The tight schedule meant that it was necessary to deliver the auxiliary bridge from Konz and to commence the scheduling of personnel and machinery as quickly as possible. Another factor that made the project even more difficult was that an additional mobile crane was needed to serve the new bridge to complement our railway slewing crane. The required logistics constituted a further challenge: the extension of the A 49 motorway is located on one side of the bridge. But we were able to cooperate with the German Federal Armed Forces to arrange the delivery of the shipments from the accessible side.
The work flow:
Being well prepared meant that it was possible to commence removing the damaged bridge as planned on 20 May. Our colleagues from the repair department started work on the abutment and the wing wall at around 4.30 a.m. and completed it by around 3.00 p.m. on 22 May. The auxiliary bridge was then put in place with the help of our railway slewing crane.
The completion of the work was announced at the specified time once the rails had been laid and the usual superstructure work, such as tamping and welding, had been carried out!
