Emergency repair of Weser bridge (A1)

In October 2020 the J.H.K. Anlagenbau und Industrieservice Bremerhaven und Ahlhorn acquired an infrastructure project from the DEGES (Deutsche Einheit Fernstraßenplanungs- und –bau GmbH) of the Weser bridge on the Autobahn A1.

 

After a short-term inspection on site, the works started only five days later with all necessary equipment. Several repairs of steel construction parts of the substructure like cutting out damaged areas on steel girders with the aid of a plasma cutter and the new welding of carrier parts had become necessary. A maintenance team of five carried out all works successfully from October 22 – 28, 2020.
