Construction work on the A45: traffic disruption until August 17, 2025!

There are currently several construction sites on the A45 near Siegen, North Rhine-Westphalia, which can have a major impact on traffic. Since August 9, 2025 at 9:00 p.m. and until August 17, 2025 at 9:00 p.m., there will be traffic restrictions in the direction of Giessen, specifically between the Siegen (21) exit and In der Hubach. The construction site is 1.45 km long and the maximum permitted speed is 100 km/h. The roadway width for heavy goods transport is also limited to 6.50 m.

These measures are not an isolated phenomenon on the A45, as work is also being done on the transport infrastructure in other places. Extensive bridge work between Dortmund and Hagen is planned in the coming years, which will last until 2032. Industry experts speak of an extensive construction site landscape that can significantly hinder traffic over a longer period of time. Announcements on verkehrslage.de confirm that the bridge work also affects the roadways in both directions. The sections between the Brunsbecke rest area and the Kattenohl valley bridge and between the Kattenohl valley bridge and Hagen-Süd are particularly affected.

Construction works and their types

The construction sites on the highways are categorized into different types. As explained on strassen.nrw.de, in addition to day construction sites that are only set up for a short period of time, there are also night construction sites and permanent construction sites. The current work on the A45 is expected to be permanent construction sites that will last for a longer period of time and could potentially influence future transport projects.

Road users in particular should prepare for longer journey times in the coming weeks. With the growing volume of traffic and the numerous construction sites, patience is also required. Anyone who regularly uses the A45 can benefit from the official traffic pages and current reports in order to be able to better navigate through the chaos of construction sites.

So stay alert and plan your trips accordingly to avoid traffic jams and delays!
