Project description

The high speed railway line from Schiphol Airport to Antwerp. For this railway line a number of large works have to be constructed. Two of them are the crossings of the river Oude Maas and the river Dordtsche Kil which are done by immersed tunnels. The enclosed parts of the tunnels are 1500 m. The sections below the rivers will be constructed with the immersed tunnel technique, with seven elements of 150 m each. The cross section comprises two tubes with one track each. The tunnel is suited for trains with a cruise speed of 300 km/h.
