The old Wolbecker Strasse bridge, located right next to the site of the new bridge, offered spectators a front row seat to this show. And what an extraordinary show it was! To start, the bridge itself is a far cry from the conventional sort – this elegant, slim, arched bridge appears to be symmetrical but in fact the two sides are not quite identical. A bridge with a twist. It truly is a work of art, not just in its design but also in the way it was produced. For the steel construction specialists who worked on it, overcoming the technical challenge of bending the two arches proved a bold feat indeed.
The project got off to a late start due to the complexity of the construction task and the time required to prepare for it, which was longer than expected.
At last, the time came to install this unique arched bridge, with a length of over 67 metres and weighing more than 550 tons. To achieve such a large-scale task, the Wagenborg Nedlift team brought a massive amount of equipment to the site, including a pontoon, the Modular Support System, support beams, mobile cranes, SPMTs, climbing jacks and a sliding system.
Now, a carefully orchestrated combination of horizontal and vertical conveyance techniques, conceived by the engineers at Wagenborg Engineering, could finally start.
Watch the WDR story on the bridge installation too.
Now that the new bridge has been installed, the access roads need to be finalised before the bridge can be used. And even then, the work still isn’t finished! The old bridge will be removed next summer. The old abutments will be completely rebuilt and in summer of 2022 the new bridge will be shifted sideways so that it takes the place of the old bridge.
So, it will take some time yet, but the patience of Münster’s residents will certainly pay off!
The Wollbecker Strasse bridge is not the first bridge that Wagenborg has installed. The bridge specialists were also responsible for the Schillerstrasse bridge. Wagenborg has plenty of experience working ‘on land’ as well: in November 2020 the company installed a 2000-ton rail viaduct in the B481.
The Dortmund–Ems Canal connects the eastern Ruhr region with the Emden seaport. It is an important transport route in western Germany. Currently, the canal is being widened and deepened to make inland shipping possible for larger vessels.
