A42 complete closure in Herne: traffic remains on detours until Monday!
The traffic lights in Herne are currently red: From Friday, August 15, 2025, at 9 p.m., the A42 will be completely closed in both directions on an important section between Herne-Crange and Herne-Baukau. This closure will last until Monday, August 18, 2025 at 5 a.m. The reason for this measure is renovation work to improve traffic routing for the new Baukau tunnel, which is planned as a crucial infrastructure measure. As Radiobochum reports, the demolition and new construction of the northern bridges in the Herne intersection are pending, which will temporarily lead to significant disruption.
Particularly important for all road users: The diversions for traffic have already been determined. Anyone traveling towards Duisburg should use the A2, while drivers heading to Dortmund should take the A2 to the A40 and then on to the A45. So, it's time to plan properly - especially for the upcoming weekend! After the closure, connections from the A43 from the direction of Münster to the A42 will also be closed until midday on Monday (August 18th).
Important traffic information
Here is an overview of the most important information about closures and diversions:
- Zeitraum der Sperrung: 15. August 2025, 21 Uhr bis 18. August 2025, 5 Uhr
- Betroffener Abschnitt: A42 zwischen Herne-Crange und Herne-Baukau
- Umleitungen:
- Richtung Duisburg: über A2
- Richtung Dortmund: über A2, A40 und A45
These renovations are necessary to make traffic flows safer and more efficient. The Baukau Tunnel will be connected to the A42 and will relieve pressure on the existing transport network. It is obvious that long-term investments are being made in the infrastructure here, which should also bring benefits for the residents.
Technological developments in focus
While construction work progresses on the highway, there is also news in the world of technology. An example of this is the Samsung Galaxy A42, a smartphone that is very popular in the USA. Although the device is not directly related to the traffic situation at this point, it shows how important advanced technologies have become in our everyday lives. According to Samsung, the Galaxy A42 provides users with modern convenience while paying particular attention to data protection and collected user data.
When dealing with technology, whether in transport or using new devices, it is always advisable to be well informed and act accordingly. This also applies to investors who want to hedge their portfolio, as demonstrated by the investment strategies described on Schwab. For example, if you are concerned about your finances, hedging could be a way to protect yourself against potential losses. It's a good time to think about your own situation and the changes that are coming.
We will continue to monitor developments in Herne and the impact of the construction site on traffic. So stay tuned and plan your trips well!
