Two wildlife crossings on Fyn

As part of the widening of the Fynske Motorvej from four to six lanes between Odense Vest, Blommenslyst and westward to Ã…rup, we have tunnelled two wildlife crossings.

The first wildlife crossing was constructed at Gadsbøllevej and the second at Hønnerupvej. The hills in the landscape create a natural funnel here, and at the bottom of these, we tunnelled 60 m and 62 m long wildlife crossings under the motorway, without disrupting the flow of traffic.

60 and 62 m long tunnels

The tunnelling was carried out using our own MTS tunnelling machine equipped with a 1,600 mm diameter boring unit. As we drilled through, the tunnels were lined with IBF concrete pipes.

What made this project unique was that it was executed above ground level and in the elevated level of the motorway.
