The road surface is being widened to 12.5 metres and fundamentally renovated on the A81 near Tauberbischofsheim. The Muckbach and Schüpfbachtal bridges are being replaced together because of their close proximity in order to make use of synergies. The planning includes the widening of the cross-section of the road surface, optimisation of the gradients and cross slopes and will be carried out using BIM technology.
