Repair work on the Wiedbachtal bridge
In order to improve durability and stability as well as to guarantee safety, our specialist department for structural maintenance was commissioned by the federal motorway company Autobahn GmbH to repair the Wiedbachtal bridge.
As part of the bridge repair work, we will be replacing the two transition structures of the Wiedbachtal bridge as well as the mastic asphalt surface. The existing roller shutter on the Frankfurt abutment will be removed and replaced with a new swivel beam expansion joint from Maurer SE. As the new transition structure is to be installed without a construction site joint, i.e. in one piece, so-called MMBS slabs will have to be used for the removal and installation for the duration of the replacement. In order to minimise the risk of traffic jams on the busy A3 motorway, the MMBS slabs will be folded up and the work will be carried out at night so that the motorway can be used without restriction during the day.
The mastic asphalt surface will be laid on one side of the structure and in the foreland areas.
The contract value is around €1.4 million net. Construction work began in July 2024 and is expected to be completed in January 2025.
