The Theemswegtracé is a four-kilometre long elevated railway viaduct, including two metal arch bridges, that replaces the old railway line. That old railway line ran over the Caland Bridge, a vertical lift bridge that had to open multiple times a day for freight ships to sail through and thus interrupting train traffic. Thanks to the new line, trains are no longer hindered, which leads to a better accessibility of the port of Rotterdam to the European hinterland. On top of that, time is saved, CO2 emissions are reduced and capacity is increased.
The project was awarded by the Port of Rotterdam to the SaVe consortium, consisting of BESIX, Mobilis, Dura Vermeer, Hollandia and Iemants. Works began in 2018 and were finished in October 2021.
