The particular challenge lay in the positioning of the supports on a narrow protrusion of land in the river Neckar. The steel superstructure, which weighed approximately 5,000 tonnes, was raised on to a steel trellis construction that was specially created for the project. The A6 motorway was completely closed at night to permit the trouble-free replacement of the bearings. Each of the pot bearings weighed approximately five tonnes.
Neckartal crossing
A number of pot bearings were replaced at the Neckartal crossing on the A6 motorway near Heilbronn at the request of the Stuttgart Regional Council.
