About Fehmarnbelt Tunnel

Welcome to the Fehmarnbelt Tunnel Blog! During the coming months I will describe our project and respond to any questions and comments that our design may trigger.

The Fehmarnbelt Tunnel project comprises a conceptual design of the 18km long immersed tunnel as well as a design for Plan Approval and subsequently a full tender design.

The Fehmarnbelt tunnel will be more than five times the length of the tunnel under Øresund linking Denmark and Sweden, and more than three times the length of the Trans-Bay Tube Bart Tunnel in San Francisco in California, the current world record holder.

The tunnel will cost around €5 bn to build. At the moment the travel time with the ferry is 45 minutes excl. waiting time – when the tunnel is ready to open in 2020 the travel time for car passengers will be shortened to 10 minutes and by train it will only take 7 minutes.

Ramboll, Arup and TEC have designed the immersed tunnel solution and the solution forms the basis for the Environmental Impact Assesment (EIA) report and the authority approval in Germany.

  1. Hi,

    I have graduated with an MSc Civil Engineering degree from University College London. I think this project is going to be a true engineering feat. I know that Ramboll has been widely involved in Geotechnical investigations and Arup has designed the Fire Safety & Ventilation Systems for this project but can you give me some more details regarding what part of this project each company is working on? Also, what kind of innovative solutions have you devised to overcome challenges in this particular project?

  2. Hello,

    I am a Greek Civil-Geotechnical Engineer and I am currently engaged as Chief of Geotechnics in Athens Metro System in Athens, Greece.
    I discovered quite recently this big Project. I started receiving news for this crossing mainly the Femern A/S webpage and consequenlty I realised the presence of Ramboll and Arup groups to be responsible for the design.
    It should be a real challegence for an engineer to be engaged with such a unique crossing. I am interested about a possible future involvement within this Project and threfore I downloaded relevant infos regarding the progress of the investigations, the relevant studies, etc. for to be more familiar with the published Crossing’s issues.
    I would appreciate any suggestions regarding the existing infos of the Project and its evolution.

    Best regards frm Athens
