This weekend, the 177-metre long railway bridge across Rozenburgsesluis was successfully installed on location. The bridge was correctly positioned by Saturday evening, 4 April, with work being rounded off just before 6 p.m. – earlier than planned. The railway bridge forms an important feature of the Theemswegtracé, a new part of the port railway line with a total length of over 4 kilometres. The second steel arch bridge will be installed next month. The first train is expected to drive along the Theemswegtracé by late 2021.


The bridge, which was manufactured by the Belgian firm Iemants, uses 4,500 tonnes of steel and has a span of 176.8 metres. With a height of 30 metres and a width of 20 metres, the structure offers enough room for a dual track railway.

Building consortium

The SaVe building consortium, formed by BESIX, Dura Vermeer, Mobilis, Hollandia and Iemants, was commissioned by the Port of Rotterdam Authority to build the substructure for the Theemswegtracé, a 4-km long railway route that incorporates a concrete overpass and two steel arch bridges.

Solving the bottleneck

Involving an investment of € 300 million, the Theemswegtracé presents a solution for potential issues with the Caland Bridge near Rozenburg. This steel vertical-lift bridge for railway and road traffic is part of the Betuwe Route and links Rotterdam’s port area with the European hinterland. For sea-going vessels, the vertical-lift bridge forms the gateway to Brittanniëhaven. “The Theemswegtracé is in line with the Port Authority’s policy to increase the sustainability of Rotterdam’s connections with the hinterland and raise efficiency in rail, road and shipping traffic. Considering the expected growth in rail freight transport and the increase in shipping movements from and to Brittanniëhaven, the Port Authority believes that in time, rail transport could run into a capacity bottleneck. The construction of the Theemswegtracé effectively resolves this bottleneck,” says Port Authority COO Ronald Paul.
