On 26 January, CER Consortium lifted a beam weighing around 414 tonnes over the railway and placed it on the corresponding support. The work was performed during the train-free period at viaduct Noord, near the APM Terminals at Maasvlakte II. This was not an easy job and required thorough preparation.
Viaduct Noord is approximately 600 metres long. The civil engineering structure crosses three railway tracks at the location of the support on which the beam was to be placed. This support consists of two pillars topped by a beam of about 22 metres long, 2 to 3 metres high and 2.8 metres wide.
