To develop and improve the Neckar Valley cycle path this bridge crosses the Neckar with an approximate length of 100m. With a width of 3.00m it provides enough space for pedestrians and cyclists. The S-shaped design is oriented to the connecting infrastructure. The considered load cases of 5,0kN / m² is in accordance with DIN 1991-2. The chosen design in form of a timber bridge with spans of 25,65m / 44,50m / 25,65 follows in ground plan an S-shape. The major span is straight at an angle of 85 gon above the Neckar. Both flood plain areas are curved in plan using a radius of 65,25m. On the Eastern side of the river the arc extends to the north, on the west to the south. For an efficient utilization of material the cross-section is graded according to the stress usage. The continuous beam creates moment diagram with zero crossings in the main span, which are designed as so-called Gerber hinge. In this way the design achieves sensible transport dimensions and a simplified assembly.
