Brücke Brunsbecke: Traffic in danger - now emergency measures work!

The dilapidated Talbrücke Brunsbecke in Hagen is a significant challenge for the flow of traffic on the A45 motorway. This bridge between the Hagen-Süd and Lüdenscheid-Nord junctions is currently in operation, although it has been intended for a new building since 2019. A dispute between the clients and adversely led to the shutdown of the construction site, which significantly delayed the plans. Autobahn GmbH has taken various measures since 2021 to ensure the safety and usability of the bridge, including distance bids for trucks, road waving and speed limits.

A bridge test from 2022 showed an assessment of 3.0, which is not considered sufficient. During the examination, 190 defects were found, which refer to various elements of the bridge, such as sliding surface, substructure and main carrier. In addition, an annual special test was ordered to regularly check the condition of the bridge. This often leads to temporary full closures that also affect the flow of traffic. The Talbrücke Rahmede in Lüdenscheid had also had similar consequences for traffic in the past, so that the Brunsbecke bridge benefits from reduced traffic quantities.

The current state of the bridge

As part of an object -related damage analysis, which was already carried out in the summer of 2022, a laser scan was used to capture the exact damage. The results led to the measures that have already been mentioned. The condition of the bridge, which is described as worrying, is particularly alarming. With at least ten points that require special attention, the bridge is permanently monitored to control its condition.

In 2024, extensive reinforcement work began, which have now been completed. In addition, further work on the South Bezel Lager was successfully completed in spring 2025. However, the repair of a transition construction is still pending. The new construction of the bridge is still on the agenda, but should only be implemented completely after a first sub -building has been built. The old bridge is only torn down after completion.

outlook for the future

In addition, acceleration measures were provided for the new building, but no specific schedules for the tender and completion are currently known. A afternotation on the load -bearing capacity and future useful life of the bridge is still pending. This decision has an immediate effect on the remaining years in which the bridge must be used to avoid a complete blocking of the A45.

The Talbrücke Brunsbecke can only be used thanks to the corrosion protection measures that have improved over the years that have improved the condition. For experts in the area of ​​sustainable construction and maintenance management, such as Drees & Sommer, the focus is on the reliable detection of damage and the development of a well-founded maintenance strategy. This not only supports the current state of the bridge, but also aims to prevent future problems while a minimized CO2 footprint is sought at the same time.
