and adhere to speed to ensure your safety on the roads.
