Buckinghamshire-based bridge specialist Knight Architects has won a competition to design four crossings over a rail line in Germany
Working with local firm Schüβler-Plan, the practice will design the road and pedestrian bridges in Darmstadt.
The structures will range from 25m to 53m and replace existing bridges that have reached the end of their natural lives.
Two of the bridges were developed in detail, while the others were sketched in outline.
Knight Architects said a common design language was found to link the bridges together.
It said the spans of each bridge were enlarged to allow minimal disruption to the green edges of the rail corridor, which links Frankfurt and Stuttgart.
A prefabricated steel composite cross-section will sit on in-situ concrete abutments allowing for rapid construction and minimum disruption.
Each bridge has a colour coded lighting scheme to allow users to orientate themselves when looking at and from the structures.
Knight is already working on bridges over rail lines in Ulm and Opladen.
Last summer AJ reported that the practice had won an open contest to design a 3km-long bridge in Helsinki
