The independent regulatory authority in Kiel is responsible for the consultation and is currently documenting all the responses before sending them on to the project teams.

The Fehmarnbelt fixed link's German section must be approved by the German authorities before construction can get underway. In Denmark, the Fehmarnbelt fixed link's Danish section was approved by the adoption of the 2015 Construction Act.

"We're looking forward to receiving all the responses from the regulatory authority in September," says Claus Dynesen, Femern A/S Project Director. "We will then begin the process of analysing them and, together with the authorities in Schleswig-Holstein, assess the next steps. We at Femern A/S and our co-applicants on the German side, LBV Lübeck, will respond to all questions. We're ready with our team of internal and external German experts to provide comprehensive answers to all the questions raised."

The Fehmarnbelt project aims to construct an 18km-long immersed tunnel between Denmark and Germany. Past estimates have put the project at USD 7.3bn.
