The bridge is located to the north of Winsen (Luhe), Germany, and crosses the Laßrönner Weg over the Ilmenau river. It was built in the early 1980s as a prestressed concrete structure on a scaffolding and can be driven on in one lane. Two oncoming vehicles cannot pass each other on the superstructure due to the lane width of 3.50 m (11.5 ft).
The superstructure consists of a three-span girder with span lengths of 33.0 m (108.3 ft) – 47.0 m (154.2 m) – 33.0 m (108.3 ft). The cross-section is modelled as a T-shaped beam with a constant height. The flanges are tapered. The prestress is provided by garland-shaped tendons inserted in the girder web. In the plan view, the superstructure is straight and crosses the Ilmenau river perpendicularly. The central piers and abutments are deep-founded, and the access points to the structure are provided by embanked ramps.
The recalculation of the bridge was carried out in accordance with the recalculation guideline. For this purpose, RFEM and the Tendons add-on were used. An important aspect was the free geometric definition of the distribution of the tendons using NURBS lines in RFEM 6.
