Mammoet has concluded the second major bridge replacement at Amsterdam Centraal Station, following its successful completion of the first in 2025. Five bridges are being upgraded in total, with this work forming part of the High-Frequency Rail Transport programme led by ProRail, which covers track optimisations, infrastructure adjustments and civil work inside the station building, aimed at enabling more trains to run to and from the station in future.

Working alongside construction company Dura Vermeer, Mammoet managed the load-out, transportation and installation of three steel deck sections manufactured by Hollandia Infra that make up the second bridge, two components of 28,5 m and 275 t, and a middle section of 21 m and 175 t.

As the station is in a busy capital city, getting the new bridges to site was a complex engineering and logistical challenge. Mammoet’s solution was to transport the sections on water rather than roads, to minimise disruption and allow the station to remain open while the work was being carried out.

Each bridge section was delivered to the Oostertoegang side of the station on a flat-top barge. There, the barge was partially submerged so that it could pass underneath a low footbridge.

Once in position, the sections were rotated 90 degrees using Mammoet self-propelled modular transporters (SPMTs), before being jacked up using specialist lifting equipment. While the first bridge replacement used Mammoet’s Mega Jack 300 system for the final jacking operation on the centre section, a different method was used this time as there was less space for the bridge sections to manoeuvre.

“Previously, we used our Mega Jack 300 system and SPMTs to lift and rotate all deck sections on the deck of the barge and then drive them off and into position,” says Leo de Vette, project manager at Mammoet. “This time, however, we are working between two bridges, so we had to consider the decks and columns of the old bridges, as well as those of the new bridge we installed last year. For this reason, we had to first manoeuvre and rotate the new sections underneath these bridges, and then jack them up using a four-point lifting system which was assembled on the quayside.”

This four-point lifting system is essentially four large hydraulic cylinders that can all extend at the same speed. Sitting inside tracks, they can be moved into different positions for precise movement and lifting.

To allow the final central section to be installed, the pile on which it would rest was built after the span was roughly positioned. First, the final section was floated into position at the right angles to the installation direction. Next, it was rotated 90 degrees and lifted.

The centre section was then set down on consoles on the other two already-installed bridge sections, taking its weight. The central bridge column was then built, to which Mammoet returned to lower the centre section onto it.
