Exemplary without example
The A3 motorway crosses Germany from the Dutch to the Austrian border. This European west–south connection has six traffic lanes. GRASSL designed the beginning of the new motorway section at the Fürth–Erlangen interchange – sustainably and innovatively.
paving the way
Traditionally delicate meets robust. The innovative union of arch and truss bridge allows the design of an extremely shallow span straddling the approximately 70 m wide motorway without any intermediate supports. The structure exudes elegance from all angles due to the acrylic glass panels in the railings, a soffit with an exceptional design and steel panels that refract the light. Discretion meets intelligence: linear drainage and a conscious decision to forego wear parts significantly improve the durability of this extraordinary structure.
creating construction culture
True creativity may start with the big picture, but the importance of details cannot be denied. By working together creatively, an engineering team can rapidly generate a visually pleasing solution in terms of landscape, traffic and the environment. Many cars cross arch bridges. And also truss bridges. The arch truss bridge – a unique structure: you’d better drive through. // don’t miss it.
