Description of project

Extensive maintenance works of the road surface and bridges took place on the S06 Semmering dual carriageway in the district of Oberaich – Niklasdorf, km 83.824 – km 88.770, both lanes. Our order comprised the following points:

The bridges had a length between 5.90 m and 96.50 m and up to three fields with span widths between 5.60 m and 50 m. The overall area of the bridges was between 56.10 m2 and 1,045 m2. The bridges were built as loosely reinforced slabs, loosely reinforced or prestressed t-beams or as prestressed concrete box girders.
