Description
PPP pilot project, Miltenberg bypass Relocation of the St 2309 near Miltenberg with a new Main bridge
Detailed planning by the PPP Miltenberg-Ingengieurbauwerke planning association (Büchting+Streit GmbH/Igl, Putz + Partner, Ingengieur- und Planungsgemeinschaft)
Share of Büchting+Streit: Mainbrücke Miltenberg BW 11 + 12
A special proposal from Büchting+Streit and the architect J. J. Zimmermann, Darmstadt, will be used for the cantilevered prestressed concrete box girder bridge.
Special features
Through close cooperation between engineer and architect, the supporting structures and a convincing and simultaneously subordinate design could be consistently worked out here.
Examples of this are the change in the span in the foreland – which statically improves the tension of the appearance in a favorable and logical way – and the design requirements from the construction through the crossing angle of the substructure to the superstructure of approx. 70 gon – which is excellently solved in terms of design through the formation of perpendicular webs and the clear separation of the orientation at the lower edge of the superstructure.
The sketches show the very fruitful cooperation between engineer and architect in the situation of the power opening when developing the logical and design-wise convincing solution.
