Second construction phase successfully installed
With the lifting of the A46 Westring bridge, an eventful April came to an end for our bridge builders. In the night from April 25 to 26, the 2nd construction phase of the motorway bridge was successfully installed.
Two 300 t cranes at the abutments and a 750 t crane below the bridge ensured that the steel components could be lifted in. The parts were delivered over the bridge, which had already been built in the 1st construction phase, by means of heavy transporters, slewed by two cranes and set down on the new piers.
First, the two outer bays were lifted, each consisting of two hollow boxes with a length of approx. 37 m. Then followed the end cross beam and the cross beam on the pier. Thus the two hollow boxes were connected with each other.
Finally, the bridge was completed by the two 18 m long central components which were delivered underneath the bridge and lifted in place with the 750 t crane in a single lift.
The total length of the three-span composite steel bridge is 105 m with a total superstructure width of 36 m. 1000 t of steel were used for the entire steel construction of the structure.
