In Rotterdam’s port complex, the port (or first) section of the Betuwe Route is to be redirected. The new route, the Theemswegtracé, will be completed in about 2021 and will provide a solution to the problems associated with the Calandbrug near Rozenburg.

The Theemswegtracé is approximately 4km long and will run from Merseyweg, over a raised railway viaduct along Theemsweg, all the way up to Moezelweg via Neckarweg. The railway line will pass 2 arched bridges (by the Thomassen Tunnel and the Rozenburgse Sluis) and link up again with the existing track where it meets the A15. Modifications will have to be made to roads, railway lines, cables and pipeline corridors in connection with the construction of the Theemswegtracé.

Problems with rail transport

The Theemswegtracé provides a solution to the problems associated with the Calandbrug near Rozenburg. This steel vertical lift bridge for rail, road and slow traffic in the Rotterdam port area is the connecting link in the Betuwe Route to the hinterland. For ocean shipping, the vertical lift bridge provides access to the Brittanniëhaven.
In 2020, the Calandbrug will reach the end of its technical lifespan. At the same time, a capacity bottleneck for rail traffic is anticipated, due to the expected growth in rail transport, as well as ocean shipping traffic to and from the Brittanniëhaven.

Importance of access to port of Rotterdam

Good accessibility and a good connection with the hinterland are very important for the port of Rotterdam. By road, by rail and by water. For this reason, the Port of Rotterdam Authority is investing in the Theemswegtracé, along with the Government and the European Union. The Port of Rotterdam Authority is coordinating and realising the project in conjunction with ProRail. The Ministry of Infrastructure and the Environment is preparing the decision process.


Following the exploratory phase, the project is now at the stage of detailing the plan. On the basis of an environmental impact assessment (project EIA), the Theemswegtracé will be worked out in the (Draft) Route Decision during this phase. When this has been adopted by the State Secretary for Infrastructure and the Environment, work on the Theemswegtracé will start in 2017.
The consultation exercise is being organised via Platform Participatie, under the auspices of the Ministry of Infrastructure and the Environment.
