We verbeteren de bereikbaarheid van de haven

11 May 2021
How can we help you?

In the Rotterdam port area, we are relocating the Port Railway Line over a distance of about four kilometres: the so-called Theemswegtracé or Theemsweg Route. No one driving along Theemsweg can fail to see the 4-kilometre-long viaduct of the Theemswegtracé.

Festive open day at Theemswegtracé

The construction of the Theemswegtracé is almost complete. That is why we organised an open day on 9 October. During the day, project members and interested parties could take a look at the completed work of art. We would like to thank those involved in the project and people living in the vicinity of the Theemswegtracé for the good cooperation. We are proud to show what we have built: a new viaduct with over four kilometres of elevated track, two steel arched bridges and a trough bridge.

SaVe and VolkerRail

As from 2017, the SaVe construction team built two steel arched railway bridges. In January 2021, this construction work was transferred to VolkerRail to build the railway on it.


Since the start of the project, some impressive images have been shot of the activities on the Theemswegtracé. The film shows a summary from 2017 till today.

The Theemswegtracé runs from Merseyweg, on a railway viaduct alongside Theemsweg, all the way up to Moezelweg via Neckarweg. The railway line passes two arched bridges (near the Thomassen Tunnel and the Rozenburg Lock) and links up again with the existing track where it meets the A15 motorway. The first freight train is to drive on the new route in November 2021.

Merseyweg and N15Y to Maasvlakte closed

At the N15Y, all materials and work traffic will get onto the construction work via a temporary slip road and will leave via an exit at Merseyweg (south). This logistical solution is intended to relieve Theemsweg and Neckarweg as much as possible. As a result, the N15Y (through traffic crossing the Calandbrug in the Maasvlakte direction) and Merseyweg are already closed and will remain closed until the end of the project.

Diversion for through traffic Calandbrug in Maasvlakte direction

Traffic crossing the Calandbrug with destination Maasvlakte will be diverted until the end of 2021. Through traffic is diverted via the Saarweg roundabout to Moezelweg and can get back onto the A15 near Merwedeweg.

Closure Merseyweg prolonged until spring 2022

Merseyweg (south) will remain closed until the spring of 2022. Traffic is diverted via Botlekweg and Clydeweg. The bicycle path remains open.

Port Railway Line closed for six days

The Port Railway Line will be closed from 2 until 7 November 2021 (5:00 a.m.), from the Botlek yard to the Europoort yard, so that the Theemswegtracé can be connected to the existing Port Railway Line and test drives and system tests can be performed. Please contact the project team if this affects your freight transport or your need of freight transport via the Port Railway Line. Together with you, we will discuss what can be done.


The new route is part of the Betuwe Route, which connects the western port area with the hinterland. Once the track has been rerouted via Theemsweg, rail traffic will no longer cross the Calandbrug and will no longer be delayed when the bridge is raised for shipping.


It is very important to the port of Rotterdam that accessibility and connections with the hinterland by road, rail, or water leave nothing to be desired. For this reason, the Port of Rotterdam Authority is investing in the Theemswegtracé, along with the Dutch government and the European Union. 


The Port of Rotterdam Authority coordinates and realises the project in conjunction with ProRail and the Ministry of Infrastructure and Water Management.
