A81 Autobahn Immensitz Bridge

• Due to damage it was necessary to dismantle and rebuild the Immensitz Bridge. Harrer Engineering were commissioned to redesign both superstructures and to recalculate both the existing substructures for the new loads and the existing superstructures for the period up until reconstruction for routing all traffic on the carriageway not being demolished/rebuilt. During this time, the demolition of the superstructure, the repair of the existing components and the new construction of the superstructures were put out to tender.

• Single-cell pre-stressed concrete box girder for each carriageway

• Prior damage
• Recalculation of the substructures
