The“mono-arch” mostly takes into account to the oblique crossing situation. Thus,the arch structure crosses almost perpendicularly the motorway and diagonallythe superstructure and thus counteracts from a structural and visual point ofview the obliqueness of the bridge. The regularly arranged suspension cablesallow a very slenderly designed bridge deck which unfolds its appeal from everyviewing angle. The superstructure, designed as an oblique girder grid incomposite construction method, could be implemented with a slenderness of l/h =82.0 at a span width of 108.30 m.
