Extension of the A 94 Motorway: Lappach Viaduct
The A 94 federal motorway runs from Munich towards the north-east to the town of Pastetten, Germany. A section from Pastetten to Dorfen has been built as an extension of this motorway.
One of the parts of this 17.4 km long section is the Lappach Bridge that has been built using the cantilever construction method. The new bridge has two 85 m long main spans and two 58.5 m long side spans. The bridge passes over the Isen Valley at a height of up to 15 m and is supported by large-diameter bored piles. The width between the guard rails is 29.62 m.
For internal post-tensioning of the cantilever erection and the deck slab, DSI produced and supplied a total of 121.12 t of 19-0.62" and 22-0.62", St 1570/1770 Prefabricated Tendons. In addition, DSI produced and supplied 34.1 t of external Type SUSPA Systems Wire EX 66 Wire Tendons in individual lengths from 61 to 231 m.
DSI’s services also included the installation, stressing and grouting of the internal tendons in accordance with the approval Z-13.1-129 as well as the installation and tensioning of the external wire tendons.
