A central
urban transport connection
On behalf of the city of Bochum, Wayss & Freytag is realising the replacement construction of the Lohring Bridge over nine Deutsche Bahn railway tracks.
The approximately 102 metre long structure is being built as a steel composite construction with a box girder cross-section and spray-galvanised corrosion protection system - a sustainable solution with a projected service life of up to 100 years.
The foundations were laid on 37 large bored piles with a diameter of 1.5 metres. V-shaped centre supports and integral abutments ensure a low-maintenance structure with maximum stability. A particular challenge was the realisation during ongoing rail traffic with precisely coordinated track possessions.
In addition to the bridge construction, the project also included the construction of new cycle paths and footpaths as well as the connection via a roundabout. The new Lohring Bridge fully restores a central urban transport link and thus makes a significant contribution to Bochum's infrastructure development.
