In January 2016, through Eiffage Concessions, Eiffage won the 30-year public-private partnership contract for the A94 motorway between Forstinning and Marktl in Germany.
Isentalautobahn, the company created especially for this project, is owned in equal parts by Eiffage, Berger Bau GmbH, and Wayss & Freytag Ingenieurbau AG (a subsidiary of the Royal BAM group). The Southern Bavarian Autobahn Authority assigned it the design and construction of a new 33 km stretch of dual carriageways between Pastetten and Heldenstein, along with the maintenance and operation of the entire 77-kilometre section for the duration of the contract.
Isentalautobahn made the new motorway operational on Tuesday 1 October 2019, a month ahead of scheduled completion of the works.
These included the construction of:
- 22 km of noise reduction barriers;
- 66 km of protective fencing to safeguard wild animals;
- 57 artworks, including four more than 300 metres long;
- 640,000 m² of low-noise asphalt;
- 1 operations centre at Ampfing;
- 2 rest areas.
The operational phase also involves eco-balancing measures offsetting the project’s impact on biodiversity, perfectly complementing the Eiffage Group’s commitments in this area.
The project represents a total investment of €540 million.
