Another milestone successfully completed
The second shifting of the bridge north of Bamberg was successfully completed by our technicians on the weekend 17th/18th April 2020.
In the course of the replacement and reconstruction of the Bridge 93b of the BAB A73 Bamberg-Lichtenfels, the steel construction (approx. 1,400 tons) of the steel composite structure was shifted by 45 m over the B4 and the railway line to be crossed with the beginning of the closing break of the German Railway on Saturday and reached the auxiliary pier as planned.
On the following Sunday, the remaining shift took place with a total of 70 m to abutment 40. During the next weekend operation the bridge was then stacked by 1.30 m to its intended final position.
The composite steel bridge consists of two separate superstructures (section 1, Lichtenfels carriageway and section 2, Bamberg carriageway). The two separate superstructures are antimetrically designed, geometrically particularly challenging trough structures made of steel with a concrete roadway slab. The total length of the three-span bridge is 150 m with a total superstructure width of 37.20 m. For the entire steel construction of the structure 2800 tons of steel are required.
