Ambitious infrastructures accommodating the growth of rail transport to the port of Rotterdam

Construction of a four-kilometre elevated railway viaduct, including two metal arch bridges. The Theemsweg rail link will considerably improve the accessibility and connection of the port of Rotterdam to the European hinterland.

New railway line

The new railway line will run for around 4 km along an elevated rail viaduct and over two arch bridges and connect back to the existing railway line at the A15.

The Port of Rotterdam Authority has awarded the building contract for the substructure to the SaVe consortium, consisting of BESIX, Mobilis, Dura Vermeer, Hollandia and Iemants. The project is financed by the European Union, the Port Authority and the Dutch Ministry of Infrastructure and Water Management.

Building work began in September 2018.

Our solution

The Theemsweg railway line is intended to solve the train traffic capacity bottleneck that is expected from the increasing rail and shipping traffic to and from the Brittanniëhaven in Rotterdam's Botlek port and industrial area.

The main problem is the Caland bridge at Rozenburg. This steel lift bridge for train, road and slow traffic in the Rotterdam port area also gives ships access to the Brittanniëhaven. By displacing the railway line, the growing train traffic will no longer be interrupted by shipping traffic, which will considerably improve the global traffic flow.

The environment will also experience less noise pollution from passing trains.
